The opinion of the court was delivered by
Jacobs, J.
The petitioners appealed under R. R. 4:88-8 from a decision of the State Board of Education affirming a decision of the Commissioner of Education. We certified om our own motion before argument in the Appellate Division,
After receiving protests against the racial imbalance in thePlainfield public school system, the local Board of Education appointed a lay advisory committee to review the matter and! submit its report. The committee recommended that Dr. Max Wolff of New York City be retained and in April 1962 the local Board entered into an agreement which provided that Dr. Wolff, working with a team of specialists in the areas of education, sociology, psychology and zoning, would conduct a study of the racial composition of the schools and would submit findings, conclusions and suggestions by June 15, 1962, [164]*164In due time, Dr. Wolff submitted his report and recommendations to the lay advisory committee which approved, in principle, the procedure and fact-findings of the specialists team but failed to agree on recommendations and, in turn, submitted majority and minority reports of its own to the local Board.
As indicated in Dr. Wolff’s report, the Negro pupil population of the elementary schools1 in Plainfield was 37 per cent in April 1962. At that time the Negro population of the Washington School was over 95 per cent; in the other elementary schools it ranged between 0 and 65 per cent, with the Emerson, Stillman, Bryant and Lincoln schools having well over 50 per cent. Dr. Wolff submitted two plans designed to reduce racial imbalance. Plan I involved a general rezoning from north-south, instead of the then current practice of east-west; this would integrate the predominantly Negro northern area of the community with the predominantly white southern area. ’See Sedler, “School Segregation in the North and West: Legal Aspects,” 7 St. Louis U. L. J. 228, 253. (1962). Plan II, which was submitted as an alternate and preferred plan, involved the pairing of six schools into three separate sets of schools in line with what has generally become known as the Princeton plan. See Addabbo v. Donovan, 22 A. D. 2d 383, 256 N. Y. S. 2d 178 (1965).
In July 1962 the local Board declined to adopt either of the plans submitted by Dr. Wolff and issued a statement embodying its reasons. During the same month, it announced an optional pupil registration plan for the school year commencing September 1962. Under this plan, pupils could voluntarily transfer to schools outside their residence areas provided acceptable class sizes were not exceeded and provided further that parents supplied any necessary transportation. Only 69 pupils transferred under this plan. In September 1962 the petitioners, who are children enrolled in the Plain-[165]*165field school system and are acting through their parents or other legal representatives, filed a petition with the Commissioner of Education, protesting the local Board’s refusal to adopt plans and procedures which would eliminate “racial segregation in the public schools” and “the denial of equal educational opportunities” to the petitioners and others similarly situated. An answer to the petition was duly filed and a stipulation of issues and facts was entered into in June 1963.
In the stipulation, the petitioners acknowledged that there was no issue of “intentional or deliberate segregation of elementary school pupils”; they asserted, however, that the maintenance of predominantly Negro schools engendered feelings and attitudes which tended to interfere with successful learning and tended to produce in the minds of Negro pupils “a sense of stigma and a feeling of inferiority” which had an undesirable effect upon their attitudes in education; they asserted, further, that the optional pupil registration plan did not meet or relieve the problem of racial imbalance and urged that the Commissioner approve either plan recommended by Dr. Wolff.
The stipulation set forth the local Board’s position that the elementary school attendance areas in Plainfield were set up on sound educational principles and that it had no duty to alter the areas “for the sole purpose of maintaining any particular percentage of pupil distribution by color or race.” It then went on to state that if the Commissioner should determine that there was racial imbalance which should be eliminated in the Plainfield schools or in any of them, then the Commissioner should approve a plan which the local Board had prepared under the designation “Sixth Grade Plan” and which it offered to put into effect by September 1963. Under this plan all sixth grades would be placed in the Washington School and “all„K-5 grades in Washington School” would be transferred to other schools determined by the local Board’s administrative staff on the basis of availability and utilization of classrooms; bus transportation [166]*166would be provided for all pupils who are transferred out of their original school zones irrespective of distance; and no pupils would be transferred to any school where the Negro enrollment was over 50 per cent.
