UNITED STATES DISTRICT COURT FOR THE DISTRICT OF COLUMBIA
OKIA FERGUSON,
Plaintiff,
v. No. 21-cv-1201 (DLF)
KILOLO KIJAKAZI,
Defendant. 1
MEMORANDUM OPINION
Plaintiff Okia Ferguson, on behalf of her minor son K.J., challenges the Social Security
Administration’s (SSA’s) denial of K.J.’s claims for Supplemental Security Income benefits.
Before the Court are Ferguson’s Motion for Judgment of Reversal, Dkt. 13, and the Social Security
Commissioner’s Motion for Judgment of Affirmance, Dkt. 16. For the reasons that follow, the
Court will grant the Motion for Judgment of Reversal and deny the Motion for Judgment of
Affirmance.
I. BACKGROUND
A. Statutory and Regulatory Background
“To qualify for disability insurance benefits and supplemental security income under Titles
II and XVI of the [Social Security] Act, [a claimant] must establish that []he is ‘disabled.’” Butler
v. Barnhart, 353 F.3d 992, 997 (D.C. Cir. 2004). The Act considers a minor disabled if he “has a
medically determinable physical or mental impairment resulting in marked and severe functional
limitations” that is either fatal or will last for more than one year. 42 U.S.C. § 1382c(a)(3)(C)(i);
1 Pursuant to Rule 25(d) of the Federal Rules of Civil Procedure, Kililo Kijakazi, the acting director of the Social Security Administration, has been substituted for Andrew Saul as defendant. accord 20 C.F.R. § 416.906. A minor cannot be considered disabled if he “engages in substantial
gainful activity.” 42 U.S.C. § 1382c(a)(3)(C)(ii).
For child claimants, the Commissioner uses an “abbreviated version” of its normal five-
step process to determine whether the claimant is disabled. Sullivan v. Zebley, 493 U.S. 521, 526
(1990); see 20 C.F.R. § 416.924. First, the claimant must show that he is not “doing substantial
gainful activity.” 20 C.F.R. § 416.924(a), (b). Second, he must demonstrate that his impairment
is “severe,” as opposed to a “slight abnormality . . . that causes no more than minimal functional
limitations.” Id. § 416.924(a), (c). Third, the claimant must show that his impairments “meets,
medically equals, or functionally equals” one of the listings at 20 C.F.R. Part 404, Subpart P,
Appendix 1. Id. § 416.924(a), (d). If he does, and the impairment “meets the duration
requirement,” then the Commissioner will deem the child disabled. Id. § 416.924(d). But “[i]f a
child cannot qualify under these listings,” or his impairment does not meet the duration
requirement, then “he is denied benefits.” Zebley, 493 U.S. at 526. “There is no further inquiry
corresponding to the fourth and fifth steps of the adult test.” Id.
The listing relevant here is Listing 112.10, which describes autism spectrum disorder for
children aged three to eighteen. To meet or medically equal the severity of the impairment in the
listing, the child must show “[m]edical documentation of both . . . (1) [q]ualitative deficits in verbal
communication, nonverbal communication, and social interaction; and (2) [s]ignificantly
restricted, repetitive patterns of behavior, interests, or activities.” 20 C.F.R. pt. 404, subpt. P, app.
1, § 112.10 (emphasis omitted). In addition, the child must also establish “[e]xtreme limitation of
one, or marked limitation of two, of the following areas of mental functioning:
(1) Understand, remember, or apply information. (2) Interact with others. (3) Concentrate, persist, or maintain pace. (4) Adapt or manage oneself.”
2 Id. (citations omitted). To functionally equal the listing, the child must similarly show “‘marked
limitations’ in two . . . or an ‘extreme’ limitation in one” of the following domains:
(1) Acquiring and using information; (2) Attending and completing tasks; (3) Interacting and relating with others; (4) Moving about and manipulating objects; (5) Caring for [one]self; and (6) Health and physical well-being.
