ORDER AMENDING OPINION AND DENYING PETITION FOR REHEARING AND PETITION FOR REHEARING EN BANC AND AMENDED OPINION
ORDER
The majority opinion filed on August 18, 2004, is amended as follows:
At 379 F.3d at 1108, replace the first sentence of the paragraph which begins “Regarding the activity of learning ...,” with the following:
Regarding the activity of learning, Wong’s claim to be “disabled” was contradicted by his ability to achieve academic success, and to do so without special accommodations.
At 379 F.3d at 1108-09, replace the paragraph which begins on page 1108 and extends to the next page with the following:
The relevant question for determining whether Wong is “disabled” under the Acts was not whether he might be able to prove to a trier of fact that his learning impairment makes it impossible for him to keep up with a rigorous medical school curriculum. It was whether his impairment substantially limited his ability to learn as a whole, for purposes of daily living, as compared to most people. The level of academic success Wong achieved during the first two [1055]*1055years of medical school, without any special accommodation provided to him by the school, made that proposition implausible. His record was to the contrary. Because the factual context made implausible his contention that he was disabled in the activity of “learning” as compared to most people, he was required to “come forward with more persuasive evidence than otherwise would be necessary to show that there is a genuine issue for trial.” Blue Ridge Insurance Co. v. Stanewich, 142 F.3d 1145, 1149 (9th Cir.1998) (citing Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 587, 106 S.Ct. 1348, 89 L.Ed.2d 538 (1986)). He did not present sufficient evidence in support of his contention to establish a triable issue of fact.6
The next sentence, beginning “As for the activity of reading ...,” starts a new paragraph (correctly shown at Slip op. at 11562, but incorrect at 379 F.3d at 1109). That paragraph is otherwise unchanged.
At 379 F.3d at 1109, delete the first paragraph of footnote 6 such that the footnote consists only of the remaining paragraph.
The dissenting opinion of Judge Thomas is amended, on 379 F.3d at 1110, by deleting the sixth sentence of the first paragraph, which is the sentence beginning with the words “At a minimum,.... ”
With the opinions as amended, Judges Beezer and Clifton have voted to deny the petition for rehearing. Judge Thomas has voted to grant the petition for rehearing.
Judge Clifton has voted to deny the petition for rehearing en banc, and Judge Beezer so recommends. Judge Thomas has voted to grant the petition for rehearing en banc.
A judge of the court called for a vote on the petition for rehearing en banc. A voté was taken, and a majority of the active judges of the court failed to vote for en banc rehearing. Fed. RApp. P. 35(f).
The petition for rehearing and petition for rehearing en banc, filed on September 8, 2004, are DENIED.
No further petitions for rehearing will be entertained.
OPINION
CLIFTON, Circuit Judge:
Andrew H.K. Wong alleges that the University of California discriminated against him in violation of the Americans with Disabilities Act (“ADA”) and the Rehabilitation Act1 when it denied his request for learning disability accommodations and subsequently dismissed him for failure to meet the academic requirements of the medical school at the University’s Davis campus. The district court granted the University’s motion'for summary judgment, concluding that Wong failed to present a triable issue of material fact as to whether he was “disabled” and thus legally entitled to special accommodations under those Acts.
Wong’s appeal thus requires us to consider the meaning of “disabled” under the Acts. More, specifically, it presents a question of whether a person who has achieved considerable academic success, beyond the attainment of most people or of the average person, can nonetheless be found to be “substantially limited” in reading and learning, and thus be entitled to claim the protections afforded under the Acts to a “disabled” person.
[1056]*1056This appeal also raises an issue regarding the exclusion of testimony by the district court on the ground that the expert witnesses in question were not timely identified. The district court excluded certain experts retained by Wong to respond to the University’s motion for summary judgment. Those witnesses were identified by Wong after a deadline set by the district court for identifying expert witnesses. Wong contends that the tardy identification was justified because he could not reasonably have anticipated the need for those witnesses, since he did not know that the University disputed his claim to be disabled under the Acts. He further contends that the late identification was harmless, given that the case had a scheduled trial date several months after the supplemental, though tardy, identification.
