Tyler Clementi Higher Education Anti-Harassment Act of 2015

Amends title IV (Student Assistance) of the Higher Education Act of 1965 to require each institution of higher education (IHE) participating in a title IV program (except a foreign school) to include in its annual security report a statement of policy regarding harassment that includes: (1) a prohibition of harassment of students by other students, faculty, and staff; (2) a description of its programs to prevent harassment; (3) a description of the procedures that students should follow if harassment occurs; and (4) a description of the procedures it will follow once an incident of harassment has been reported.

Defines "harassment" to include certain conduct undertaken through technological means that limits a student's ability to benefit from the IHE's programs, or creates a hostile or abusive educational environment at the school.

Authorizes the Secretary of Education to award competitive grants to IHEs to initiate, expand, or improve programs to: (1) prevent the harassment of students; (2) provide counseling or redress services to students who have been harassed or accused of subjecting other students to harassment; and (3) train students, faculty, or staff to prevent harassment or address harassment if it occurs.

Directs the Secretary to publish a report of best practices for combating harassment at IHEs.
