The opinion of the court was delivered by
Conford, P. J. A. D.(temporarily assigned). The dispositive issue before the Court is the constitutionality vel non of N. J. S. A. 18A:33-5 which exempts from the mandatory school lunch program in the public schools, N. J. S. A. 18A:33-4, those individual schools in which under 5% of the enrolled pupils qualify economically for free or reduced price lunches. The Superior Court, Chancery Division, held the exemption to deny equal protection of the laws to otherwise qualified school children in schools exempted from the mandatory program. At the same time the court held the invalid exemption provision to be severable from the act as a whole, thereby mandating the lunch program in every public school in the State. The Appellate Division affirmed in an unpublished opinion, essentially for the reasons orally expressed by the trial judge.
The School Lunch Act, L. 1974, c. 53, reads as follows:
Each sebool district shall make school lunch available to all children enrolled in the district within 1 year from the effective date of this act. Such lunches shall meet minimum nutritional standards established by the, Department of Education. Free and reduced price lunches shall be offered to all children qualifying under Statewide eligibility criteria. [N. J. 8. A. 18A:33-4],
Any school in which less than 5% of pupils enrolled meet the eligibility requirements for a free or reduced price lunch shall be exempt from the provisions of this act. [IV. J. 8. A. 18A:33-5].
The legislative history of these provisions is of some significance in relation to the equal protection inquiry whether the exemption in Section 18A:33-5 bears some rational relationship to the purpose and object of the legislation as a whole. Similar legislation had been proposed in *386the 1972 legislative session. Assembly Bill No. 1156 was captioned, “[a]n Act requiring that school lunch be made available to all children” (emphasis suppled), and contained no exemption for any schools. The accompanying statement noted that the bill’s purpose was to assure access to lunch to “all public school children in every school district.” The Assembly rejected the hill by a 67-2 vote, and did not again consider it as a body. 60 Leg. Index A-38 (No. 19 Jan. 15, 1974). The present act was submitted to the Assembly as Bill No. 442 in the 1974 session. With minor amendment, it passed in the Assembly by 67-5, again without an exemption provision. The bill then went to the Senate Education Committee where, by a 3-2 vote, it was disapproved. The committee then amended the bill by inserting for the first time the exemption now codified as N. J. S. A. 18A.-33-5.1 As thus amended, the bill passed in the Senate by 28-6 and the Assembly by 64^0. 61 Leg. Index A-12 (No. 18 July 22, 1974).
Responsibility for implementation of the act is vested in the Commissioner of Education, and has been delegated by him to the Bureau of Child Nutrition Programs of the Department of Education. Regulations concerning the providing of free and reduced price lunches are found in N. J. A. C. 6:79-l.l et seq. Each school conducts an annual survey to determine which of its enrolled students are eligible for such lunches under bureau-established standards. N. J. A. G. 6:79-1.4.
Once a lunch program is undertaken, local school districts are reimbursed by the State at a variable rate for each lunch served, the rate being determined by both the concentration of needy children per school and whether a lunch is served free or at reduced or full price. Eederal funds are available *387to reimburse the districts for 75% of the cost of purchase and installation of equipment such as refrigerators. There is no funding for salaries of local personnel involved in implementation of a lunch program except when State reimbursement for lunches exceeds costs; neither is there reimbursement for construction of necessary physical facilities.
The instant action was brought by a number of individuals in their capacities both as school board presidents and municipal taxpayers, together with the boards themselves. The complaint charged that the 5% exemption provision in the law (1) denied plaintiffs equal protection of the laws, being arbitrary and without rational relationship to the purpose of the school lunch legislation; (2) “contravene[d] the thorough and efficient education mandated by the Constitution * * *”; and (3) “create[d] an undue burden on the plaintiffs.” An injunction and a declaratory judgment were sought. Defendants Commissioner of Education and the State filed an answer and counterclaim seeking a declaration that the act was valid and an order compelling compliance with it by plaintiffs boards of education and other noncomplying school districts.
The Public Advocate was granted leave to intervene as a defendant. He originally took the position that the statute was valid. Later he urged that if the exemption provision was held invalid it should be deemed severable. On the appeal to the Appellate Division he argued: (a) that the exemption violated the 14th Amendment rights of the children in the exempted schools; and (b) the exemption provision of the act is severable. On the appeal to this Court the Public Advocate eschews any position in the matter, explaining that he fears that if the decision of the Appellate Division is affirmed new legislation is apt to be adopted cutting back on school lunches to needy pupils to a greater extent than the present act.