No oral testimony was taken before the Commissioner who dealt with the matter on the basis of the record before him which included the petition, the answer and the stipulated issues and facts. Between the submission of Dr. Wolff’s report in June 1962 and the Commissioner’s decision in June 1963, the racial imbalance in some of the Plainfield schools had intensified. Thus as of April 1963, the Negro pupil population in the Washington School had risen to 96.2 per cent, in Emerson to 72.1 per cent, in Stillman to 67.6 per cent, in Bryant to 65.5 per cent and in Clinton to 58.9 per cent. The remaining elementary schools, apart from the Lincoln School which is a special school for retarded children, varied between 0.6 per cent and 44.9 per cent. The Negro pupil population in the entire elementary school system had risen to 40.4 per cent (as of April 1964 it had risen to 44.7 per cent and as of October 1964 to 47.3 per cent).
In his decision, the Commissioner first noted that there was no issue of deliberate segregation before him and that the cause of the concentration of the Negro population in particular schools was to be found in patterns of housing resulting from “a constellation of socio-economic factors.” He then went on to point out that even though that be so the local Board was not thereby relieved of its responsibility to take whatever reasonable and practicable steps were available to it "to eliminate, or at least mitigate, conditions which have an adverse effect upon its pupils.” Quoting from his own opinion in Fisher v. Board of Education of the City of Orange (decided May 15, 1963) he said:
“[T]he Commissioner is of the opinion that in the minds of Negro pupils and parents a stigma is attached to attending a school whose enrollment is completely or almost exclusively Negro, and that this sense of stigma and resulting feeling of inferiority have an undesirable effect upon attitudes related to successful learning. Reasoning from [167]*167this premise and recognizing the right of every child to equal educational opportunity, the Commissioner is convinced that in developing its pupil assignment policies and in planning for now school buildings, a board of education must take into account the continued existence or potential creation of a school populated entirely, or nearly so, by Negro pupils.”
The Commissioner found from Plainfield’s enrollment table that the Washington School was the only one where the enrollment was “almost entirely” Negro. He stated that he had given careful consideration to the two plans submitted by Dr. Wolff and the Sixth Grade Plan submitted by the local Board, that under each of the plans there would be no “all or nearly all” Negro school, and that “each plan is reasonable, practicable, and consistent with sound educational practice.” He expressed the belief that it was the responsibility and prerogative of the local Board to determine which plan was best suited to the needs of the school system and he directed that the local Board select one of the three plans and put it into effect for the 1963-1964 school year. On the day following the 'Commissioner’s decision the local Board put its own Sixth Grade Plan into operation.
The petitioners then appealed to the State Board of Education which heard argument in November 1963. In the meantime, and after the operation of the Sixth Grade Plan had become effective, there were shifts of Negro pupil population. As of October 1963 the Negro pupil population in Washington School was reduced to 36.6 per cent but Emerson rose from 72.1 per cent to 76.4 per cent, Bryant from 65.5 per cent to 67.1 per cent and Clinton from 58.9 per cent to 66.1 per cent. Stillman dropped somewhat from 67.6 per cent to 65.2 per cent. (As of October 1964, Bryant had risen to 78.6 per cent and Clinton had risen to 71.3 per cent whereas Emerson and Stillman had dropped insignificantly to 75.7 per cent and 65 per cent respectively.) The Jefferson School which in 1962 had a Negro pupil population of 44.9 per cent rose to 52.1 per cent in October 1963 and to 56.6 per cent in October 1964.
[168]*168In affirming the Commissioner’s decision, the State Board of Education stressed the Commissioner’s language relating to schools which were almost entirety Negro and to his corrective action with respect to the Washington School. It took the position that the crucial question was not mathematical imbalance but whether the school fell within the Commissioner’s test of “completely or almost entirety Negro”; and it concluded that within this test the Emerson, Bryant, Clinton, Stillman and Jefferson schools were free from attack. It expressed the view that racial imbalance was not to be equated with invidious segregation as condemned by the Commissioner and by the State Board itself in Volpe v. The Board of Education of the City of Englewood (decided September 25, 1963). It found that there had been no showing “that the ‘imbalance’ resulting from the adoption of the ‘Sixth Grade Plan’ ” had deprived the Negro pupils of equal educational opportunities and that its adoption by the local Board and its approval by the Commissioner should be sustained. In support of their appeal from the State Board’s decision, the petitioners urge before us that under both federal and state law there was a duty to eliminate racial imbalance beyond the step which was taken by the local Board to correct the situation at the Washington School and which was sustained by the Commissioner and the State Board.
