OPINION OF THE COURT
This appeal presents a federal constitutional and a state statutory challenge to certain regulations and practices of the New Jersey Board of Medical Examiners regarding the licensing of physicians. These regulations and practices have prevented the appellant, Dr. Philip B. Eatough, Jr.,. a Doctor of Osteopathy (D.O.) and' Board licensed physician, from holding himself out to the public as an M.D. Eatough contends that this results in a violation of the United States Constitution and of the New Jersey statutes governing medical practice. The district court rejected these claims. We affirm.
I
Osteopathy, as a distinct approach to medical treatment, arose in the latter part of the nineteenth century in the mid-western United States.1 The osteopathic ap
There are presently fourteen osteopathic medical schools in the United States, all accredited by the American Osteopathic Association. The parties have stipulated that accredited osteopathic schools provide medical education equal in substance and quality to that provided by non-osteopathic schools. The subjects taught, and the content of those subjects, are the same in both types of schools (with equal numbers of classroom hours in the basic sciences and clinical work), except that osteopathic medical students are required to take, in addition, courses in osteopathic theory and manipulation (which courses may be electives in non-osteopathic schools). In New Jersey, for example, students of the Rutgers Medical School and those of the New Jersey School of Osteopathic Medicine (both are part of the University of Medicine and Dentistry of New Jersey) attend the same classes and labs in basic sciences for the first two years, while students in the latter are also required to take courses in osteopathic manipulation.
Manipulative medicine is practiced and is the subject of textbooks by both M.D.’s and D.O.’s. D.O.’s are on the faculties of many American medical schools that grant the M.D. degree, and D.O.’s are accepted with the approval of the American Medical Association (A.M.A.) into internships and residencies in A.M.A. approved hospitals. D.O.’s presently may join, and are members of, county and state medical societies as well as the A.M.A.
Licensing of persons to practice medicine in New Jersey is governed by the New Jersey Medical Practices Act, N.J.Stat.Ann. §§ 45:9-1 to 9-27.9. (West 1978). Statutory licensing requirements, Sections 9-6 to 9-14, are the same for all current applicants (regardless of medical school attended) and do not distinguish between graduates of allopathic and osteopathic schools for licensing purposes. New Jersey legislative policy has been to recognize graduates of osteopathic medical schools as fully competent in every respect to practice medicine and surgery.2
Under Section 9.2, the State Board of Medical Examiners “shall make and adopt all necessary rules, regulations and bylaws not inconsistent with the laws of the State or of the United States, whereby to perform the duties and to transact the business required under the provisions of this article (section 45:9-1 et seq.).” Eatough objects to a practice of the Board and to two related rules promulgated by it. The Board’s practice has been to issue the same license to all physicians (regardless of what medical school they attended), but to add the suffix D.O. to the names of all graduates of osteopathic medical schools, while employing M.D. for the graduates of other medical schools. There is no express statute or rule that authorizes the inscription of these suffixes on the license of any physician in New Jersey. A “Degree designation” rule passed in 1971 reads:
A physician licensed to practice medicine and surgery in the State of New Jersey shall identify himself only by that degree designation (M.D. or D.O.) which imprinted [sic] on the license issued to said person by the board; for example,Page 674John Doe, M.D., Joe Doe, O.D. [sic], Dr. John Doe, M.D. or Dr. John Doe, D.O.
N.J.A.C. 13:35-4.1. And a rule governing “Provision of information to the public” passed in 1978 provides, in pertinent part:
A licensee in the State of New Jersey may provide information to the public, by publication in a dignified manner in newspapers or comparable written publications concerning: education, certification or appointment, location and availability of services, fees for routine professional services and other pertinent information about the licensee’s practice. On any such publication, license degree must be designated....
N.J.A.C. 13:35-6.13(b).
In addition to his challenge of this practice and related rules, Eatough objects to the way the Board has chosen to treat graduates of foreign medical schools (FMG’s). FMG’s may receive a license in much the same way as graduates of schools in this country: e.g., by passing the Federation Licensing Examination (FLEX) (N.J.A.C. 13:35-3.1), or by endorsement after being first licensed to practice in another state (N.J.A.C. 13:35-3.2 and 3.3). See N.J.Stat. Ann. § 45:9-8.3 Although the Board may have no specific information concerning the medical education at these foreign schools, when it issues medical licenses to FMG’s, the Board imprints the M.D. suffix.