We affirm. We conclude that the district court did not abuse its discretion in declining to permit Wong to add the additional witnesses. The need for those witnesses could reasonably have been anticipated prior to the supplemental identification of witnesses. We also conclude that the evidence before the district court did not establish a genuine issue of material fact as to whether Wong qualified under the Acts as disabled. Wong contends that he has an impairment which “substantially limits [him in] one or more of the major life activities” and thus fits within the definition of “disabled.” See 42 U.S.C. § 12102(2)(A). The Supreme Court has concluded, however, that “these terms need to be interpreted strictly to create a demanding standard for qualifying as disabled.” Toyota Motor Mfg. Kentucky, Inc. v. Williams, 534 U.S. 184, 197, 122 S.Ct. 681, 151 L.Ed.2d 615 (2002). Interpreting those terms strictly and applying that demanding standard, Wong has not demonstrated that he is substantially limited in major life activities. We therefore affirm the district court’s judgment in favor of the University-
I. BACKGROUND
This court previously considered Wong’s disability discrimination claim in 1999, after the district court entered summary judgment in favor of the University on different grounds. We reversed the district court’s order and remanded for further proceedings, concluding that genuine issues of material fact remained as to the reasonableness of the accommodation in question and as to whether Wong was otherwise qualified to meet the medical school’s academic standards. Wong v. Regents of the Univ. of California, 192 F.3d 807, 826 (9th Cir.1999) (“Wong I”). Subsequently, the district court entered summary judgment again, on a different ground, concluding that Wong had not shown that he qualified as disabled under the Acts. The current appeal presents the question of whether the district court’s second entry of summary judgment was proper.
The facts of this case are outlined in detail in Wong I, 192 F.3d at 811-16. We briefly recount pertinent elements here, along with the history of the case subsequent to our previous decision.
As the district court observed, Wong’s academic history has been filled with contradictions. In kindergarten he was identified as suffering from a learning impairment, but in grammar school he was certified as a gifted student. In middle school he was assigned to a special class for assisted learning. While attending high school and college, he regularly requested extra time on assignments and essay examinations. To keep up with his college classes, he said that he spent all of his extra time outside of school reading for his classes. The effort paid off, however, for he graduated [1057]*1057from San Francisco State University, magna cum laudé, earning a B.S. in biochemistry with a cumulative grade point average of 3.54 out of 4.0. Wong went on to earn a master’s degree in cellular/ molecular biology from San Francisco State in 1984.
After taking the Medical College Admission Test four times, without special accommodations, he was able to obtain admission to the medical school at Davis. His admission was not based upon any special allowance for a disabled condition.
Wong started at the medical school in the fall of 1989. The medical school’s program consists of a four-year curriculum. Typically, in the'first two years, students take academic courses in basic sciences. In the third year, they complete six consecutive clinical “clerkships” in core areas of medical practice, and in the fourth year; they take a series of more specialized clerkships. Wong completed the first two years of the medical school program, the academic courses, on a normal schedule, with a grade average slightly above a “B.” He had also, passed the required national board examination immediately following the second year of school. Wong did not request or receive the benefit of any special accommodations during the first two years of medical school or in taking the national board exam. Through this point, he had not identified himself to the medical school as being “learning disabled” or in need of accommodations.
When the program moved to the clinical clerkships in the third year, however; Wong’s performance deteriorated substantially. He received a failing grade in his first clerkship and withdrew from his second after his midterm evaluation showed significant problems.2
Soon thereafter, his academic difficulties were compounded by a serious family problem: Wong’s father was diagnosed with lung cancer. The school granted Wong’s request to take time off to be with his father.' Wong used part of that time to do reading in preparation for upcoming clerkships, and after he returned to school, he passed three clerkships. Unfortunately, his problems did not end at that point. Ultimately Wong was diagnosed by the University’s Disability Resource Center (“DRC”) as having a learning impairment that limited his ability to process and communicate information.3 Based on the recommendation of the DRC, Wong requested extra time to read and prepare for his clerkships. When able to take several weeks off before a rotation in order to read in advance and prepare for it, Wong completed clerkships with passing grades and generally positive evaluations. There came a point, however, when Wong’s request for another eight-week reading period before his next clerkship, in Pediatrics, was denied. A school official later gave a number of reasons for denying Wong’s request, including that it was “unreasonable, unfair, and contrary to the purposes of the curriculum.”' Although Wong passed the written and oral exams for his Pediatric rotation, his ward performance was deemed unsatisfactory and he received a failing grade. After the relevant school committees concluded that Wong was not [1058]*1058qualified to meet the school’s academic standards, he was dismissed from the medical school in May 1995.
