The U.S. Department of Veterans Affairs (VA), previously named the Veterans Administration, has been providing veterans educational assistance benefits, including GI Bill benefits, since 1944. The benefits have been intended, at various times, to compensate for compulsory service, encourage voluntary service, prevent unemployment, provide equitable benefits to all who served, and promote military retention. In general, the benefits provide grant aid to eligible individuals enrolled in approved educational and training programs. The newest GI Bill was enacted on June 30, 2008, as the Post-9/11 Veterans' Educational Assistance Act of 2008 (Post-9/11 GI Bill), Title V of the Supplemental Appropriations Act, 2008 (P.L. 110-252). This report provides a detailed description of the Post-9/11 GI Bill. The first section introduces the concept of entitlement. The second section describes participant eligibility criteria. The third section discloses the period during which the benefits must be used. The subsequent section describes the eligible programs of education. This is succeeded by an explanation of the eligible benefit payments. The final section illustrates current data on obligations and participation.