20 C.F.R. § 416.926a(a), (b)(1).
B. Factual Background
In K.J.’s early childhood, his mother became concerned about his delayed “speech and
language development.” A.R. 253. She brought him into Children’s National Health System for
an evaluation on October 23, 2018 (at one year, six months old). Id. At that visit, an evaluator
tested K.J.’s hearing, and his “[r]esults were consistent with normal hearing for at least part of the
speech frequency range in at least the better ear, if one exists.” Id. (quotation marks omitted). An
evaluator also administered the Receptive-Expressive Emergent Language Test (REEL-3) to test
K.J.’s receptive language, expressive language, and language ability. Id. at 254. K.J. scored below
the first percentile on all three. Id. K.J. would “not stop if someone call[ed] his name,” was “not
consistently responding to commands,” “d[id] not appear to understand the mood of others,”
reportedly understood only a handful of words, and could say only the word “mama.” Id. On
several of the indicators, including articulation, voice, and fluency, the evaluator wrote that K.J.
“could not be appropriately assessed . . . due to paucity of output.” Id. at 254–55.
Approximately one month later, on November 14, 2018 (at one year, seven months old),
K.J. had ear tubes placed in his ears due to recurring ear infections. See id. at 295. An evaluation
of K.J.’s hearing at a follow-up appointment showed “normal hearing in sound field testing,” and
his mother reported that she felt K.J.’s “hearing ha[d] improved.” Id.
3 A few months after the surgery, on January 7, 2019 (at one year, eight months old), K.J.
was given another standardized assessment called the Battelle Development Inventory-2 (BDI-2).
Id. at 272. K.J. again scored below the first percentile in both receptive communication and
expressive communication. Id. His overall communication score was in the 0.1st percentile and
indicated a sixty percent delay in communication skills. Id. at 272–73. At that point, while K.J.
sometimes (but not always) “respond[ed] to his name by looking up,” he did “not yet respond to
different tones [of] voices, pay attention to the conversations that go on around him, or follow
routine directions.” Id. at 272. He still did not use any words other than “mama.” Id. K.J. was
given an Individualized Family Service Plan that included weekly therapy with a speech and
language pathologist and an occupational therapist. Id. at 284, 286.
On March 20, 2019 (at one year, eleven months old), K.J. had another developmental
evaluation at Children’s National. Id. at 310. The doctors observed, among other things, that
K.J.’s “[r]eceptive language skills [we]re broadly delayed and presently appear to be slightly below
the [twelve]-month level,” and they described him as “nonverbal.” Id. at 312. The doctors
diagnosed K.J. with autism spectrum disorder. Id. at 313. In addition, they recommended that
K.J. continue to receive weekly speech and occupational therapy and add applied behavioral
analysis therapy, which would “have a direct and positive impact on [his] current functional skills
as well as his long-term prognosis.” Id.
On September 25, 2019 (at two years, five months old), K.J. was again evaluated at
Children’s National. Id. at 483. At that time, the doctor observed that K.J. had “made some
progress in the areas of language, socialization, and play skills.” Id. at 485. But the doctor noted
that K.J. “continue[d] to demonstrate problematic behaviors, some of which are quite dangerous
such as throwing himself down and running away from caregivers.” Id. K.J. was “consistently
4 using” only two words: “Mommy and blue,” and he was “not tuning into spoken language,” as he
responded to his name only half of the time and could not follow instructions. Id. at 484. The
doctor estimated that K.J.’s cognitive skills were now “at the [eighteen] to [twenty-one]-month
level, which illustrates an improvement of approximately [six] months in as many months.” Id. at
485. She recommended an increase in weekly therapy. Id.
On November 20, 2019 (at two years, seven months old), K.J. was again given the BDI-2
standardized evaluation. Id. at 453. He once again placed below the first percentile in both
receptive communication and expressive communication, and his skills were at an eight-month
and fourteen-month level, respectively. Id. at 454. Overall, his communication development was
in the 0.3rd percentile, and he exhibited a 64% developmental delay. Id. K.J. reportedly made
“intermittent[]” eye contact and was “beginning to respond to simultaneous verbal and gestural
commands,” but was not yet “looking around the room for” family members or objects when
named. Id. He could consistently say a few more words, including “hi,” “uh oh,” and “yay,” but
“primarily indicate[d] his wants and needs by crying.” Id. He was “not yet communicating in a
back-and-forth, turn-taking style or using more than [ten] words.” Id.
