You might check old Miami threads to see.
In general, one shouldn’t ED if they “want” or “hope for” a merit scholarship.
Merit is the way for a university to buy kids in who won’t go there. It’s their marketing or incentive budget. Why spend if it’s not necessary and it’s not on ED since those kids are bound.
Most say - and Miami does too - that ED can get merit - and it’s smart of them to toss out at least a few - so that kids don’t avoid ED - because schools love ED. Why wouldn’t you - it’s a guaranteed butt in seat.
My daughter’s year - everyone she knew (5 or 6) got $25K. None were ED but that’s a small sample.
Hopefully if you read past year threads, you’ll see examples yay or nay to help inform you.
Last year of 48,000 applied. 1,645 applied ED. What percentage were athletes I don’t know - but the ED acceptance rate was very high (60%) vs. 18.5% overall.
Men, by the way, are admitted at 22% vs. 16% for females - so there’s an advantage that you have a son. Far few men than women apply (last year 28K+ female to 19K male.
Not what you asked for but never ED if you “want” money. But look at past year threads to see if anyone provided the answer you need.
