The NCAA does adjust APR, on a student-by-student basis, in two circumstances. One exception that can be made, is for student-athletes who leave prior to graduation, while in good academic standing, to pursue a professional career. Another is for student-athletes who transfer to another school while meeting minimum academic requirements and student-athletes who return to graduate at a later date.Also, and I have no idea how this works, Football and basketball are headcount scholarship sports (there are 6 on the women's side). All other sports are considered equivalency scholarship sports, where it is rare for an athlete to get a full ride. My logical guess is if a student-athlete leaves early, the program's APR is only affected as a ratio of that student's scholarship aid.