Wong filed a complaint in district court, alleging that the University violated his rights under the ADA by failing to accommodate his learning disability. The district court subsequently granted summary judgment for the University on two grounds: (1) that the accommodation sought by Wong was unreasonable, and (2) that the appellant was not “otherwise qualified” to continue his medical studies because he could not perform the tasks required by a doctor. Wong appealed. Our court reversed the district court’s judgment and remanded for further proceedings on the ground that Wong had raised triable issues of fact. Wong I, 192 F.3d at 826.
In Wong I we held that in order to establish a prima facie case of disability discrimination, Wong was required to produce evidence that:
(1) he is “disabled” as the Acts define that term; (2) he is qualified to remain a student at the School of Medicine, meaning that he can meet the essential eligibility requirements of the school with or without reasonable accommodation; (3) he “was dismissed solely because of [his] disability;” and (4) the school “receives federal financial assistance (for the Rehabilitation Act claim) or is a public entity (for the ADA claim).”
Id. at 816 (internal footnote omitted) (applying the factors set out in Zukle v. Regents of the Univ. of California, 166 F.3d 1041, 1045 (9th Cir.1999)). We noted that “[f]or summary judgment purposes, the University concedes that Wong has met the first and last elements of this test.” Id. The dispute then focused on the second element: whether Wong was “otherwise qualified” to satisfy the academic standards of the Medical School, with or without reasonable accommodation.
In this appeal, however, the University no longer concedes the first element, that Wong was disabled under the Acts. That is, instead, the primary focus of this appeal. On remand, the district court granted another motion for summary judgment brought by the University, this time based on Wong’s inability to establish a disability.
That motion for summary judgment was filed by the University after cut-off dates established by the district court for identification of expert witnesses and for discovery. After, a.status conference held on March 13, 2000, the court issued an order which set the close of discovery on August 13, 2000. The order stated that counsel was required to disclose, the names of any experts they proposed to offer at trial “not later than forty-five (45) days before the close of discovery,” which was June 29, 2000. The order also set the final pretrial conference for February 12, 2001, and scheduled trial to start on May 15, 2001.
The University’s motion for summary judgment was filed on September 1, 2000, about three weeks after the discovery cutoff date, about two months after the deadline for identifying expert witnesses, and about eight and one-half months before the scheduled trial date. It argued that Wong was not disabled within the meaning of the ADA. To support this contention, the University relied on its identified expert, Dr. Mark Lipian, who opined, among other things, that Wong was able to learn and work with greater facility than the average person.
Wong’s attorneys concluded that they would need additional expert testimony to rebut Dr. Lipian’s opinion. One of Wong’s previously identified experts, Dr. Kay Runyan, gave Wong a number of additional tests to support an opinion which was subsequently expressed in her declaration in opposition to the University’s motion for [1059]*1059summary judgment. She administered those tests with the help of an expert Wong had not previously retained or identified, Dr. Bianca Hirsch. Wong also retained Thomas Yankowski, a vocational counselor, to rebut Dr. Lipian’s contention that Wong was not substantially limited insofar as his ability to work.
Wong filed his opposition to the University’s motion for summary judgment on September 18, 2000, relying in large part on the work of these previously undisclosed experts. Two days later, Wong submitted a Supplemental Disclosure of Expert Witnesses, stating that he did not disclose these experts prior to his response to the University’s summary judgment motion because he had not anticipated the University’s challenge to his disabled status.
The University challenged Wong’s identification of additional expert witnesses after the expert identification deadline and the discovery cut-off date. That challenge was presented to the district court in the context of the University’s motion for summary judgment, with the University arguing that the court should not consider testimony by witnesses who had not been timely identified.
The district court agreed with the University on both subjects. On the challenge to Wong’s additional expert witnesses, the court excluded expert opinions and other evidence from Dr. Hirsch and Mr. Yankowski. The court also limited Dr. Runyan’s expert testimony to those opinions which were not based upon the testing conducted by Dr. Hirsch.
