The TRIO programs are the primary federal programs providing support services to disadvantaged students to promote achievement in postsecondary education. The TRIO programs have been designed to prepare qualified individuals from disadvantaged backgrounds for postsecondary education and encourage their success throughout the educational pipeline from secondary school to undergraduate and graduate education. While the TRIO programs primarily serve low-income, first-generation college students, they also serve students with disabilities, veterans, homeless youth, foster youth, and individuals underrepresented in graduate education. This book provides a description of the TRIO programs, with a focus on education for homeless children and youth; and the federal Pell Grant program of the Higher Education Act.