When in Brown v. Board of Education of Topeka, 374 U. S. 483, 74 S. Ct. 686, 98 L. Ed. 873 (1954), the Supreme Court struck down segregated schools, it recognized that they generate a feeling of racial inferiority and result in a denial of equal educational opportunities to the Negro children who must attend them. Although such feeling and denial may appear in intensified form when segregation represents official policy, they also appear when segregation in fact, though not official policy, results from long standing housing and economic discrimination and the rigid application of neighborhood school districting. Brown itself did not, of course, deal with the latter or de facto type of segregation and federal judges have differed as to whether that situation gives rise to [169]*169an affirmative duty under the Fourteenth Amendment to take suitable action. Compare Bell v. School City of Gary, Indiana, 213 F. Supp. 819 (N.D.Ind. 1963), aff'd 324 F. 2d 209 (7 Cir.), cert. denied 377 U. S. 924, 84 S. Ct. 1223, 12 L. Ed. 2d 216 (1964); Downs v. Board of Education of Kansas City, Kansas, 336 F. 2d 988, 998 (10 Cir. 1964), cert. denied 380 U. S. 914, 85 S. Ct. 898, 13 L. Ed. 2d 800 (1965), with Barksdale v. Springfield School Committee, 237 F. Supp. 543 (D. Mass. 1965); Blocker v. Board of Education of Manhasset, New York, 226 F. Supp. 208 (E. D. N. Y. 1964). See Kaplan, “Segregation Litigation and the Schools—Part II: The General Northern Problems,” 58 Nw. U. L. Rev. 157, 170 (1963); Sedler, supra, 7 St. Louis U. L. J., at p. 250.
In Bell, the court found that there was no official policy of segregation and that the Gary School Board had consistently required students to attend their neighborhood schools without regard to race; on that finding it concluded that the board was under no obligation under the federal constitution to take any steps towards integration of the school population or towards correction of the racial imbalance which existed in the Gary school system. See Kaplan, “Segregation Litigation and the Schools—Part III: The Gary Litigation,” 59 Nw. U. L. Rev. 121 (1964). The decision in Bell may be contrasted with the recent decision in Barksdale. There an action was brought for a declaration that the Springfield School Committee had denied to the plaintiffs their rights under the Fourteenth Amendment by assigning them to racially segregated schools. The court found that there was no deliberate intent on the part of the school authorities to segregate the races, and that such segregation as did exist resulted from rigid adherence to the neighborhood plan of school attendance. But it also found that, although the Negro elementary school population was 17.4 per cent, there were schools with Negro population appreciably more than 50 per cent (e.g., 59 per cent, 62.9 per cent, 75.3 per cent, 89.9 per cent), that the ability of Negro children to obtain equal educational opportu[170]*170nities in such racially imbalanced schools was impaired, and that the local School Committee was under an affirmative obligation under the Fourteenth Amendment to eliminate racial concentration “to the fullest extent possible” within the framework of effective educational procedures. With reference to the holding in Bell, it had this to say:
“The defendants argue, nevertheless, that there is no constitutional mandate to remedy racial imbalance. Bell v. School City of Gary Indiana, 324 F. 2d 209 (7th Cir. 1963). But that is not the question. The question is whether there is a constitutional duty to provide equal educational opportunities for all children within the system. While Brown answered that question affirmatively in the context of coerced segregation, the constitutional fact — the inadequacy of segregated education' — -is the same in this case, and I so find. It is neither just nor sensible to proscribe segregation having its basis in affirmative state action while at the same time failing to provide a remedy for segregation which grows out of discrimination in housing, or other economic or social factors. Education is tax supported and compulsory, and public school educators, therefore, must deal with inadequacies within the educational system as they arise, and it matters not that the inadequacies are not of their making. This is not to imply that the neighborhood school policy per se is unconstitutional, but that it must be abandoned or modified when it results in segregation in fact.” 237 F. Supp., at p. 546.
