As of FY2018, the Department of Veterans Affairs (VA) administers benefits under six GI Bills: the Post-9/11 Veterans Educational Assistance program (Post-9/11 GI Bill), Survivors' and Dependents' Educational Assistance Program (DEA), Montgomery GI Bill--Selected Reserve (MGIB-SR), Montgomery GI Bill--Active Duty (MGIB-AD), Reserve Educational Assistance Program (REAP), and Post-Vietnam Era Veterans Educational Assistance Program (VEAP). The GI Bills provide financial assistance to eligible servicemembers and veterans and their families while pursuing education and civilian job or career training. During the 114th Congress and early in the 115th Congress, Members introduced several pieces of legislation intended to update and improve the GI Bills®. Three bills were enacted in the 114th Congress to enhance GI Bill benefits, protect GI Bill participants, and collect outcome data on participants, among other purposes. Despite the legislation enacted in the 114th Congress, several issues and stakeholder requests remained outstanding. The Harry W. Colmery Veterans Educational Assistance Act of 2017 (Colmery Act; P.L. 115-48) was introduced on July 13, 2017, as a compilation of several bills, some of which had previously received committee and subcommittee hearings. This report describes the provisions of the Colmery Act, as amended. The first section describes amendments made by the law to the Post-9/11 GI Bill. The two subsequent sections describe amendments that affect multiple GI Bills and GI Bills other than the Post-9/11 GI Bill. The final sections describe amendments to other programs and a new program.
