Grants are a type of gift aid that does not need to be repaid. They are typically awarded to students with demonstrated financial need; there are also a few set aside for members of the Indiana National Guard, as well as for spouses and children of some disabled or deceased veterans and public safety officers.
The FAFSA is the application for all federal grants and some state grants. Depending on your "Expected Family Contribution" determined by your FAFSA, you may receive Federal and/or State grants.
