Higher Education Access and Success for Homeless and Foster Youth Act This bill revises provisions related to financial aid and higher education programs for children and youths who are homeless or in foster care. It requires institutions of higher education (IHEs) participating in financial aid programs to, among other things, simplify the financial aid determinations process for these students. It also requires IHEs to designate a staff liaison to assist these students with support services, programs, and community resources in a variety of areas, including financial aid and housing. The bill also requires these students to receive in-state tuition rates at public IHEs. Under current law, some states offer these students in-state tuition or provide them with tuition waivers.
