When your daughter was accepted did they send the financial aid package with her acceptance or in a separate email? Did you check her spam folder?
Did your family fill out the FAFSA? You can still fill out an application, but the financial aid offices usually budget most of their funds for the students by the time of acceptance.
In my experience, the art-based schools are very expensive and have limited funds for scholarships but it doesn’t hurt to ask.
As for the national merit scholarship, there are certain schools that fully fund national merit winners. Our son chose not to attend those schools so his award was less than $3000 a year from the national merit foundation.
