EFC too low??

Not likely. Though there are debates on this issue. Imo, those schools are need blind in admissions. I would call the Admissions Office of each of them and ask if they are need blind for OOSers, as it is possible (I doubt likely, but possible, that they are not)

I think the larger issue is that you are highly unlikely to get full need met at those schools. Not a one of them guarantee to meet full need, even to their own residents . And your kid comes after their own residents There might be merit possibilities for him which along with his federal entitlements that could do him well.

I suggest looking at your state schools and possibilities as well. There might be state entitlements in the picture and your son would be first in line for them as an in stAte resident.

With his stats, and low EFC, he could be eligible for merit within need grants at a number of schools. You might want to look at some of them. There are schools that seek low income high performing students. Ironically, they are often considered Need blind when they do give quarter to such students

I had heard a rumor some years ago that UA asks for PROFILE at times for FAFSA results out of line. I don’t know if they still do this. Might want to ask when you call them.

Make sure that your son has truly affordable schools on his list, once the EFC normalizes. None of these schools are safeties if there is any financial aid contingency attached to them because none of them are likely to meet need for your son.
