Can I apply for a scholarship on my own, without involving the scholarships director?

For most scholarships, yes, you can apply directly for a scholarship, but some major scholarships require a university nomination and often a campus committed review. See individual listings of major national and international scholarships to know which ones require you to work with Barb Stedman and perhaps another Ball State representative.

Even if official Ball State nomination is not required, you'll undoubtedly benefit from the assistance that's offered to you, free of charge, from the scholarships director and staff.