C. Procedural History
Ferguson filed a claim for Social Security benefits for K.J. on March 1, 2019. A.R. 152.
After K.J.’s claim was denied, she requested reconsideration and a hearing before an
Administrative Law Judge (ALJ). Id. at 30–50. On June 23, 2020, the ALJ denied K.J.’s
application, finding that he was not disabled under the Social Security Act. Id. at 13–24.
At step one of the disability evaluation process, the ALJ determined that K.J. had not
engaged in any substantial gainful activity. Id. at 17. At step two, he found that K.J. had the
5 following severe impairments: bilateral otitis media status post bilateral myringotomy; 2 delays in
receptive and expressive language, pragmatic language, and speech; upper respiratory infection;
asthma; autism spectrum disorder; and obesity. Id.
But the ALJ found that K.J.’s claim failed at step three, because his impairments or
combination thereof did not meet, medically equal, or functionally equal the severity of any listing,
including Listing 112.10 for autism spectrum disorder. Id. at 17–18 (citing 20 C.F.R. §§ 416.924,
925, 926). The ALJ first concluded that K.J.’s mental impairment did not meet or medically equal
the autism listing because his medical record did not show “extreme limitation of one, or marked
limitation of two, of the four areas of mental functioning” identified in the listing. Id. at 18. The
ALJ explained that while K.J. had a “marked limitation” in one domain (ability to interact with
others), he had a “less than marked limitation” in the other three areas. Id. The ALJ acknowledged
K.J.’s history of difficulty with language and social skills, but noted his improvement with therapy.
Id.
The ALJ further concluded that K.J.’s impairments did not functionally equal the severity
of the autism listing. Id. at 18–19. In making that determination, the ALJ considered all of the
evidence in the record, including K.J.’s medical records and Ferguson’s testimony, to evaluate
K.J.’s functioning on the six domains. Id. at 18–24. The ALJ again concluded that K.J. had a
“marked limitation” in only “interacting and relating with others,” while he had a “less than a
marked limitation” in the other five domains. Id. at 19–24. Because K.J. did not have “‘marked’
limitations in two domains of functioning or an ‘extreme’ limitation in one domain,” the ALJ found
2 This refers to K.J.’s ear infections and surgically-placed tubes. See Def.’s Mot. at 3, Dkt. 16; A.R. 591–92.
6 that his impairments did not functionally equal the listing. Id. at 24. As a result, the ALJ concluded
that K.J. was not disabled under the Social Security Act. Id.
The Appeals Council denied review of the ALJ’s decision on March 1, 2021. Id. at 1.
Ferguson subsequently brought this suit and moved for reversal of the ALJ’s decision. Pl.’s Mot.,
Dkt. 13.
II. LEGAL STANDARD
“In a disability proceeding, the ALJ ‘has the power and the duty to investigate fully all
matters in issue, and to develop the comprehensive record required for a fair determination of
disability.’” Simms v. Sullivan, 877 F.2d 1047, 1050 (D.C. Cir. 1989) (quoting Diabo v. Sec’y of
Health, Educ. & Welfare, 627 F.2d 278, 281 (D.C. Cir. 1980)). Once an ALJ issues a decision,
the claimant may seek review by the Administration’s Appeals Council. 20 C.F.R. § 416.1467. If
the Council denies review, the ALJ’s decision becomes the final decision of the Administration’s
Commissioner. See id. § 416.1481.
The Social Security Act gives federal district courts review over the Commissioner’s final
decisions. 42 U.S.C. §§ 405(g), 1383(c)(3). A reviewing court must affirm the Commissioner’s
decision if it is supported by substantial evidence, see id. § 405(g), and if it correctly applied the
relevant legal standards, Butler, 353 F.3d at 999. Substantial evidence is “such relevant evidence
as a reasonable mind might accept as adequate to support a conclusion.” Id. (quoting Richardson
v. Perales, 402 U.S. 389, 401 (1971)). This standard “requires more than a scintilla, but can be
satisfied by something less than a preponderance of the evidence.” Fla. Mun. Power Agency v.
FERC, 315 F.3d 362, 365–66 (D.C. Cir. 2003) (quotation marks and citation omitted).
