College bound athletes who hope to compete for a Division I or II college must register with the NCAA Clearinghouse. The cost to register is $90. Division III or undecided athletes should also complete a profile. Athletes should monitor their clearinghouse account to be sure they have submitted all required documents in a timely manner, including coordinating with their high school to send transcripts at required intervals.
