This bill expands education benefits under the Post-9/11 GI Bill to National Guard members who perform full-time duty, bringing them on par with other reserve component members. Currently, National Guard members must serve on active duty orders to qualify for these educational assistance benefits, but this legislation would also include those performing full-time National Guard duty and active duty under state authority. The changes would apply retroactively to service performed after September 11, 2001, meaning eligible National Guard members could potentially claim benefits for past service. The bill takes effect one year after enactment, giving the Department of Veterans Affairs time to implement the changes. This legislation aims to eliminate disparities in educational benefits eligibility between National Guard members and their counterparts in the Reserve components of the Armed Forces.