In the same order, filed January 11, 2001, the district court granted the University’s motion for summary judgment. The court concluded that there was not a genuine issue of material fact as to whether Wong was “substantially limited [in] the major life activities of learning, reading and working under 42 U.S.C. § 12102(A).”
As to the first two activities, the court concluded “that the record, taken as a whole, could not lead a rational trier of fact to find that plaintiff is substantially limited in the major life activities of learning and reading. See Price v. National Bd. of Medical Examiners, 966 F.Supp. 419 (S.D.W.Va.1997) (finding that plaintiffs were not disabled under the ADA because they were able to learn as well or better than the average person in the general population).” Wong’s prior academic success, which won him admission to medical school and which continued through the first two years of medical school, was viewed as fatally inconsistent with his claim to be disabled: “Given his previous academic success the issue translates to whether he can demonstrate that most people, or the average person, would not have difficulty with the third and fourth years of medical school.” Having so defined the question, the district court concluded that Wong did not make a sufficient showing that he was “disabled” as to learning and reading.
Regarding the major life activity of working, the district court concluded that Wong “will only be precluded from jobs that require very specific and detailed deductive reasoning in an information-intense, rapid-flux, time-pressured or stressful environment.” That assessment, the district court concluded, did not establish that he would be foreclosed from a broad range of jobs. “Given his academic achievements, however, and his intellectual skills, Mr. Wong has an enormous range of professional positions and occupations in which it is apparent that he could engage in successfully.” Thus, the court held that Wong had failed to demonstrate that he was substantially limited as to working.
Wong contends that the district court erred in (1) excluding the key expert witnesses that he argues could have estab[1060]*1060lished his disabled status, and (2) holding that he did not raise a genuine issue of material fact as to his disabled status under the Acts. We examine each contention in turn.
II. DISCUSSION
A. Exclusion of Supplemental Expert Testimony
Rulings regarding evidence made in the context of summary judgment are reviewed for an abuse of discretion. Domingo v. T.K., 289 F.3d 600, 605 (9th Cir.2002) (noting limited appellate review “even when the rulings determine the outcome of a motion for summary judgment”). The imposition of discovery sanctions are reviewed for an abuse of discretion. Yeti by Molly, Ltd. v. Deckers Outdoor Corp., 259 F.3d 1101, 1105 (9th Cir.2001).
The abuse of discretion standard is deferential, and properly so, since the district court needs the authority to manage the cases before it efficiently and effectively. In these days of heavy caseloads, trial courts in both the federal and state systems routinely set schedules and establish deadlines to foster the efficient treatment and resolution of cases. Those efforts will be successful only if the deadlines are taken seriously by the parties, and the best way to encourage that is to enforce the deadlines. Parties must understand that they will pay a price for failure to comply strictly with scheduling and other orders, and that failure to do so may properly support severe sanctions and exclusions of evidence. The Federal Rules of Civil Procedure explicitly authorize the establishment of schedules and deadlines, in Rule 16(b), and the enforcement of those schedules by the imposition of sanctions, in Rule 16(f). As we observed in Johnson v. Mammoth Recreations, Inc., 975 F.2d 604, 611 (9th Cir.1992):
As the torrent of civil and criminal cases unleashed in recent years has threatened to inundate the federal courts, deliverance has been sought in the use of calendar management techniques. Rule 16 is an important component of those techniques.
The March 15, 2000 pretrial order at issue here was clear in advising the parties, among other things, that an expert witness not identified by the deadline would not be permitted to testify, and that an expert would not be permitted to testify as to “any information gathered or evaluated, or opinion formed, after deposition taken subsequent to designation.”
Deadlines must not be enforced mindlessly, of course. Sometimes there may be good reason to permit an identification of additional witnesses after the established deadline. The pretrial order at issue here took that into account and itself established the standard for seeking relief from the order. It stated that no expert witness not timely disclosed would be permitted to testify “unless the party offering the witness demonstrates: (a) that the necessity of the witness could not have been reasonably anticipated at the time the lists were exchanged; (b) the court and opposing counsel were promptly notified upon discovery of the witness; and (c) that the witness was promptly proffered for deposition.”
