How are the new GI Bill benefits determined?
Post-9/11 GI Bill benefit payments are structured on a tiered system and determined by the amount of creditable active-duty service you have since Sept. 10, 2001. Because Guard or Selected Reserve members and veterans enjoy the bulk of the benefits, active duty members are encouraged to use their Tuition Assistance benefits while on active duty and wait until the conclusion of their service before applying for the Post-9/11 GI Bill.