“Substantial-evidence review is highly deferential to the agency fact-finder.” Rossello ex rel.
Rossello v. Astrue, 529 F.3d 1181, 1185 (D.C. Cir. 2008). On review, the “plaintiff bears the
7 burden of demonstrating that the Commissioner’s decision [was] not based on substantial evidence
or that incorrect legal standards were applied.” Settles v. Colvin, 121 F. Supp. 3d 163, 169 (D.D.C.
2015) (quoting Muldrow v. Astrue, No. 11-1385, 2012 WL 2877697, at *6 (D.D.C. July 11, 2012)).
Further, the reviewing court may not replace the ALJ’s judgment “concerning the credibility of
the evidence with its own.” Goodman v. Colvin, 233 F. Supp. 3d 88, 104 (D.D.C. 2017) (quotation
marks omitted). Rather, “[t]he credibility determination is solely within the realm of the ALJ.”
Grant v. Astrue, 857 F. Supp. 2d 146, 156 (D.D.C. 2012).
III. ANALYSIS
The ALJ concluded that K.J. did not meet, medically equal, or functionally equal the listing
for autism spectrum disorder in part because K.J. had only a marked limitation, not an extreme
limitation, in his ability to interact with others. That conclusion was not supported by substantial
evidence.
The “interact with others” domain in the autism listing considers a child’s ability to
communicate with language and make connections. See 20 C.F.R. pt. 404, subpt. P, app. 1,
§ 112.00(E)(2) (“Interact with others . . . refers to the abilities to relate to others age-appropriately
at home, at school, or in the community,” including “initiating or sustaining conversation” and
“understanding and responding to social cues”). The “interacting and relating with others”
domain, which is used to determine if a child functionally equals the listing, likewise measures a
child’s ability to “initiat[e] and respond[] to exchanges with other people, for practical or social
purposes.” 3 20 C.F.R. § 416a(i)(1)(i). In this domain, one- to three-year-old children should “be
3 The ALJ analyzed treated these two domains as the same, see A.R. 18 (discussion of the domain in listing cross-referencing discussion of the domain in the functional equivalence test), and so do both parties, see Pl.’s Mot. at 13; Def.’s Mot. at 9. The Court will do the same, and its conclusion accordingly implicates both the ALJ’s analysis of whether K.J. meets the autism listing and whether he functionally equals the listing.
8 able to express emotions and respond to the feelings of others,” “initiat[e] and maintain[]
interactions with adults,” “interact with other children [their] age,” and “communicate [their]
wishes or needs” through gestures and words. Id. § 416a(i)(2)(ii).
According to federal regulations, a child’s limitation is considered “marked” if he has
scores between two and three standard deviations below the mean on a “standardized test designed
to measure ability or functioning in that domain.” Id. § 416.926a(e)(2)(iii). The limitation is
considered “extreme” if the child’s scores are three standard deviations or more below the mean.
Id. § 416.926a(e)(3)(iii). In addition, for a child under the age of three where test scores are
unavailable, a limitation is “marked” if he functions at a level between one-half and two-thirds of
his age and “extreme” if he functions at a level one-half of his age or less. Id. § 416.926a(e)(2)(ii),
(e)(3)(ii). K.J.’s record includes multiple test scores and age-equivalency evaluations that support
a finding that he has an “extreme” limitation in his ability to interact with others.
The first such test was REEL-3, which K.J. took in October 2018. REEL-3 is a
standardized test that measures receptive language (including “comprehension skills and follow
through for directions”), expressive language, and “pragmatic (social) language skills for adult
interaction.” A.R. 254. Accordingly, it is designed to measure ability or functioning in the
“interact with others” domain. See 20 C.F.R. § 416a(i) (defining the domain to include language
skills). Because the mean REEL-3 score is one hundred with a standard deviation of fifteen, see
Pl.’s Mot. at 8 (citing Kenneth R. Bzoch et al., REEL-3 (3d ed. 1991)), scores of fifty-five or less
indicate an “extreme” limitation under the regulations. See 20 C.F.R. § 416.926a(e)(3)(iii). In
October 2018, K.J.’s language ability was forty-eight—far below that cut-off. A.R. 254. This
score indicates that in October 2018, K.J. had an extreme limitation in language ability.