Wong’s additional expert witnesses were promptly identified and offered to the University not long after the filing of the University’s motion for summary judgment, so factors (b) and (c) were likely satisfied. The district court concluded, however, that Wong failed to satisfy factor (a). That conclusion does not represent an abuse of discretion.
Wong argues that he could not reasonably have anticipated the need for the additional witnesses as of the date set by the pretrial order as the deadline for both parties to identify expert witnesses, because he did not know that the University [1061]*1061was disputing that he was “disabled”' under the Acts. He notes that it was the University itself which diagnosed his learning disability in the first place, and, further, that the University did not dispute that element of his case at the time of its first motion for summary judgment.
The diagnosis that Wong had a learning disability did not constitute a legal opinion or a concession that Wong was “disabled” under the meaning of the Acts, however. It is plain that having an impairment does not necessarily mean that a person is “disabled” for purposes of the Acts. Toyota, 534 U.S. at 195, 122 S.Ct. 681.
Nor does a decision by a defendant not to contest one element of a plaintiffs claim when bringing a motion for summary judgment mean or even imply that the given element will be conceded at the time of trial. There is nothing unusual about a defendant concentrating on limited aspects of a case in a motion for summary judgment, without waiving its right to contest other elements later, if the motion. does not end the case. As we explicitly noted in Wong I, one of the elements Wong had to prove was that he was “ ‘disabled’ as the Acts define that term.” 192 F.3d at 816. At that time, the issue of whether Wong was disabled under the Acts was not in dispute, because the University had conceded that element “for summary judgment purposes.” Id. But nothing required the University to concede that element for trial. A decision not to contest one essential element when moving for summary judgment based on a different essential element does not constitute a permanent waiver by the movant on the issue in question.
After Wong I, the University put Wong on some measure of notice that his disabled status would be challenged. In its status conference statement, filed with the district court on March 6, 2000, the University stated that “[rjecent United States Supreme Court cases have more clearly defined what constitutes a disability .:. such that defendant now believes that- an examination of the plaintiff is necessary and appropriate in order to address the issue of whether plaintiffs condition can be held to be a disability under the relevant statutes.”
The same filing announced that the University anticipated bringing a further motion for summary judgment. It does not appear that the University subsequently followed up with a specific request for an examination of plaintiff, but Wong points to no other statement or action by the University subsequent to that time which justified his professed belief that the University would not contest his condition as “disabled” under the Acts. Wong may have hoped that he would not be challenged on that element, but that is not nearly enough to support the proposition that he could not have reasonably anticipated the need to prove that element at trial. Wong I clearly set out four elements Wong would have to prove; and this was one of them. It was not unfair for the district court to expect him to prepare to do so, and to identify the witnesses he needed for that purpose, on a timely basis.
Moreover, as the district court observed in its order excluding Wong’s late-identified witnesses, “if plaintiff was in doubt he could have resolved the issue with contention interrogatories; he did not' do so.” Wong has not offered a response on appeal, let alone provided an explanation for that failure. Similarly, the subject could have been covered by discovery into the opinions held by Dr. Lipian, the expert witness relied upon by the University in its motion for summary judgment. The Defendant’s Disclosure of Expert Witnesses timely identified Dr. Lipian and described his anticipated testimony as including “the nature and extent of any learning disabili[1062]*1062ties the plaintiff had or has.” Wong could have taken his deposition or propounded interrogatories to ascertain his opinions, including the opinions subsequently .relied upon by the University in its summary judgment motion. Wong has not contended that Dr. Lipian did not properly respond to any such inquiries. If Wong was caught by surprise, it was not the University’s fault. Under those circumstances, we cannot say that the district court abused its discretion in concluding that Wong did not satisfy the requirement for adding expert witnesses after the disclosure deadline: that it was not the case that “the necessity, of the witness could not have been reasonably anticipated at the time the lists were exchanged.”
Wong also argues that the district court’s denial of his request to supplement his list of expert witnesses violated Fed. R.Civ.P. 37(c)(1). That rule states in relevant part:
A party that without substantial justification fails to disclose information required by Rule 26(a) or 26(e)(1), or to amend a prior response to discovery as required by Rule 26(e)(2), is not, unless such failure is harmless, permitted to use as evidence at a trial, at a hearing, or on a motion any witness or information not so disclosed.
