Title IX of the Education Amendments of 1972
§ 106.21 Admission.
(b) Specific prohibitions.
(1) In determining whether a person satisfies any policy or criterion for admission, or in making any offer of admission, a recipient to which this subpart applies shall not:
(i) Give preference to one person over another on the basis of sex, by ranking applicants separately on such basis, or otherwise;
(ii) Apply numerical limitations upon the number or proportion of persons of either sex who may be admitted; or
(iii) Otherwise treat one individual differently from another on the basis of sex.
(2) A recipient shall not administer or operate any test or other criterion for admission which has a disproportionately adverse effect on persons on the basis of sex unless the use of such test or criterion is shown to predict validly success in the education program or activity in question and alternative tests or criteria which do not have such a disproportionately adverse effect are shown to be unavailable.
(c) Prohibitions relating to marital or parental status. In determining whether a person satisfies any policy or criterion for admission, or in making any offer of admission, a recipient to which this subpart applies:
(1) Shall not apply any rule concerning the actual or potential parental, family, or marital status of a student or applicant which treats persons differently on the basis of sex;
(2) Shall not discriminate against or exclude any person on the basis of pregnancy, childbirth, termination of pregnancy, or recovery therefrom, or establish or follow any rule or practice which so discriminates or excludes;
(3) Shall treat disabilities related to pregnancy, childbirth, termination of pregnancy, or recovery therefrom in the same manner and under the same policies as any other temporary disability or physical condition; and
(4) Shall not make pre-admission inquiry as to the marital status of an applicant for admission, including whether such applicant is “Miss” or “Mrs.” A recipient may make pre-admission inquiry as to the sex of an applicant for admision, but only if such inquiry is made equally of such applicants of both sexes and if the results of such inquiry are not used in connection with discrimination prohibited by this part.
