The TRIO programs are the primary federal programs providing support services to disadvantaged students to promote achievement in post-secondary education. The TRIO programs have been designed to prepare qualified individuals from disadvantaged backgrounds for post-secondary 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 under-represented 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.
