What Triggers the Continuous Five-Year Eligibility Period?
The NCAA has adopted a new age-based eligibility rule that permits Division I student-athletes up to five years of eligibility if they enroll in college no later than the academic year after their 19th birthday. Under this model, as outlined in the NCAA Division I Age-Based Eligibility Rules: Eligibility 101, a student-athlete's five-year eligibility period begins with the earlier of two events: initial full-time college enrollment or the age-based trigger.

According to the NCAA Division I Age-Based Eligibility Rules: Eligibility 101, the age-based trigger is defined as the start of the regular academic year immediately following the student-athlete's 19th birthday, if the student-athlete turns 19 years old before Sept. 1. For an individual who turns 19 years old on or after Sept. 1, the period of eligibility begins at the start of the subsequent academic year, unless the individual enrolls full time in college earlier.
According to the NCAA, the adjustment to start the eligibility clock at initial full-time enrollment or the academic year following the 19th birthday follows recommendations from stakeholders in men's ice hockey, men's basketball, and the U.S. national service academies.

How Do Redshirt and Season-of-Competition Rules Change?
According to the NCAA, the new rule streamlines a significant portion of the Division I rule book by eliminating season-of-competition limits, sport-specific eligibility and redshirt rules, and eligibility extension waivers. As explained in the NCAA Division I Age-Based Eligibility Rules: Eligibility 101, the previous eligibility rule counted seasons of competition, whereas the new age-based eligibility rule is based on a continuous five-year eligibility period, replacing previous tracking variables with one consistent eligibility period.
According to the NCAA Division I Age-Based Eligibility Rules: Eligibility 101, once the five-year period starts, it runs continuously and does not pause because a student-athlete does not compete, transfers, sits out, changes teams, or takes time away from participation. Under these NCAA guidelines, because the five-year period runs continuously, student-athletes, coaches, and athletics departments no longer have to track athletic redshirts. transfers
As detailed in the NCAA Division I Age-Based Eligibility Rules: Eligibility 101, the previous eligibility rule could vary by sport or circumstance, whereas the new age-based eligibility rule applies a consistent framework across all Division I sports. Additionally, the previous eligibility rule included multiple waiver options, whereas the new age-based eligibility rule uses limited exceptions written into the rules.
What Are the Transition Rules for Fall 2026 Entrants?
According to the NCAA, for students enrolling full time in college for the first time in fall 2026 and current student-athletes with eligibility remaining after the 2025-26 academic year, Division I schools will apply the previous rules or the age-based model, whichever results in the most favorable outcome. Prospects who initially enroll full time at any college or university during 2026-27 will use either the previous rules or the new age-based model, whichever is most beneficial.
Under NCAA rules, student-athletes who used their final season of competition under previous rules during 2025-26 will receive no additional eligibility. For current student-athletes with eligibility remaining under the previous rules, schools must submit any season-of-competition or eligibility clock extension waiver requests based on circumstances that occurred during or before the 2025-26 academic year to the national office no later than July 31, 2026.
When Does the Model Apply Fully to Fall 2027 Entrants?
According to the NCAA, the age-based eligibility model changes will be fully implemented for the fall 2027 incoming class. The rule change will be effective for all prospects initially enrolling full time in college in fall 2027 or later. Prospects who initially enroll full time at any college or university in fall 2027 or later must use the age-based model only.
As specified by the NCAA, under the age-based eligibility model, waivers will not be available, including clock extensions and waivers previously granted for hardships, seasons of competition, and delayed enrollment. As detailed in the NCAA Division I Age-Based Eligibility Rules: Eligibility 101, waiver categories being eliminated include medical hardship waivers, extension-of-eligibility waivers, season-of-competition waivers, athletics activity waivers, and delayed enrollment waivers.
What Exceptions and Academic Requirements Still Apply?
According to the NCAA, exceptions that could delay or pause an individual's period of eligibility under the age-based rules include pregnancy, active-duty military service, and official religious missions. These exceptions will only be available if the student-athlete does not participate in organized competition for the duration of the exception. The NCAA Eligibility Center will administer the use of the exceptions for consistency throughout Division I.
As outlined in the NCAA Division I Age-Based Eligibility Rules: Eligibility 101, time spent in active-duty military service, on an official religious mission, or in a similar service commitment may be excluded from the five-year period if the student-athlete does not participate in organized competition during that service. If the student-athlete competes during the service period, the exception does not apply. A pregnant student-athlete may pause the eligibility period for the duration of the actual period during which the individual cannot compete, and supporting medical documentation is required.
According to NCAA Division I Academics guidelines, progress-toward-degree requirements are designed to guide student-athletes to graduation within five years of initial enrollment. Division I student-athletes must complete 40% of required degree credit before the start of their third year of enrollment, 60% before the start of their fourth year, and 80% before the start of their fifth year. As noted in the NCAA Division I Age-Based Eligibility Rules: Eligibility 101, other eligibility rules, including academic and other athletics-related rules, will still apply, meaning a student-athlete may be inside the five-year eligibility period and still be ineligible for other reasons.