9 Second, K.J. was evaluated using the BDI-2 in January 2019 (at one year, eight months
old). A.R. 272. The BDI-2 “is a standardized assessment battery for children” that measures
several things, including cognitive, communication, personal-social, motor, and adaptive skills.
A.R. 272, 272–74. The communication skills category thus corresponds to the “interacting with
others” domain. In that category, K.J.’s developmental quotient was fifty-five—in the 0.1st
percentile. Id. at 272–73. Under the regulations, such percentile scores “can be converted to
standard deviations” for the purposes of determining the extent of limitation. 20 C.F.R.
§ 416.926a(e)(1)(ii). In a normal distribution, a score at three standard deviations below the mean
corresponds to the 0.15th percentile. Barbara Illowsky & Susan Dean, Introductory Statistics,
§ 6.1 (2013), available at https://openstax.org/books/introductory-statistics/pages/6-1-the-
standardnormal-distribution. Thus, K.J.’s 0.1st-percentile communication score is “three standard
deviations or more below the mean.” 4 20 C.F.R. § 416.926(a)(e)(iii). Once again, this score shows
that according to the regulations, K.J.’s limitation in this domain was “extreme” in January 2019.
K.J.’s estimated age equivalency during that same evaluation leads to the same conclusion.
K.J. was twenty months old at the time, yet he had the receptive communication and expressive
communication skills of an eight-month-old (two-fifths of his actual age). A.R. 272. In addition,
the evaluator concluded that K.J.’s communication was 60% delayed, meaning he was functioning
at less than half (40%) of his age. Id. at 273. K.J.’s functioning “at a level one-half of his age or
less” indicates his communication limitation was “extreme” under the regulatory definition. 20
C.F.R. § 416.926a(e)(3)(ii).
4 This conclusion is confirmed by K.J.’s numerical score on this domain. Because “[t]he standard mean score on the BDI–2 is 100 with a standard deviation of 15,” Boyington ex rel. J.O.J.H. v. Colvin, 48 F. Supp. 3d 527, 531 (W.D.N.Y. 2014), K.J.’s score of fifty-five is three standard deviations below the mean. See A.R. 272–73.
10 Eleven months later, in November 2019, K.J. was again administered the BDI-2. A.R. 453.
At that time, his BDI-2 results for both receptive and expressive communication were below the
first percentile. Id. at 453–54. Although his overall communication development had marginally
improved to a score of fifty-eight (the 0.3rd percentile), the evaluator concluded that he now had
a 64% delay in communication skills development. Id. at 454. At thirty-one months old, K.J. was
displaying the receptive communication skills of an eight-month-old and the expressive
communication skills of a fourteen-month-old—both well below half his actual age. Id. at 453–
54.
While the ALJ noted the first two test scores, the ALJ did not consider the November 2019
evaluation, the most recent score. See id. at 20 (citing only the October 2018 REEL-3 and January
2019 BDI-2, but not the November 2019 BDI-2). This was reversible error, as the regulations
instruct the ALJ to consider K.J.’s November 2019 test score “together with the other information”
in the record. 20 C.F.R. § 416.926a(e)(4); see also 20 C.F.R. § 416.926a(e)(4)(iii)(B) (“When we
do not rely on test scores, we will explain our reasons for doing so in your case record or in our
decision.”). While K.J.’s score of fifty-eight (0.3rd percentile) on this test was not per se
“extreme” under the regulations, it was only “slightly higher than the level provided” in the
regulations for extreme limitations. 5 Id. § 416.926a(e)(4)(ii)(A). Thus, under the regulations, his
limitation might still be extreme “if other information in [his] case record shows that [his]
functioning in day-to-day activities is seriously or very seriously limited because of [his]
impairment(s).” Id.
5 Scores of seventy and below indicate “marked” limitations, while scores of fifty-five and below indicate “extreme” limitations. See Boyington, 48 F. Supp. 3d at 531. K.J.’s score was twelve points below the “marked” threshold, but only three points above the “extreme” threshold.