Eatough graduated from the Philadelphia College of Osteopathic Medicine with the degree of Doctor of Osteopathy in 1971. He thereafter completed a one year internship and two year residency in internal medicine at St. Michael’s Medical Center in Newark, New Jersey. In April of 1972, he was licensed to practice medicine and surgery in the State of Missouri, and in 1973, he was licensed by endorsement of his Missouri license to practice in New Jersey. He has also become a Diplómate in Internal Medicine, certified by the American Board of Internal Medicine in 1976, and a Diplomate in Cardiovascular Diseases, having passed all required exams of the American Board of Cardiovascular Diseases by 1979. He is affiliated with two A.M.A. hospitals in New Jersey: Riverview in Red Bank and St. Michael’s Medical Center in Newark. His practice is limited to the two specialties for which he has been trained: internal medicine and cardiovascular diseases.
Eatough asserts that he never has and does not presently employ any osteopathic manipulative techniques or principles in his practice. When he first began to practice, he used the degree designation D.O., but after coming to believe that the public did not perceive him to be a qualified physician, he substituted the M.D. suffix in his practice (e.g., in the telephone directory and on office signs). When he made a written request through his attorney that a new medical license be issued to him with the M.D. suffix thereon, however, the Board refused.
In March of 1979, two of Eatough’s patients wrote the Board to inquire whether appellant was an M.D. or an Osteopath and informed the Board that appellant was using the M.D. suffix. Although the Board responded that, as a Doctor of Osteopathy, appellant held the same license as an M.D. with all the rights and privileges to practice medicine and surgery in New Jersey, these two patients stopped seeking his services.
Following this correspondence, the Board wrote to inform Eatough that he was violating their Degree Designation rule and that he was subject to discipline unless he ceased using the M.D. suffix. Fearful of loss of his license and a fine, he sent the Board a letter of compliance, but continued to use the designation M.D. When the Board learned of this, it wrote him another letter, giving him thirty days to correct all materials used in his practice identifying him as an M.D. Eatough still refused to comply, and filed this suit in the district court on May 14, 1979.
medical degree, to do a fifth year in an A.M.A. approved hospital here. After this fifth year of additional clinical training, these students may enter an approved internship and then take the FLEX exam.
II
Eatough raises two state law claims. First he argues that the rules cited earlier concerning degree designation and providing information to the public contravene the Medical Practices Act which provides:
Any person shall be regarded as practicing medicine and surgery, within the meaning of this chapter, who shall use the words or letters “Dr.”, “doctor”, “professor”, “M.D.”, or “M.B.” in connection with his name, or any'other title intending to imply or designate him as a practitioner of medicine or surgery in any of its branches, and who, in connection with such title or titles, or without the use of such titles, or any of them, holds himself out as being able to diagnose, treat, operate or prescribe for any human disease, pain, injury, deformity or physical condition, or who shall either offer or undertake by any means or methods to diagnose, treat, operate or prescribe for any human disease, pain, injury, deformity or physical condition. The provisions of this chapter shall apply to all persons professing and attempting to cure disease by means of the so-called system of “faithcurism”, ‘“mind-healing”, “laying-on-of-hands”, and other similar systems.
N.J.Stat.Ann. § 45:9-18 (West 1978). The fact that this section makes reference to people practicing medicine without the use of titles in no way implies that such behavior must be allowed. As the last sentence of the section makes clear, the purpose of the section is to subject all persons acting like physicians to the requirements of the Act, including the licensure requirements. Thus the promulgation by the Board of the rules at issue does not conflict with this section.
Eatough also argues that the challenged rules contravene the Act by authorizing forms of advertising not allowed by N.J. Stat.Ann. § 45:9-16(j). The Board counters by pointing to a 1978 amendment to the Act specifically permitting:
A directory of physicians for consumer use which shall include the educational background, degrees, fellowships, certifications, specialties, experience and any other pertinent information which is related to the practice of medicine and surgery of the physicians.
N.J.Stat.Ann. § 45:9-16(j)(g) (West Supp. 1981-82).
We fail to understand Eatough’s challenge in this respect to the “Degree designation” rule, N.J.A.C. 13:35-4.1. Specifying that a licensed physician “shall identify himself only by” a certain degree designation does not itself authorize any form of advertising.
