First, an important note about the NCAA Clearinghouse:
Athletes, it is your responsibility to become familiar with the eligibility rules of both the NCAA and the colleges and universities to which you're applying. If you are applying to an NCAA Division I or Division II institution, YOU MUST REGISTER with the NCAA Clearinghouse by the end of your UPPER year, or you risk losing your chance to accept invitations to "official" on-campus recruiting visits and your freshman year of intercollegiate athletics. The necessary forms and explanatory booklets are available in the CCO. Feel free to discuss these procedures with your college counselor and coach(es).
