"The Department of Veterans Affairs (VA) administers several educational assistance programs (GI Bills®) that provide funds to or on behalf of veterans and servicemembers and their family members to facilitate their enrollment in and pursuit of approved programs of education. Participation and spending for the Post-9/11 GI Bill has represented approximately 80% or more of total GI Bill participation and spending in each year since FY2013. In FY2018, the program is estimated to benefit almost 800,000 individuals and expend over $12 billion. For a description of the other GI Bills, see CRS Report R42785, GI Bills Enacted Prior to 2008 and Related Veterans' Educational Assistance Programs: A Primer. The Post-9/11 Veterans' Educational Assistance Act of 2008 (Post-9/11 GI Bill)--enacted as Title V of the Supplemental Appropriations Act, 2008 (P.L. 110-252) on June 30, 2008--is the newest GI Bill and went into effect on August 1, 2009. There were four main drivers for the Post-9/11 GI Bill: (1) providing parity of benefits for reservists and members of the regular Armed Forces, (2) ensuring comprehensive educational benefits, (3) meeting military recruiting goals, and (4) improving military retention through transferability of benefits."