While we do understand Eatough’s argument with respect to the rule concerning advertising, N.J.A.C. 13:35-6.13(b), we need not decide whether, for example, the newspaper advertising permitted by that rule can be interpreted to fall within the language of the 1978 amendment to the Act. Eatough’s argument amounts to a contention that because the rule contravenes the statute in some respect, it must be considered a nullity with no application to anyone, including himself. Implicit in this argument is the contention that the rule cannot be limited or severed in such a way so as to make its application to him valid. Eatough, however, has offered no reason why we should declare a state regulation void when its application to him — i.e., preventing any advertising by him without a D.O. designation — is otherwise valid. Without any indication that New Jersey case law prohibits severability, there is no reason why we should enjoin the rule’s otherwise valid application to him.
Ill
Our rejection of his State law claims requires that we address Eatough’s constitu
It is long settled that states have a legitimate interest in regulating the practice of medicine. See, e.g., Bigelow v. Virginia, 421 U.S. 809, 827, 95 S.Ct. 2222, 2235, 44 L.Ed.2d 600 (1975); Lambert v. Yellowley, 272 U.S. 581, 597, 47 S.Ct. 210, 214, 71 L.Ed. 422 (1926); Dent v. West Virginia, 129 U.S. 114, 122-23, 9 S.Ct. 231, 233-34, 32 L.Ed. 623 (1889). In this case, both the Board and the district court, No. 79-1421, Slip Op. at 9 (D.N.J. March 25, 1981), have articulated what is certainly a legitimate state interest purportedly served by the Board’s practice and rules: allowing the public to make an informed choice among physicians.
The application of the equal protection clause in the context of such a legitimate interest has been discussed often,, and recently, by the Supreme Court. Since no one contends that the Board’s rules are burdening either a “suspect class” such as a racial or ethnic group or a “fundamental interest” such as voting — this being an example, rather, of ordinary social and economic regulation — the constitutional standard for assessing equal protection is concededly the “rational relation test.” The Court’s reluctance to overturn such legislative activity is exemplified in such recent articulations of this standard as “we will not overturn such a statute unless the varying treatment of different groups or persons is so unrelated to the achievement of any combination of legitimate purposes that we can only conclude that the legislature’s actions were irrational,” Vance v. Bradley, 440 U.S. 93, 97, 99 S.Ct. 939, 943, 59 L.Ed.2d 171 (1979); and “the Equal Protection Clause is satisfied by our conclusion that the ... Legislature could rationally have decided that [the legislative means at issue] might foster [the concededly legitimate state purpose]” (emphasis in original), Minnesota v. Clover Leaf Creamery Co., 449 U.S. 457, 466, 101 S.Ct. 715, 725, 66 L.Ed.2d 659 (1981).4
Applying the rational relation test, the district court noted both that the distinction between osteopaths and allopaths was created not by the Board, but by the two schools of medicine; and that the parties were in agreement that some patients seek out D.O.’s precisely in order to obtain the manipulative treatment such physicians ordinarily offer. Slip Op. at 9. Since the Board’s practice and rules distinguishing between M.D.’s and D.O.’s afford the public at least some aid in making their informed choices among physicians, we must concur with the district court, id., that there exists a rational relationship sufficient to pass muster under the equal protection clause.
The district court held that the meager evidence offered by the appellant indicating the low esteem in which osteopaths may be held by the public was not convincing. Slip Op. at 10. Moreover the New Jersey legislative and Board policy is to afford graduates of osteopathic schools the same rights and privileges as M.D.’s. There is no reason on the record to subject the Board’s actions to d stricter scrutiny than the rational basis standard of review requires.
Eatough also complains that the Board’s practice of granting FMG’s licenses with the M.D. suffix works an arbitrary discrimination with respect to D.O.’s. For this proposition, he cites Oliver v. Morton, supra, 361 F.Supp. at 1269, in which the district court explained that .the Georgia Board’s reasons for granting FMG’s an M.D. license — that the foreign degree is substantially equivalent to the M.D. degree and that the names given most foreign degrees have little meaning to most people in Georgia — were nearly identical to the plaintiff’s arguments in favor of being permitted to refer to himself as an M.D. rather than a D.O. Since the Georgia Board’s policy was found to treat these similarly situated groups differently without a rational basis for that distinction, the court enjoined the Board from refusing to issue the plaintiff a license bearing the M.D. designation so long as they granted such licenses to foreign-trained physicians without M.D. degrees.