At the outset of the trial herein, the trial court granted summary judgment to defendants as against the plaintiff school boards on the ground that, as instrumentalities of *388the State, they had no standing to challenge the legislation. No appeal has been taken from that action. After trial the court rendered a decision construing the action to he one by the taxpayer plaintiffs on behalf of needy school children who would be deprived of lunches under the 5% exemption.2 The court concluded that the exemption was without rational basis in the purpose of the act because some children would be deprived of lunch regardless of their need and some schools would be forced to initiate a lunch program in a given year yet he exempted the following year because of a shift in the percentage of needy children at the school in that year. It therefore held the exemption invalid, and, holding the invalid provision severable, declared the law to require a lunch program in every school district. As noted above, the Appellate Division affirmed on the same reasoning. We granted certification on the petition of defendants. 75 N. J. 520 (1977).
At the trial plaintiffs adduced testimony from various school district officials to the effect that in some relatively small districts the operation of the 5% criterion would compel the institution of a lunch program and the corresponding need to purchase equipment therefor notwithstanding the fact that the percentage might subsequently fluctuate below and above the 5% level. In at least one district with more than one school the percentage threshold resulted in a larger number of needy children attending an exempt school than a complying school. However, because of State and federal financial assistance toward school lunch programs, local tax rates would be increased by only a few
*389cents on the dollar by implementation of such programs in any district.3
I
The first question engaging our attention is whether there is anyone in the case having standing to raise the question of denial to needy school children of equal protection of the laws. It seems cleaT that plaintiffs, as taxpayers seeking to invalidate the entire lunch program, do not represent the interests of such children, even though they attack the exemption provision as a step toward their ultimate position in the case. It is therefore doubtful that these plaintiffs have standing to raise equal protection claims of children. Normally an individual will be permitted only to seek judicial vindication of his own rights. Barrows v. Jackson, 346 U. S. 249, 73 S. Ct. 1031, 97 L. Ed. 1586 (1953); State v. Norflett, 67 N. J. 268, 276 (1975).4
However, we need not resolve the matter of standing here because we find that the activity of the Public Advocate *390in the case suffices to place before us the interests of the excluded school children. Eurthermore, we conclude that the strong public interest in the resolution of this dispute warrants our consideration of the merits. Busik v. Levine, 63 N. J. 351, 363-364 (1973), app. dism. 414 U. S. 1106, 94 S. Ct. 831, 38 L. Ed. 2d 733 (1974).
II
We thus address the merits of the equal protection attack as outlined above. Defendants defend the exemption provision on the following rationale. While the federal and State statutes look ultimately to the, provision of school lunches for all needy children, both statutes, and the federal implementing regulations, contemplate some flexibility in relation .to extent of coverage. As amended in 1970, the federal statute provided that “first priority * * * be given to providing free meals to the neediest children” 42 U. S. C. A. § 1758. In this connection the defendants also cite 7 C. F. R. § 210.4a (b) (5) (ii) directing “priority to schools in areas with a high concentration of needy children,” as well as such supportive cases as Davis v. Robinson, 346 F. Supp. 847, 857 (D. R. I. 1972); Justice v. Mount Vernon Bd. of Ed., 351 F. Supp. 1252, 1262 (S. D. N. Y. 1972); and Richmond Welfare Rts. Org. v. Snodgrass, 525 F. 2d 197, 201—205 (9 Cir. 1975). Thus, argue defendants, the purpose of the State statute may be stated as the provision generally of low cost lunches for children subject to an allowance for minimal local exemptions from mandatory coverage.5 The object of the 5% exemption is to assure that, with due regard for fiscal constraints, lunches will be made available in areas of greatest concentration of need.
*391In short, the defendants contend that the statute under review passes muster from an equal protection standpoint in that the category of schools exempted from mandatory participation in the program under N. J. 8. A. 18A :33-5 bears a rational relationship to the purpose of the act, that being conceived as the provision of low cost lunches to school children generally, with some fiscal leeway as ito schools where the concentration of needy children is least. It is notable that neither of the lower courts in this case gave consideration to the stated justification for the classification made by the statute. It is equally apparent that under the view of the lower courts in this case the State has the choice only of a mandatory lunch program for every school in the State or none at all. It has not been argued that the State could not, if it chose, decline to make lunch programs mandatory in any school.