The rule excludes evidence from an untimely disclosed witness unless “the parties’ failure to disclose the required information is substantially justified or harmless.” Yeti by Molly, 259 F.3d at 1106.
Wong argues, in effect, that he satisfied this test under Rule 37 for permitting testimony from a late-disclosed witness, because the late disclosure was either substantially justified, harmless, or both. We disagree.
Wong’s failure to identify necessary witnesses on a more timely basis was, in the eyes of the district court, and in the words of Rule 37, “without substantial justification,” for the reasons discussed above. Nor, it may be inferred, did the district court believe that the tardy identification was harmless, even though the ultimate trial date was still some months away. The same status conference order which set the deadline for expert identification and the completion of discovery also set a deadline for resolving pretrial motions, such as the University’s motion for summary judgment. In this instance, it appears that the University filed its motion about as late as it could while still complying with the schedule set by the court. If Wong had been permitted to disregard the deadline for identifying expert witnesses, the rest of the schedule laid out by the court months in advance, and understood by the parties, would have to have been altered as well. Disruption to the schedule of the court and other parties in that manner is not harmless. Courts set such schedules to permit the court and the parties to deal with cases in a thorough and orderly manner, and they must be allowed to enforce them, unless there are good reasons not to. The district court did not abuse its discretion here in refusing to permit Wong to supplement his disclosure with the additional expert witnesses and in barring testimony by and relying upon those witnesses.
B. “Disability” under the Acts
The ADA prohibits discrimination by public entities against qualified individuals with a disability. '42 U.S.C. §§ 12131-12132. The Rehabilitation Act similarly provides that “no otherwise qualified individual with a disability ... shall, solely by reason of her or his disability, be excluded from the participation in, be denied the benefits of, or be subjected to discrimination under any program or activity receiving federal financial assistance.” 29 U.S.C. § 794(a). The University is a public entity subject to these provisions.
[1063]*1063The key substantive issue in this case— the issue on which the district court granted summary judgment to the University— is whether Wong fell within the definition of “disabled” under the Acts. If the district court was correct in concluding that Wong was not “disabled,” then he did not qualify for the protections provided by the Acts, and summary judgment was properly granted against his legal claim. Wong’s argument on appeal is that he demonstrated a genuine issue of material fact as to whether he was disabled under the Acts, even with his evidence limited by the district court’s exclusion of untimely experts and opinions, discussed above. We review the district court’s summary judgment de novo, and we view the facts in a light most favorable to Wong. Fraser v. Goodale, 342 F.3d 1032, 1037 (9th Cir.2003), cert. denied, 541 U.S. 937, 124 S.Ct. 1663, 158 L.Ed.2d 358 (2004).
The plaintiff bears the burden of proving that he or she is disabled within the meaning of the Acts. Thornton v. McClatchy Newspapers, Inc., 261 F.3d 789, 794 (9th Cir.2001), later supplemented at 292 F.3d 1045 (9th Cir.2002); Wong I, 192 F.3d at 816. The ADA defines a disability as:
(A) a physical or mental impairment that substantially limits one or more of the major life activities of such individual;
(B) a record of such an impairment; or
(C) being regarded as having such an impairment.
42 U.S.C. § 12102(2).
The focus of our attention here is on subsection (A), which was the basis for the summary judgment entered by the district court and the subject of Wong’s argument on appeal.4 The consideration of whether a given condition constitutes a disability under subsection (A) involves three inquiries: (1) whether Wong’s condition is a physical or mental impairment; (2) whether the life activity as to which Wong alleges he is limited is a major life activity, and (3) whether the impairment substantially limits the identified major life activity. See Bragdon v. Abbott, 524 U.S. 624, 631, 118 S.Ct. 2196, 141 L.Ed.2d 540 (1998); Fraser, 342 F.3d at 1038.
For current purposes, there is no dispute as to the first question, whether Wong suffers from an impairment. The University’s Disability Resource Center diagnosed Wong to' have a learning disability or impairment that limited his ability to process and communicate information. At a minimum that is sufficient to create a genuine issue of material fact as to whether he suffers from an impairment. The district court did not base its summary judgment on a conclusion to the contrary, and the University does not argue that point on appeal.
