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. By FY2010, the program had the largest numbers of participants and the highest total obligations compared to the other GI Bills.

Scholars have argued about U.S. state development - in particular its laggard social policy and weak institutional capacity - for generations. Neo-institutionalism has informed and enriched these debates, but, as yet, no scholar has reckoned with a very successful and sweeping social policy designed by the federal government: the Servicemen's Readjustment Act of 1944, more popularly known as the GI Bill. Kathleen J. Frydl addresses the GI Bill in the first study based on systematic and comprehensive use of the records of the Veterans Administration. Frydl's research situates the Bill squarely in debates about institutional development, social policy and citizenship, and political legitimacy. It demonstrates the multiple ways in which the GI Bill advanced federal power and social policy, and, at the very same time, limited its extent and its effects.
