ROTC 3 year scholarship 1st year?

Paying for College

Looking for any input. Son has been awarded a 3 year ROTC scholarship covering full tuition and fees . It doesnt start till Soph.year. Has anyone had success using that when meeting with schools about cost? Possibly having out state tuition waved, room and board provided, etc. I some know schools provide this to all ROTC scholarship is winners. Sadly his top school does not. It was suggested we in a since leverage what he has with the schools directly. Is this wrong? Does it work? Would love any thoughts
