In order to play Division I or II sports students need to register with the NCAA through the eligibility website. You set up an account and request your transcript to be sent through the Counseling Office.
You are not considered cleared through the Clearinghouse until a coach requests your information. At that point they will review your status to confirm what division you are clearned to play. In order to make sure you are prepared you should complete the Division I and II Worksheet to make sure you have the course work that is required.
