If your daughter doesn’t want to answer she doesn’t have to but then it is likely the Cornell coach will drop her from recruiting. If you don’t think it is legit, ask the coach before giving any info. I often said to the coach, “I don’t understand this form or what it will be used for, can you explain why you need it or how this works?”
Recruiting isn’t a fair or level playing field. Some get special treatment, some get admitted with grades that are below what the general application pool have, some get more money than others. My daughter got a lot of merit money from her school, and because she was a state resident got some money from the state. The coach considered all that when deciding how much athletic money to award and I thought that was unfair, that daughter should get the merit money for her good gpa and scores and the athletic money because she was a better athlete than some of the other kids. The coach felt she could ‘save’ money on my daughter because the state and school were giving her more than others.
Coaches get to ask whatever they want to, on an official form or on the back of a napkin but you can ask why they need the info.