Nor is there a serious controversy as to whether the limitations alleged by Wong involved major life activities. Wong contends that he was substantially limited in learning, reading, and working. Under the circumstances, we may assume that each of those activities qualifies as a “major life activity” for determining whether a person is disabled under the Acts.5
[1064]*1064The real dispute here is over the third inquiry: whether Wong offered sufficient evidence that his impairment substantially limited him in a major life activity. The district court concluded that he had not. We agree.
As noted at the outset of this opinion, we are pointed to that conclusion by the Supreme Court’s unanimous decision in Toyota Motor Manufacturing Kentucky, Inc. v. Williams, 534 U.S. 184, 122 S.Ct. 681, 151 L.Ed.2d 615 (2002). The Court stated that to “qualify as disabled, a claimant must ... show that the limitation on the major life activity is ‘substantial.’ ” Id. at 195, 122 S.Ct. 681 (brackets omitted). It observed that the word “ ‘[substantially’ in the phrase ‘substantially limits’ suggests ‘considerable’ or ‘to a large degree.’ ... The word ‘substantial’ thus clearly precludes impairments that interfere in only a minor way ... from qualifying as disabilities.” Id. at 197, 122 S.Ct. 681. Similarly, it held that the word “ ‘[mjajor’ in the phrase ‘major life' activities’ means important.... ‘Major life activities’ thus refers to those activities that are of central importance to daily life.” Id. And, it emphasized that “these terms need to be interpreted strictly to create a demanding standard for qualifying as disabled.” Id. (Emphasis added.)
The facts of the Toyota case illustrate the Court’s interpretation of the Acts. The plaintiff in that case suffered from carpal tunnel syndrome and tendinitis, which limited her ability to lift weight and to. engage in repetitive arm movements. She sued her former employer for violation of the ADA, alleging that it failed to reasonably accommodate her disability. The district court granted summary judgment to the employer, finding that plaintiff was not disabled. The Sixth Circuit reversed and reinstated her claim, holding that she was disabled in the ability to perform manual tasks, because her ailments prevented her from doing tasks associated with certain types of jobs, including her previous position on an automobile manufacturing assembly line.
The Supreme Court overturned the decision of the Sixth Circuit, however, holding that the court of appeals had erred by focusing on the manual tasks associated with plaintiffs job. Id. at 200, 122 S.Ct. 681. The Court elaborated: ‘When addressing the major life activity of performing manual tasks, the central inquiry must be whether the claimant is unable to perform the variety of tasks central to most people’s daily lives, not' whether the claimant is unable to perform the tasks associated with her specific job.” Id. at 200-01, 122 S.Ct. 681. It went on to note that “the manual tasks unique to any particular job are not necessarily important parts of most people’s lives.” Id. at 201, 122 S.Ct. 681. The manual tasks of central impor[1065]*1065tance to most people’s daily lives were described as things like doing household chores, bathing, and brushing teeth, and those activities, according to the Court, should have been considered in determining whether the claimant was “disabled” under the Acts, by reason of being- substantially limited in her ability to perform manual tasks. Id. at 201-02, 122 S.Ct. 681.
Our court interpreted and applied Toyota in the context of a different major life activity in EEOC v. United Parcel Service, Inc., 306 F.3d 794 (9th Cir.2002). In that case, employees of UPS with monocular vision who wanted to drive package vans but were not permitted to do so under the company’s vision protocols brought a discrimination action under the ADA. At issue was the major life activity of “seeing,” and specifically the question of whether the plaintiffs’ impairment constituted a substantial limitation on seeing such that they were “disabled” under the ADA. We concluded that:
[F]or a monocular individual to show that his impairment is a disability, the impairment must prevent or severely restrict use of his eyesight compared with how unimpaired individuals normally use their eyesight in daily life .... [S]ome visual impairment does not necessarily mean that the individual is substantially limited in seeing overall; put differently, it does not follow that seeing as a whole is substantially limited just because the individual has a deficiency in some aspect of vision. The critical inquiry is whether seeing as a whole is substantially limited for purposes of daily living.
Id. at 802-03. (Emphasis added).
