Student Mental Health Rights Act This bill addresses mental health and substance use at institutions of higher education (IHEs). Specifically, the bill requires the Department of Education (ED) to solicit information from students and conduct a study on mental health disabilities and substance use disorders at IHEs. In addition, ED must issue guidance on IHEs' (1) compliance with federal law on mental health, (2) legal obligations to students with mental health disabilities and students with substance use disorders, and (3) policies that may have a discriminatory impact on such students.
