Your question was “Why can’t I receive the same benefits for the school I have chosen to attend?” I agree with you, but the reason is because of rules – the Post 9/11 GI Bill has different rules than the Montgomery GI Bill. If you think about it, it makes sense. After all, there wouldn’t be much sense in having both GI Bills, if each covered the same thing.
The Post 9/11 GI Bill is geared toward degree-producing schools – those schools where you earn anywhere from an associate’s degree all the way to a doctorate. On the other hand, the Montgomery GI Bill (MGIB) also pays for degree-producing, but in addition, it also covers:
There is a caveat to the Post 9/11 GI Bill in that some non-degree courses are covered by the Post 9/11 GI Bill if they are taught by a school that also teaches degree-producing courses, so that is something you probably should check out.
I looked for your school in the VA-approved schools list, but I did not see it, unless it is listed under something else. I would ensure it is, in fact, a VA-approved school first before enrolling.