The question for us, therefore, is whether Wong presented sufficient evidence to demonstrate that he was substantially limited in the specified major life activities for purposes of daily living, or as compared to what is important in the daily life of most people. He did not carry that burden.
Regarding’ the activity of learning, Wong’s claim to be “disabled” was contradicted by his ability to achieve academic success, and to do so without special accommodations. Most notably, Wong completed the first two years of the medical school program, the academic courses, on a normal schedule, with a grade point average slightly above a “B,” and he passed the required national board examination at that point, both without the benefit of any special accommodations. That is not to say that a successful student by definition cannot qualify as “disabled” under the Acts. A blind student is properly considered to be disabled, because of the limitation on the major life activity of seeing, even if she graduates at the top of her class. Nor do we say that a successful student cannot prove “disability” based on a learning impairment. A learning-impaired student may properly be considered to be disabled if he could not have achieved success without special accommodations. But a student cannot successfully claim to be disabled based on being substantially limited in his ability to “learn” if he has not, in fact, been substantially limited, as that term is used in the Acts.
The relevant question for determining whether Wong is “disabled” under the Acts was not whether he might be able to prove to a trier of fact that his learning impairment makes it impossible for him to keep up -with a -rigorous medical school curriculum. It was whether his impairment substantially limited his ability to learn as a whole, for purposes of daily living, as compared to most people. The level ’of academic success Wong achieved during the first two years of medical school, without any special accommodation provided to him by the school, made that proposition implausible. His record was to [1066]*1066the contrary. Because the factual context made implausible his contention that he was disabled in the activity of “learning” as compared to most people, he was required to “come forward with more persuasive evidence than otherwise would be necessary to show that there is a genuine issue for trial.” Blue Ridge Insurance Co. v. Stanewich, 142 F.3d 1145, 1149 (9th Cir.1998) (citing Matsushita Elec. Indus. Co. v. Zenith Radio Corp., 475 U.S. 574, 587, 106 S.Ct. 1348, 89 L.Ed.2d 538 (1986)). He did not present sufficient evidence in support of his contention to establish a triable issue of fact.6
As for the activity of reading, Wong’s contention was not that he could not read, but that, as a result of his learning disability, he read very slowly and often had to re-read material several times. He cited evidence, for instance, that his reading comprehension scores, when allowed to read without time limits, were at the 99.5 percentile, but under time constraints he read at the eighth grade level.7 In essence, it was argued that Wong read slowly, especially when compared to his own reading comprehension ability without time limits, or to others in his academic peer group. He did not, however, present evidence to the district court or argue to us that he was substantially limited in his ability to read for purposes of daily living, or as compared to what is important in the daily life of most people. That is the appropriate standard. In Toyota, the Court said that the ability to perform manual tasks should be evaluated not by what claimant’s job might require, but by claimant’s ability to perform household chores, bathe, and brush teeth. 534 U.S. at 201-02, 122 S.Ct. 681. In EEOC v. United Parcel Service, we referred to the ability to use eyesight in such daily life activities as driving, reading, using tools, and playing sports. 306 F.3d at 803. In this case, Wong has not established that he was unable to read newspapers, government [1067]*1067forms, street signs, or the like. Although his academic achievement is. not directly inconsistent with the contention that he is substantially limited in reading, as it was with the claim based on “learning,” the relationship between reading and academic success is sufficiently close to make that argument a difficult one to maintain. We agree with the district court that he did not present sufficient evidence to establish a triable issue of fact on that issue.
Wong’s argument that he was substantially limited in the major life activity of working depended upon the testimony of Mr. Yankowski, one of the experts excluded by the district court due to untimely identification. Because we have concluded that the exclusion was not an abuse of discretion, this argument necessarily fails, as well.
III. CONCLUSION
We therefore affirm the judgment of the district court. We admire Wong’s determination and his efforts to overcome his impairment, and we cán understand his disappointment at not being able to achieve this ambition. As the Supreme Court held in Toyota, however, “[mjerely having an impairment does not make one disabled for purposes of the ADA.” 534 U.S. at 195, 122 S.Ct. 681. By the demanding standards of the Acts, Wong is not substantially limited in a major life activity, so he does not qualify for the special protections the Acts provide for someone who is “disabled.”
AFFIRMED.