See Fiss, “Racial Imbalance in the Public Schools: The Constitutional Concepts,” 78 Harv. L. Rev. 564, 583 (1965).
Whether or not the federal constitution compels action to eliminate or reduce de facto segregation in the public schools, it does not preclude such action by state school authorities in furtherance of state law and state educational policies. See Morean v. Bd. of Ed. Town of Montclair, 42 N. J. 237, 242-244 (1964); Addabbo v. Donovan, supra, 256 N. Y. S. 2d, at pp. 182-184; cf. Schults v. Bd. of Ed. of Township of Teaneck, 86 N. J. Super. 29 (App. Div. 1964), aff'd 45 N. J. 2 (1965). In a society such as ours, it is not enough that the 3 R’s are being taught properly for there are other vital considerations. The children must learn to respect and live with one another in multi-racial and multi-cultural communities and the earlier they do so the better. It is during their formative school years that firm foundations may be [171]*171laid for good citizenship and broad participation in the mainstream of affairs. Recognizing this, leading educators stress the democratic and educational advantages of heterogeneous student populations and point to the disadvantages of homogeneous student populations, particularly when they are composed of a racial minority whose separation generates feelings of inferiority. It may well be, as has been suggested, that when current attacks against housing and economic discriminations bear fruition, strict neighborhood school districting will present no problem. But in the meantime the states may not justly deprive the oncoming generation of the educational advantages which are its due, and indeed, as a nation, we cannot afford standing by. It is heartening to note that, without awaiting further Supreme Court pronouncements, some states, including our own, have taken significant legislative or administrative steps towards the elimination or reduction of de facto segregation. See Report of the United States Commission on Civil Rights 1968, pp. 55-62.
The California State Board of Education has adopted regulations designed to avoid attendance areas which “in practical effect” discriminate upon an ethnic basis or tend to establish or maintain segregation on an ethnic basis. These regulations were cited by the California Supreme Court in Jackson v. Pasadena City School District, 59 Cal. 2d 876, 31 Cal. Rptr. 606, 382 P. 2d 878 (1963), where a Negro student brought an action seeking a transfer from his predominantly Negro neighborhood school to a predominantly white school. While its actual holding was narrower, the court’s opinion clearly recognized that, under state law and policy, the school authorities have an affirmative duty to take steps towards alleviation of racial imbalance in the school system without regard to its origin. Speaking for all members of the court, Chief Justice Gibson said:
“So long as large numbers of Negroes live in segregated areas, school authorities will be confronted with difficult problems in providing Negro children with the kind of education they are entitled to have. Residential segregation is in itself an evil which tends to [172]*172frustrate tke youth in the area and to cause antisocial attitudes and behavior. Where such segregation exists it is not enough for a school board to refrain from affirmative discriminatory conduct. The harmful influence on the children will bo reflected and intensified in the classroom if school attendance is determined on a geographic basis without corrective measures. The right to an equal opportunity for education and the harmful consequences of segregation require that school boards take steps, insofar as reasonably feasible, to alleviate racial imbalance in schools regardless of its cause.” 382 P. 2d, at pp. 881-882.
See Note, “California Suggests De Facto School Segregation Must End,” 16 Stan. L. Rev. 434 (1964); Note, “Schools and School Districts: Alleviation of Racial Imbalance,” 51 Calif. L. Rev. 810 (1963).