But States are not required to convince the courts of the correctness of their legislative judgments. Rather, “those challenging the legislative judgment must convince the court that the legislative facts on which the classification is apparently based could not reasonably be conceived to be true by the governmental decisionmaker.” Vance v. Bradley, supra, 440 U.S. at 111.
The district court declined to follow the Oliver court on this point, Slip Op. at 9-10, and so do we. The Board’s practice of issuing M.D. licenses to FMG’s, but not to graduates of osteopathic schools, is a classification distinguishing between these two groups. Once again, however, the Board has explained that its purpose is to inform the public, and we cannot conclude that the means chosen are not rationally related to that end.
It is New Jersey policy to issue licenses to practice medicine to the graduates of foreign schools once they have passed certain examinations (e.g., the FLEX exam and an exam given by the Educational Commission on Foreign Medical Graduates). The wisdom of that policy is not at issue here. Medical schools around the world grant degrees with a large variety of names (e.g., Ireland — “M.B.B.S.”; Norway — “Candidate in Medicine”; Spain — “Licentiate in Medicine & Surgery”). The Board policy of issuing M.D. licenses to all these graduates is rationally related to the purpose of allowing the public to make an informed choice among physicians, insofar as many of the foreign degree names might only serve to confuse those seeking a physician.5 And since there are no FMG’s eligible to practice in New Jersey that come from a school identified with osteopathy, rather than allopathy, the distinction between M.D.’s and D.O.’s is rational in light of the previously mentioned purpose to inform patients of those physicians with osteopathic training. See Maceluch v. Texas State Board of Medical Examiners, No. CA-3-77-1498-G (N.D. Tex. July 10, 1981).
We can sympathize with the situation of Dr. Eatough who, having decided to abstain from practicing according to principles of osteopathy, nevertheless must suffer from the misunderstanding of some numbers of

The judgment appealed from will be affirmed.
1.
The parties submitted the case to the district court on a set of stipulated facts and agreed that all depositions, interrogatories and exhib*673sts would be made part of the record.
2.
See N.J.Stat.Ann. §§ 45:9-5.1, 9-13. This contrasts with the New Jersey statutory prohibition on holders of licenses to practice osteopathy — as opposed to licenses to practice medicine and surgery — from prescribing or administering drugs and from performing surgery. N.J.Stat.Ann. § 45:9-14.3. Section 9-14.3, while not repealed, is no longer applicable to osteopaths licensed to practice medicine and surgery.

There is also a so-called “Fifth Pathway” program designed to permit a select number of United States citizens studying in foreign schools who leave after completing all of the required courses there, but without receiving a

It is not the case, as Eatough argues, that the defendants are confined to relying upon “articulated” purposes in fact underlying the statute. In U.S. R.R. Retirement Bd. v. Fritz, 449 U.S. 166, 178, 101 S.Ct. 453, 460, 66 L.Ed.2d 368 (1980), the Court stated that “this Court has never insisted that a legislative body articulate its reasons for enacting a statute.” Cases cited by appellant do not support the converse: Johnson v. Robison, 415 U.S. 361, 376, 94 S.Ct. 1160, 1170, 39 L.Ed.2d 389 (1974) (Congress had, as is usually not the case, revealed its express objectives and no other objective was claimed); McGinnis v. Royster, 410 U.S. 263, 277, 93 S.Ct. 1055, 1063, 35 L.Ed.2d 282 (1973) (district court ordered not to discard a clear and legitimate purpose when it had perceived another purpose to be primary and found an equal protection violation based upon that purpose).
Nor is it the case, as Eatough also urges, that the purported purpose must be rejected if the challenged classification is a poor means of attaining it. The case they cite, Orr v. Orr, 440 U.S. 268, 280 n.10, 99 S.Ct. 1102, 1112 n.10, 59 L.Ed.2d 306 (1979), involves a discussion of the more severe “substantially related” requirement found in gender discrimination cases.

Neither the factual accuracy of this reasoning, nor its political wisdom, is for us to question. As the Supreme Court stated recently in Clover Leaf Creamery, supra, 449 U.S. at 463, 101 S.Ct. at 723,
