The U of Colorado does not. If he gets merit money, it will be $6250/yr ($25k for 4 years) but the OOS tuition is pretty high, engineering is an extra $2000, and the cost of room and board is high too. CU has plenty of OOS applicants so doesn’t need to discount to fill the class. The school decided not to raise tuition for this coming year but are losing a lot of state money so I would not be surprised to see those scholarships shaved a little for future classes.
The private schools can give good merit aid, but are usually pretty expensive to begin with.
I know a student who received a lot of money from UVA, but then lost the merit scholarship for gpa falling below 3.0. Then she was at a very expensive school and having to decide if she wanted to transfer or pay up.