11 The November 2019 evaluation is directly relevant to the ALJ’s inquiry. It found that
K.J.’s communication showed, among other things, a “[s]ignificant [d]evelopmental [d]elay” and
that K.J. “[wa]s not yet communicating in a back-and-forth, turn-taking style or using more than
10 words.” A.R. 454. Moreover, the evaluation also reflected that K.J.’s communication skills
were extremely delayed compared to typical children his age. Most noteworthily, K.J.’s receptive
communication functioning was almost one-quarter of his actual chronological age—far below
the regulation’s cut-off for extreme limitations. Id.; see also id. (also noting that K.J.’s expressive
communication functioning was 45% and overall communication was 60% of actual age); 20
C.F.R. § 416.926a(e)(3)(ii) (explaining that functioning at less than half of one’s actual age is an
“extreme” limitation). While these age equivalency metrics are not dispositive because K.J. also
had a standardized test score in his record, see 20 C.F.R. § 416.926a(e)(3)(ii), they constitute
“other evidence [that] shows that [K.J.’s] impairment(s) cause[d] [him] to function in school,
home, and the community far below [his] expected level of functioning.” Id.
§ 416.926a(e)(4)(ii)(A). And they would help the ALJ “compare [K.J.’s] functioning to the typical
functioning of children [his] age who do not have impairments,” as is required in the evaluation of
each domain. Id. § 416.926a(f)(1). But the ALJ did not consider them at all.
Indeed, the ALJ’s failure to consider the November 2019 evaluation was material, because
doing so would have directly undermined his reasoning for why K.J.’s limitation was only marked.
The ALJ reasoned that since the October 2018 and January 2019 tests, K.J. had received ear
surgery and began weekly therapy—and after those two interventions, K.J. “made some progress
in the areas of language, socialization, and play skills.” A.R. 20–21 (citing the September 2019
follow-up evaluation, see id. at 485). Because of this progress, the ALJ concluded that the earlier
scores did not compel finding an “extreme” limitation, despite falling in the regulations’ range for
12 “extreme.” Id. at 18, 20–21. But the November 2019 score squarely calls that conclusion into
question. In November 2019—over one year after his first test score in the “extreme” category,
and just one month after some noted progress—K.J. was still scoring in the less-than-first
percentile on standardized tests for communication. See id. at 454. At the same time, K.J.’s
communication skills had worsened four percentage points since the January 2019 evaluation. See
id. at 272–73, 454.
In sum, the ALJ did not “analyze[] all evidence” relevant to the interacting with others
domain. See Goodman, 233 F. Supp. 3d at 104. His omission was more than harmless error
because the evidence he failed to consider undermines his conclusion; indeed, it flatly contradicts
the reasoning he provided to explain why K.J.’s limitation was not extreme. See Bethel o/b/o C.B.
v. Berryhill, No. 18-cv-00247, 2019 WL 12251881, at *11 (D.D.C. Aug. 29, 2019) (“An ALJ may
not simply ignore evidence in the record that might undercut his ultimate conclusion.”), report and
recommendation adopted, 2019 WL 12251879 (D.D.C. Oct. 2, 2019). Because a finding that K.J.
had an “extreme” limitation in one domain would be sufficient to conclude that K.J. met, medically
equaled, or functionally equaled the listing, 20 C.F.R. pt. 404, subpt. P, app. 1, § 112.10; 20 C.F.R.
§ 416.926a(a), (b)(1), the ALJ’s determination will be reversed and remanded. 6
Turning to relief, Ferguson asks the Court to order the ALJ to award benefits to K.J. Pl.’s
Mot. at 14–15. Although the Court agrees that the ALJ’s opinion ignored relevant evidence, that
evidence does not “clearly indicat[e]” that K.J. had a disability so as to warrant such an order.
Espinosa v. Colvin, 953 F. Supp. 2d 25, 36 (D.D.C. 2013). The Court will instead remand the case
to the ALJ to reconsider his determination, giving proper consideration to the evidence in the

13 record, including the November 2019 BDI-2 standardized evaluation, in the “interacting with
others” domain.
CONCLUSION
For the foregoing reasons, the Court grants the plaintiff’s Motion for Judgment of Reversal
and denies the defendant’s Motion for Judgment of Affirmance. A separate order consistent with
this decision accompanies this memorandum opinion.