New York’s Board of Regents has issued statements of policy recognizing the insufficiency of public education in schools where segregation in fact exists and its State Commissioner has taken affirmative action towards elimination of racial imbalance wherever reasonably feasible. In a communication addressed to all local school administrators and boards, the Commissioner advised that the State Education Department’s position was that racial imbalance in predominantly Negro schools “interferes with the achievement of equality of educational opportunity” and must be eliminated, and he requested that individual reports be submitted by school districts with respect to their racially imbalanced schools and the corrective steps being taken. (For the purposes of these reports the Commissioner defined a racially imbalanced school as “one having 50 per cent or more Negro pupils enrolled.”) The broad scope of the supervisory powers vested in the Commissioner and the forthright manner of their exercise are well illustrated by the recent litigation in Vetere v. Allen, 41 Misc. 2d 200, 245 N. Y. S. 2d 682 (Sup. Ct. 1963), modified Vetere v. Mitchell, 21 A. D. 2d 561, 251 N. Y. S. 2d 480 (1964), aff’d Vetere v. Allen, 15 N. Y. 2d 259, 258 N. Y. S. 2d 77, 206 N. E. 2d 174 (1965), petition for cert. filed 33 U. S. L. Week 3412 (June 22, 1965).
In Velere the school district had three elementary schools. As a result of the concentration of Negroes in a specific area [173]*173of the community, the Woodfield School had a Negro pupil population, of 75 per cent whereas in each of the other two schools it was 14 per cent. The local board refused to take any corrective action and several Negro children appealed through their parents to the Commissioner. The Commissioner heard oral argument, received recommendations from his Advisory Committee on Human Relations and Community Tensions, and directed the local board to adopt a plan prepared by the Committee and approved by the Commissioner. Thereafter the local board submitted a proposed plan but it was rejected by the Commissioner who ordered the effectuation of his own plan which called for the attendance of all fourth and fifth grade pupils at the Woodfield School and all lower grade pupils at the other schools. On appeal, a trial judge annulled the Commissioner’s order but this action was vacated by the Appellate Division which found that there was support in the record for the Advisory Committee’s recommendation and the Commissioner’s determination, that the Commissioner’s decision was neither arbitrary nor capricious, and that the court could not "substitute some other judgment for the judgment of the Commissioner that correction of racial imbalance is an educational aid to a minority group in attaining the skills and level of education which others have had for generations and that compulsory education should be designed for the greatest good of all.” 251 N. Y. S. 2d, at pp. 483-484. On further appeal, the New York Court of Appeals affirmed the Appellate Division, holding that the Commissioner’s decision, based on the finding that correction of racial imbalance was essential to sound education, was not arbitrary or illegal. See Board of Education of City of New York v. Allen, 6 N. Y. 2d 127, 188 N. Y. S. 2d 515, 160 N. E. 2d 60 (Ct. App. 1959); Van Blerkom v. Donovan, 15 N. Y. 2d 399, 259 N. Y. S. 2d 825, 207 N. E. 2d 503 (Ct. App. 1965).
Our own State’s policy against racial discrimination and segregation in the public schools has been long standing and vigorous, and our Commissioner of Education has been [174]*174vested with broad power to deal with the subject; indeed, his power in this regard may fairly be viewed as no less comprehensive in nature than that possessed by New York’s Commissioner and exercised by him in Vetere. Cf. Blumrosen, Securing Equality: The Operation of the Laws of New Jersey Concerning Racial Discrimination, 71 et seq. (1964); Blumrosen, “Anti-discrimination Laws in Action in New Jersey: A Law-Sociology Study,” 19 Rutgers L. Rev. 189, 261 (1965). As early as 1881 there was legislation in New Jersey declaring it unlawful to exclude a child from any public school because of his race (L. 1881, c. 149) and this appears in broadened form in our current statutes. N. J. S. A. 18:14-2. When called upon, our courts have not hesitated to strike down direct and indirect efforts to circumvent the legislative direction. See Pierce v. Union District School Trustees, 46 N. J. L. 76 (Sup. Ct. 1884), aff’d 47 N. J. L. 348 (E. & A. 1885); Raison v. Bd. of Education, Berkeley, 103 N. J. L. 547 (Sup. Ct. 1927); Patterson v. Board of Education, 11 N. J. Misc. 179, 164 A. 892 (Sup. Ct. 1933), aff’d 112 N. J. L. 99 (E. & A. 1934); Hedgepeth v. Board of Education of City of Trenton, 131 N. J. L. 153 (Sup. Ct. 1944).
