The "Guard and Reserve GI Bill Parity Act of 2025" seeks to expand eligibility for Post-9/11 Educational Assistance by amending title 38 of the United States Code. This legislation specifically includes various forms of full-time duty performed by members of the National Guard and other reserve components, recognizing their service for educational benefits. Key changes encompass full-time National Guard duty and active duty as defined under Title 32, alongside specific active duty calls under Title 10 for reserve components. These amendments will apply retroactively to service performed on or after September 11, 2001 , ensuring that past service qualifies, and will take effect one year after the bill's enactment.
