Question: what is the difference between division 1-a and 1-aa?
Answer: Division 1 - FBS (1-A) & FBS (1-AA). ... The biggest difference between all levels below I-A (FBS) is scholarships and how many the school can offer. The schools playing today in the I-AA (FCS) playoffs are much smaller schools than the likes of the Ohio State, smaller student bodies and far smaller budgets.