New Jersey’s strong policy against racial discrimination and segregation in the public schools finds further expression in Article 1, paragraph 5 of the 1947 Constitution which provides that “[n]o person shall be denied the enjoyment of any civil or military right, nor be discriminated against in the exercise of any civil or military right, * * * nor be segregated in the militia or in the public schools, because of religious principles, race, color, ancestry or national origin.” In 1949 the Legislature broadened its earlier law against discrimination (L. 1945, c. 169) to embody provisions against discrimination in places of public accommodation. L. 1949, c. 11. See Levitt & Sons, Inc. v. Div. Against Discrimination, etc., 31 N. J. 514, appeal dismissed, 363 U. S. 418, 80 S. Ct. 1257, 4 L. Ed. 2d 1515 (1960); Jones v. Haridor Realty Corp., 37 N. J. 384 (1962). As thus broadened, the law provides that all persons shall have the opportunity to obtain [175]*175“all the accommodations, advantages, facilities, and privileges of any place of public accommodation,” including any public school, “without discrimination because of race.” N. J. S. A. 18:25-4; N. J. S. A. 18:25-5. In Walker v. Board of Education of the City of Englewood (decided May 19, 1955), the Attorney General advanced the contention before the Commissioner of Education that this law, in itself, precluded a board of education “from permitting the existence of segregation— in fact” when it could reasonably be eliminated. See Greenberg, Race Relations and American Law 251 (1959). The Commissioner, while expressing his full awareness of Broion and its holding that school segregation on the basis of race deprives the minority children of “equal educational opportunities,” did not pass on this contention although he did direct the Englewood Board to draw new boundary lines and to eliminate a school which he found to be maintained in “violation of the law against discrimination.’3
In a series of cases commencing with Fisher v. Board of Education of the City of Orange, supra, the Commissi oner has dealt with attacks on de facto school segregation which came before him in proceedings under R. S. 18:3-14. That statute provides that the Commissioner shall decide all controversies and disputes under the school laws or under the rules and regulations of the State Board or of the Commissioner. Its comprehensive terms were liberally implemented by the opinions of this Court in Laba v. Newark Board of Education, 23 N. J. 364, 381-384 (1957), and In re Masiello, 25 N. J. 590, 605-607 (1958), where we stressed the Commissioner’s overriding responsibility “to make certain that the terms and policies of the School Laws are being faithfully effectuated.”
In Fisher it appeared that the pupil enrollment in Orange was 50 per cent white and 50 per cent Negro and that enrollment in the Oalcwood 'School was 99 per cent Negro. The Commissioner, although he found that the- Oakwood segregation resulted from housing problems rather than from official policy, determined (1) that attendance at the Oalcwood School engendered feelings and attitudes “which tend to interfere [176]*176with successful learning,” (2) that such extreme imbalance as obtained at Oakwood constituted under New Jersey law “a deprivation of educational opportunity for the pupils compelled to attend the school,” and (3) that reasonable means “consistent with sound educational and administrative practice” existed and must be taken to avoid the concentration of Negro pupils at the Oakwood School.
In Spruill v. Board of Education of the City of Englewood (decided July 1, 1963), it appeared that the Negro pupil population of Englewood was 39.1 per cent and that the Negro population at the Lincoln School was 98 per cent. The Commissioner found that there had not been any showing of deliberate intent by the school board to segregate but held nevertheless that the Lincoln School must be desegregated under the principles expressed by him in Fisher. In the course of his opinion he pointed to the advantages which ordinarily accompany the neighborhood school policy but then went on to state that “the assignment of pupils to nearby schools is a general principle and is not to be applied inflexibly when other considerations outweigh its values.” He did not prescribe any plan of his own for reducing the racial imbalance in the Lincoln School but noted instead that several plans had been proposed and that the local board was the one charged with the formulation of the most suitable plan; in this connection, he quoted from and relied upon his own opinion in the Booker case, now before us. See Fuller v. Volk, 230 F. Supp. 25 (D. N. J. 1964).
