Age-Based Eligibility Model

The age-based eligibility model is the framework Division I adopted on June 23, 2026 to replace the old eligibility rules. An athlete receives five years of eligibility provided they enroll in college no later than the academic year after they turn 19. It takes full effect for the fall 2027 entering class.

Q. What did it replace?

The four-seasons-in-five-years framework, along with season-of-competition limits, redshirt rules and eligibility-extension waivers. All of those were eliminated together.

Q. How does the transition work?

Athletes already enrolled, and those entering in fall 2026, may use whichever framework, old or new, is more favorable to them individually. Both systems are therefore in operation until the transition completes.

Q. What if an athlete enrolls late?

The age condition is the gate. An athlete who does not enroll by the academic year after turning 19 does not get the full five-year window, which is the model’s main constraint and the part most likely to generate disputes.

Q. Why did the NCAA change it?

It cited how difficult the old rules had become to administer amid repeated eligibility litigation. The new model is intended to be simpler and harder to challenge in court.
