Absolutely. You can list up to 10 schools on the FAFSA form, and you can add them before you apply. For federal student aid, the order you list the schools doesn’t matter, but some states require a specific order for the list of schools if you want to be considered for state financial aid.
Any college you list on your application will have access to your information. Even if you’re only considering applying to the school, add it to the list. iIf and when you apply to the college, the school financial aid office will already have the FAFSA information it needs to create a financial aid package for you.
