*543Per Curiam.

Petitioner Mrs. Ida Phillips commenced an action in the United States District Court for the Middle District of Florida under Title YII of the Civil Rights Act of 1964* alleging that she had been denied employment because of her sex. The District Court granted summary ■judgment for Martin Marietta Corp. (Martin) on the basis of the following showing: (1) in 1966 Martin informed Mrs. Phillips that it was not accepting job applications from women with pre-school-age children; (2) as of the time of the motion for summary judgment, Martin employed men with pre-school-áge children; (3) At the time Mrs. Phillips applied, 70-75 % of the applicants for the position she sought were women; 75-80% of those hired for the position, assembly trainee, were women,, hence no question of bias against women as such was presented.

The Court of Appeals for the Fifth Circuit affirmed, 411 F. 2d 1, and denied a rehearing en banc, 416' F. 2d *5441257 (1969). We granted certiorari. 397 U. S.. 960 (1970).

Section 703 (a) of the Civil Rights Act of 1964 requires that persons of like qualifications be given employment opportunities irrespective of their sex. The Court of Appeals therefore erred, in reading this section as permitting one hiring policy for women and another for men— each having pre-school-age children. The existence of such conflicting family obligations, if demonstrably more relevant to job performance for a woman than for a man, could arguably be a basis for distinction under § 703 (e) of the Act. But that is a matter of evidence tending to show that the' condition in question “is a bona fide occupational qualification reasonably necessary to the normal operation of that particular business or enterprise.” The record before us, however, is not adequate for resolution of these important issues. See Kennedy v. Silas Mason Co., 334 U. S. 249, 256-257 (1948). Summary judgment was therefore improper and we remand for fuller development of the record and for further consideration.

Vacated and remanded.

Mr. Justice Mahshall,

concurring.

While I agree that this case must be remanded for a full development of the facts, I cannot agree with the Court’s indication that a “bona fide occupational qualification reasonably necessary to the normal operation of” Martin Marietta’s business could be established by a showing that some women, even the vast majority, with pre-school-age children have family responsibilities that, interfere with job performance and that men do not usually have such responsibilities. Certainly, an employer can require that all of his employees, both men and women, meet minimum performance standards, and *545he can try to insure compliance by requiring parents, both mothers and fathers, to provide for the care of their children so that job performance is not interfered with.

But the Court suggests that it would not require such uniform standards. I fear that in this case, where the issue is. not squarely before us, the Court has fallen into the trap of assuming that the Act permits ancient canards about the proper role of women to be a basis for discrimination. Congress, however, sought just the' opposite result.

. By adding1 the prohibition against job discrimination based on sex to the 1964 Civil Rights Act Congress intended to prevent employers from refusing “to hire an individual based on stereotyped characterizations of the sexes.” Equal Employment Opportunity Commission, Guidelines on Discrimination Because of Sex, 29 CFR § 1604.1 (a)(1)(h). See Bowe v. Colgate-Palmolive Co., 416 F. 2d 711 (CA7 1969); Weeks v. Southern Bell Tel. •& Tel. Co., 408 F. 2d 228 (CA5 1969). Even characterizations of the proper domestic roles of the sexes were not to serve as predicates for restricting employment opportunity.2 The exception- for a “bona fide occupational qualification” was not intended to swallow the rule.

That exception has been construed by the Equal Em-, ployment Opportunity Commission, whose regulations are entitled to “great deference,” Udall v. Tallman, 380 U. S. 1, 16 (1965), to be applicable only to job situations' *546that require specific physical characteristics necessarily possessed by only one sex.3 Thus the exception would apply where necessary “for the purpose of authenticity or *547genuineness” 4 in the employment of actors or actresses, fashion models, and the like.5 If the exception is to be limited6 as Congress intended, .the Commission has given it the only possible construction.

When performance characteristics of an individual are involved, even when parental roles are concerned, employment opportunity may be limited only by employment criteria that- are neutral as to the sex of the applicant.
