Every school does them differently. You’d have to know if the sport is fully funded (with 6.3 scholarships) at your school. Then you’d need to know if the school has a full roster (ave. 24) and if the coach splits the scholarships evenly, per class, gives more to jrs and srs and less to freshmen and sophs, gives full scholarships to some and nothing to others, gives at least book money to everyone or a small amount ($2000) to everyone.
Some coaches weigh the athletic scholarship against the merit scholarship. If the coach knows your child will get a big merit award, coach might hold back some funds for a student who won’t get enough in merit. My daughter has a bigger merit scholarship than athletic grant, and also gets some state money that other players don’t get, and the coach knows it.
As a freshman, she got about 1/2 of her tuition in athletic grant. As tuition rose, the athletic grant didn’t so now it about 1/3 tuition, even though it is the same amount in dollars. The math is really complicated. The award can be a percentage or a set dollar amount for tuition, room and board, or books. A percentage might be better as if costs rise, so does your aid.
