If there's only 9-11 campuses left, there's likely no need for a centralized location for Ai schools . DCEH could easily move things over to LA where Dream Center is headquartered.
Ai was always the outlier in the whole EDMC purchase. An arts school where most students end up as their own business as freelancers isn't the vocational training that Dream Center seemed to be aiming towards. The nursing programs, the medical technician programs... those fit much closer. EDMC just made sure that if DCEH wanted South and Argosy, they had to take Ai as well.
