If I attend Kings Point, I will probably run cross country. I have heard something as to registering with NCAA before I am eligible to run. Should I wait to do this when I find out that I am accepted/LOA?
For NCAA purposes, you are not a prospective student athlete.
"A prospective student-athlete is someone who is looking to participate in intercollegiate athletics at an NCAA Division I or Division II institution in the future."
Cross country is a D-III sport at USMMA. Our daughter is on the team and did not have to register with the NCAA in advance. However, it is a good idea for you to contact the coach now. If nothing else, he will answer any questions you have.