In approaching the equal protection issue here implicated we see no reason to depart from the traditional criterion of rationality of the classification, i.e., whether there is “any conceivable state of facts which would afford reasonable support for [it].” WHYY Inc. v. Glassboro, 50 N. J. 6, 13 (1967) rev’d on other grounds 393 U. S. 117, 89 S. Ct. 286, 21 L. Ed. 2d 242 (1968); Two Guys from, Harrison, Inc. v. Furman, 32 N. J. 199, 218 (1960); N. J. Restaurant Assn. v. Holderman, 24 N. J. 295, 300 (1957). The United States Supreme Court has consistently applied this standard in recent years in appraising social-welfare legislation for equal protection validity. Idaho Department of Employment v. Smith, 434 U. S. 100, 98 S. Ct. 327, 54 L. Ed. 2d 324, 327 (1977); Jefferson v. Hackney, 406 U. S. 535, 549, 92 S. Ct. 1724, 32 L. Ed. 2d 285 (1972); Lindsey v. Narmet, 405 U. S. 56, 74, 92 S. Ct. 862, 31 L. Ed. 2d 36 (1972); Dandridge v. Williams, 397 U. S. 471, 485-486, 90 S. Ct. 1153, 25 L. Ed. 2d 491 (1970). The rational basis test was applied to an attack upon the implementation of the school lunch program in Briggs v. Kerrigan, 431 F. 2d 967, 968-969 (1 Cir. 1970) (upheld disparity based upon whether *392school had previously installed kitchen facilities), but cf. Justice v. Mount Vernon Bd. of Ed., supra (351 F. Supp. at 1261-1262).
In particular contexts, however, this Court has in the recent past applied a “means-focused” standard for determining equal protection; i. e., “whether there is an appropriate governmental interest suitably furthered by the differential treatment”; see Bor. of Collingswood v. Ringgold, 66 N. J. 350, 370 (1975) app. dism. 426 U. S. 901, 96 S. Ct. 2220, 48 L. Ed. 2d 826 (1976); Taxpayers Assn. of Weymouth Tp. v. Weymouth Tp., 71 N. J. 249, 281-287 (1976), cert. den. 430 U. S. 977, 97 S. Ct. 1672, 52 L. Ed. 2d 373 (1977). This approach requires more exacting judicial scrutiny than the conventional rational-basis test but less than that where “fundamental rights” and “suspect •categories” are involved in the legislation.
We are satisfied that whether the test applied is rational-basis or means-focused the statute before us does not deny equal protection (to school children. The' financial savings to the State from the exemption amount to about $500,000 (as of 1974). There are also savings to the exempted districts. This, as well as a degree of deference to local autonomy, constitutes an “appropriate governmental interest” reasonably to be served by a legislative limitation of some sort on the program, at least for the time being.
As to the asserted anomaly that of two schools in a single district a smaller absolute number of needy pupils in one school may activate a mandatory program while a larger number in another school might not, this is merely a consequence of the legislative selection of schools rather than other possible quantitative units for measurement of needy pupil concentration. That choice is not demonstrated to be clearly an unreasonable one for the stated purpose. In equal protection terms, it is not fatal “that the legislative objective might be more fully achieved by another, more expansive classification.” N. J. Restaurant Assn. v. Holderman, supra (24 N. J. at 300). “* * * [T]he Legislature may *393recognize degrees of harm and hit the evil where it is most felt.” Ilid.
We have no difficulty in finding the percentage criterion a reasonable one and the resulting exemption of the schools with the lowest proportionate concentration of needy pupils a means of recognizing the State’s economy motive which is rationally related to the general purposes and objects of the legislation. Compare Briggs v. Kerrigan, supra (431 F. 2d 967).
Ill
Plaintiffs made an alternative argument to the effect that the statutory exemption “inequitably burden [s] the taxpayers of the plaintiff school districts in violation of the equal protection clauses of the state and federal constitutions.” The contention is that unreasonable burdens are placed on the “small and poorer” districts. Plaintiffs explain:
* * The small districts will have to, spend much greater per capita amounts than large districts to build and maintain lunchroom facilities. In the poor districts, where there will be a high number of children eligible for free or reduced price lunches, the taxpayers will have, to provide the money for those lunches, while in the wealthier districts, where most children will pay for their lunches, the taxpayers will hardly be burdened at all. The system of financing the school lunch programs in New Jersey would be equitable, only if the expenses were allocated on an equal statewide basis, rather than having a disproportionate and inequitable burden on taxpayers of certain districts.
Plaintiffs’ only purported support for the assertions thus advanced consists of a dictum in Robinson v. Cahill, 62 N. J. 473 (1973), and an interlocutory decision of the Appellate Division in Bonnet v. State, 126 N. J. Super. 239 (1974). The reference to Robinson is to the Court’s allusion, in that ease, to “a question the parties have not projected, whether, apart from the equal protection guarantee, there is an implicit premise in the concept of local government that *394the State may not distribute Its fiscal responsibility through that vehicle if substantial inequality will result.” 62 N. J. at 500. It will suffice, for present purposes, to observe that we did not, in Robinson, assume the existence of any such principle nor reach the issue of whether local fiscal participation in educational costs violated any such principle. Indeed, we pointed to the “convulsive implications if home rule [were] vulnerable upon” any such principle as well as to “the difficulties of management of judicial solutions” consequent thereupon. Id. at 501. Nothing decided in Robinson v. Cahill is of aid to plaintiffs in the present situation.
