I worked as a Title IX coordinator at a K-12 institution. While most of the allegations were inocuous we had to remember that in order for it to be considered a Title IX it has to be discrimination on the basis of sex.
EXCERPT: (CFR)
Subpart C—Discrimination on the Basis of Sex in Admission and Recruitment Prohibited
§ 106.21 Admission.
(a) General. No person shall, on the basis of sex, be denied admission, or be subjected to discrimination in admission, by any recipient to which this subpart applies, except as provided in §§106.16 and 106.17.
(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.