In Alston v. The Board of Education of the Township of Union (decided April 6, 1964), the local board adopted a voluntary optional pupil transfer policy for the regular pupils of the Jefferson School which had a 95 per cent Negro enrollment in a community having a 10 per cent Negro school population. The petitioners contended that the board’s plan was inadequate and they requested that the Commissioner formulate a plan of his own. In dismissing the petition without prejudice to its renewal at a later date, the Commissioner rejected the contention that the local board’s plan was ineffec[177]*177tive, pointing out that it had not been given a fair trial and that he could not indulge in any presumption that it would fail to achieve its purpose. In discussing the request that he formulate his own plan, he stated that the choice among the various solutions proposed should be made “in the first instance” by the local board and that on appeal he must “keep within proper limits of judicial inquiry.” In elaboration of this latter thought, the Commissioner quoted from Boult v. Board of Education of Passaic (decided January 8, 1946), aff’d 135 N. J. L. 329 (Sup. Ct. 1947), aff’d 136 N. J. L. 521 (E. & A. 1948), where one of his predecessors had expressed the view that it was “not a proper exercise of a judicial function for the Commissioner to interfere with local boards in the management of their schools unless they violate the law, act in bad faith (meaning acting dishonestly), or abuse their discretion in a shocking manner.”
Boult dealt with a local board’s power to discontinue a school and had no relation to segregation or race. However, the Commissioner’s quotation of its language would indicate that his position as to the scope of his authority and responsibility when passing on local steps towards desgregration is too restrictive and not fully compatible with our decision in In re Masiello, supra, 25 N. J. 590. In Masiello the Commissioner took the view that when reviewing action of the Board of Examiners his function is simply to determine whether its action was “arbitrary or capricious or whether it was the result of bias or prejudice.” 25 N. J., at p. 605. We rejected this view, pointing out that under R. S. 18:3-14 the Commissioner is to decide all controversies and disputes arising under the school laws or under the rules of the State Board or of the Commissioner, and that this involves a responsibility on his part to make independent determinations, giving due weight, of course, to the findings and actions and the measure of discretion vested below. 25 N. J., at p. 606; cf. Kopera v. West Orange Bd. of Education, 60 N. J. Super. 288, 295-297 (App. Div. 1960). None of this brings into question the Commissioner’s policy, as expressed in Alston, [178]*178of leaving to the local board the choice in the first instance among the various solutions proposed towards the elimination of de facto school segregation. But it does mean that when the sufficiency of the local choice is brought before him he must affirmatively determine whether the reasonably feasible steps towards desegregation are being taken in proper fulfillment of State policy; if not, he may remand the matter to the local board for further action or may prescribe a plan of his own as was done in Velere. Cf. Laba v. Newark Board of Education, supra, 23 N. J., at pp. 381-384.
In one additional respect the Commissioner, along with the State Board in sustaining his pertinent determinations, has taken a position which we deem too restrictive. While he has broadly recognized and acted on the principle that de facto segregation has an undesirable effect upon attitudes related to successful learning and denies equal educational opportunities to the racial minority, he has narrowly confined relief to situations where the schools in question were entirely or almost entirely Negro. This may be contrasted with Vetere where the Commissioner ordered the desegregation of a school with 75 per cent Negro pupil population, with Barksdale where the court ordered the desegregation of schools with Negro pupil populations appreciably more than 50 per cent but less in substantially varying amounts than 90 per cent, and with the general tenor of our own opinion in Morean v. Bd. of Ed. of Montclair, supra. In Korean we first noted that an official policy of segregation would not be consistent either with sound legal principles or sound educational policies and then pointed to the fact that racial imbalance, though fortuitous in origin, presents much the same disadvantages as are presented by segregated schools. 42 N. J., at pp. 242-243. While we there made no attempt to define the precise extent of racial imbalance which would require remedial action, we did refer approvingly to Jackson v. Pasadena City School District, supra, where the court, after indicating that substantial racial imbalance would call for relief, cautioned that exact apportionment of Negroes among the [179]*179schools was not required and that consideration must be given to all relevant factors “including the practical necessities of governmental operation.” 382 P. 2d, at p. 882