As to plaintiffs’ reliance upon the Bonnet■ case, supra, the interlocutory decision there rendered by the- Appellate Division — an affirmance of a denial of a motion to dismiss a complaint for failure to state a claim — was followed by a judgment in favor of defendants after trial, and an affirmance thereof by the Appellate Division. Bonnet v. State*, 155 N. J. Super. 520 (App. Div. 1978), affirming the judgment reported in 141 N. J. Super. 177 (1976). In that case the complaint alleged that the present New Jersey system of distributing fiscal burdens, whereby counties are required to pay for part of certain judiciary and welfare program costs, denied plaintiff taxpayers, black residents and low-income families of equal protection of the laws and due process. The contention was rejected on the ground that, whether or not the functions in question were properly to be denominated as state rather than local in nature, the Legislature could properly delegate them to be borne in part by local governmental bodies. 155 N. J. Super, at 528. Thus Bonnet furnishes no support for the argument of the plaintiffs under consideration here since it is basically of the same tenor as that advanced and rejected by the Court in that case.
Insofar as asserted inequality of the burden of maintaining local schools is concerned, this Court ultimately upheld the facial constitutionality of the Public School Education Act of 1975 (L. 1975, c. 212). Robinson v. Cahill, 69 N. J. 449 (1976). That statute continues to rely to a substantial *395extent on local financing of schools. The holding in Robinson is therefore entirely consistent with the statutory scheme of imposition on local school districts of the unreimbursed (by specific state and federal sources) cost of maintenance of school lunch programs through local property taxation assisted by State aid. No individual taxpayer in any such district has a legitimate constitutional complaint flowing from the school lunch statute.
IV
As noted above, the complaint filed herein charged that the statutory exemption operated to “contravene the thorough and efficient education” mandated by the Constitution, presumably N. J. Const. (1947) Art. VIII, § IV, par. 1. However, although in advancing their equal protection argument, plaintiffs’ brief makes the point that the school lunch program was adopted by the Legislature pursuant to the constitutional mandate for a thorough and efficient educational system, the brief is devoid of any contention that the exemption provision of the statute sub judice is invalid as negating a thorough and efficient system of education. The implications of such a contention, were it advanced, are of such serious consequence that we are clearly unjustified in addressing it on our own motion, on the sparse record before us, and without adequate adversarial briefing of the issue. We therefore do not address the question.
We conclude the statute is wholly valid.
Judgment reversed.
The exemption was estimated to reduce State expenditures under the act by some $500,000. See Senate Edue. Comm. Statement, Assembly Bill No. 442 (May 13, 1974).
In doing- so it ignored the fact that the plaintiffs’ ultimate aim was to abrogate the statute in entirety by arguing that the invalid ■exempion provision was non-severable from the statute. Moreover the complaint charged that it was the plaintiffs (not the pupils) whose equal protection rights were violated by the statute.
According to an affidavit submitted by defendants, of 2,459 schools operating in the State (as of April 5, 1976), 432 schools are exempt under the act and do> not voluntarily provide a lunch program. The total of needy children in such schools numbers 3,903. The total number of needy children enrolled in schools required to provide a lunch program under the act is 289,164. An additional 8,487 needy children are voluntarily given lunch by schools exempt from the act. Thus the percentage of all needy children in the State not being afforded lunch is 1.35%.
Exceptions to this rule have been invoked in some situations where a party alleges that his own injury necessarily deprives third parties of their constitutional rights. See, e. g., Barrows v. Jackson, supra, 346 U. S. at 257, 73 S. Ct. 1031 (enforcing a restrictive covenant against a white covenantor would deny blacks equal protection) ; Pierce v. Society of Sisters, 268 U. S. 510, 534, 535, 45 S. Ct. 571, 69 L. Ed. 1070 (1925) (if religious schools closed, parents, students and teachers would be denied substantive due process). No such nexus exists here; the interests of plaintiffs and school children are disparate. See generally Note, “Standing to Assert Constitutional Jus Tertii,” 88 Harv. L. Rev. 423, 428-436 (1974).
It is to be noted that no contention bas been made in this case that our statute does not comport with the federal statutes or regulations.
