High schools will begin deciding which of their courses meet the NCAA core-course requirements for freshman eligibility standards under a plan approved Tuesday by the NCAA Division I board of directors.

The process now is done by the NCAA’s clearinghouse, which receives course titles sent in by the athlete and the high school and then determines whether incoming freshmen are academically eligible.

Now, the signature of the high school principal will attest that the courses submitted satisfy the core-course requirements, which the clearinghouse will still verify, the board said.

The board said the only instances in which additional support for a new course submission would be required are those in which:

A high school wants to have a course approved retroactively for a student who has already graduated.

The course title suggests offerings that typically do not meet the 75 percent instructional-content criteria.

The submission for a course that has been previously denied.

The procedural change does not reflect any change in initial eligibility standards, the board said.
