That's a good question. I don't know where ERAU stands as a "PUBLIC institution of higher learning" but the statement below is cut from the site. If I had to guess I think UND and ERAU programs will be covered.

Post 9/11 GI Bill Yellow Ribbon Program - (U.S. Department of Veterans Affairs)
The Post-9/11 GI Bill will pay up to the most expensive in-state tuition and fees at a public institution of higher learning in the veteran's state, but you can still attend any approved school. In instances where the benefit level does not cover the cost of established charges, VA and the educational institution may enter into an agreement to cover the unmet expenses under the "Yellow Ribbon Program."