In the case at hand, Dr. Wolff acknowledged that there was no fixed racial composition that students of the subject considered ideal for all communities and he suggested that a desirable distribution of white and Negro children would be a range of one-third greater or less than the percentage of Negro pupils to white pupils in the whole elementary school system. In Bell v. School City of Gary, Indiana, supra, District Judge Beamer said that this might be a good sociological definition but that there was no support for it as a legal definition. 213 F. Supp., at 829. In Barksdale Chief Judge Sweeney made the finding that in the light of the relation of white to non-white in the City of Springfield, “a non-white attendance of appreciably more than fifty per cent in any one school is tantamount to segregation.” 237 F. Supp., at p. 544. Elsewhere racially imbalanced schools have been described as those predominantly or substantially Negro in view of the ratio throughout the school system;2 and, occasionally, fixed percentages in varying amounts have been urged. See Kaplan, supra, 58 Nw. U. L. Rev., at p. 181; Fiss, supra, 78 Harv. L. Rev., at p. 579. Before us, the petitioners have not advanced any fixed percentage but have presented the thought that, at some ascertainable point, the Negro population of a school becomes so excessively high, in contrast to the percentage of Negroes in the schools of the same level in the community, that it becomes known as a Negro school with the attendant “sense of stigma and resulting feeling of inferiority” referred [180]*180to in Fisher v. Board of Education of the City of Orange, supra. That point generally may be well above 50 per cent but well below the Commissioner’s and State Board’s 100 per cent or nearly 100 per cent, as evidenced by the racially imbalanced schools stricken in Vetere and Barksdale.
As in Vetere and Barksdale, the goal here is a reasonable plan achieving the greatest dispersal consistent with sound educational values and procedures. This brings into play numerous factors to be conscientiously weighed by the school authorities. Considerations of safety, convenience, time economy and the other acknowledged virtues of the neighborr hood policy must be borne in mind. Costs and other practicalities must be considered and satisfied. And trends towards withdrawal from the school community by members of the majority must be viewed and combatted, for if they are not, the results may be as frustrating as the inaction complained about by the minority. In his report, Dr. Wolff enumerated the advantages and disadvantages of both of his plans which were aimed at correcting racial imbalance throughout the entire elementary school system while preserving, wherever possible, the neighborhood policy. Both plans contemplated the closing of the Bryant School which was described as “the oldest, least efficient and most expensive school in the city.” As outlined by Dr. Wolff, the advantages of each plan were substantial whereas its disadvantages were insubstantial and the Commissioner acknowledged that each of the plans was reasonable, practicable and consistent with sound educational practice. He nonetheless sanctioned their rejection and permitted the local Board to put into effect its own Sixth Grade Plan which he also found to be a proper one. But that plan, while it had the highly desirable effect of integrating the Washington School, was not pointed towards the goal of greatest dispersal in the school system as a whole and did nothing helpful towards meeting the racial imbalance at schools such as Bryant which, as of October 1964, had a Negro pupil population of 78.6 per cent. It appears evident to us that in granting approval of the Sixth Grade Plan with[181]*181out more, the Commissioner was misled by unduly restrictive views, hereinbefore indicated, (1) as to the scope of his own functions in reviewing and supervising local actions, and (2) as to his own responsibilities in the correction of substantial racial imbalance which may be educationally harmful though it has not reached the standard of “all or nearly all Negro.”
At oral argument it was indicated that further steps towards correcting the racial imbalance in the elementary schools of Plainfield were now being considered by the local Board. Respondent’s counsel stressed that the responsibility for maintaining a sound educational system rests primarily with the school authorities and he urged that the decision of the Commissioner and the State Board, sustaining the local Board’s Sixth Grade Plan, not be disturbed. The petitioners have readily joined the respondent’s position that the primary responsibility is that of the school authorities and they do not suggest that this Court direct what specific plan should be adopted; their prayer for relief, as voiced during oral argument, is that the matter be remanded to the Commissioner for further consideration and action on his part pursuant to the judicial views expressed in this Court. They are clearly entitled to that relief. The Commissioner will, of course, be at liberty to have the record supplemented by such further evidence and plans as he may call for or as the parties may choose to present. Thereafter he will make whatever determination and take whatever action appears appropriate under the circumstances and the governing principles set forth earlier in this opinion.
Reversed and remanded.
