For decades, the rule was simple to state even if it wasn't always simple to navigate: a Division I athlete got five years to complete four seasons of competition, with the clock starting the moment they enrolled full-time. The redshirt year existed inside that structure -- a way to sit out competition for a season without burning one of your four. On June 23, 2026, the NCAA Division I Cabinet unanimously threw that whole framework out for something built around age instead of a fixed season count.
The old rule vs. the new one
Under the age-based model, a Division I athlete gets five seasons of competition within a five-year window. That window starts at whichever comes first: the athlete's initial full-time college enrollment, or the start of the academic year following their 19th birthday, if that birthday falls before September 1. Josh Whitman, the Illinois athletic director who chairs the Division I Cabinet, called it "decisive action for the benefit of student-athletes and the system of NCAA Division I athletics."
The practical shift: instead of counting how many seasons you've actually competed in, the NCAA now counts how old you were when your five-year clock started. An 18-year-old enrolling straight out of high school gets essentially the same runway as before. An athlete who spent extra years elsewhere first -- prep school, a gap year, juco -- now has that time counted against their five-year window in a way the old four-seasons rule didn't force.
What gets eliminated along with it
The Cabinet didn't just swap one number for another -- it stripped out several rules that existed specifically to manage the old system:
- Season-of-competition limits -- there's no separate "four seasons" cap to track anymore, since the model is built around the five-year window itself.
- Sport-specific eligibility rules that varied by sport under the old framework.
- The redshirt designation itself. The mechanism our piece on Academic Redshirt status describes -- sitting out competition for a season without it costing you a year of eligibility -- doesn't have the same function once eligibility isn't counted in discrete seasons-of-competition in the first place.
- Eligibility-extension waivers, the case-by-case appeals athletes used to file for an extra year.
A narrow set of exceptions survive: pregnancy, active-duty military service, and official religious missions can still pause or delay an athlete's five-year window.
Who this actually applies to first
The rule doesn't flip on for everyone at once. It's mandatory for athletes first enrolling full-time in college in fall 2027 or later -- that's the class it fully governs. Athletes enrolling in fall 2026, along with current student-athletes who still have eligibility remaining after the 2025-26 academic year, get a choice: schools apply whichever system, old or new, produces the more favorable outcome for that individual athlete. Athletes who'd already used their final season of competition by the end of 2025-26 don't get extra eligibility retroactively created by the new model.
That transition detail matters because the eligibility rules that keep an athlete competing year to year -- credit-hour minimums, percentage-of-degree benchmarks -- still run independently of which eligibility model an athlete falls under. A more generous eligibility clock doesn't relax those separate academic-progress requirements at all.
Why this isn't fully settled yet
The new rule immediately drew a legal challenge from athletes it disadvantaged: a group from the high school Class of 2022 who had already exhausted four seasons of competition under the old rule, and who argued the new model arbitrarily cut them out of a fifth season -- including the ability to keep earning NIL and revenue-sharing compensation -- in violation of antitrust law. In Wisne v. NCAA, filed in the U.S. District Court for the District of Colorado, Judge Charlotte N. Sweeney granted a class-wide preliminary injunction on July 31, 2026, ordering the NCAA to treat that entire Class of 2022 group as eligible for a fifth season. The NCAA appealed, and the U.S. Court of Appeals for the Tenth Circuit paused that injunction on August 21, 2026, pending further review -- meaning the question of whether those specific athletes actually get a fifth season was still unresolved in the courts as of this fall, not settled in either direction.
That makes this a genuinely live situation rather than a closed one: an athlete in that specific Class of 2022 group with remaining college aspirations should check the current state of the litigation directly rather than assume either the injunction or the stay is the final word, since an appeals court can rule again at any point.
What this means for you
- If you're enrolling in fall 2027 or later, plan around the age-based model -- it's not optional for your class. Know your own 19th-birthday date relative to September 1 of your enrollment year, since that's what actually starts your five-year clock, not just the day you show up on campus.
- If you're enrolling in fall 2026 or you're already competing with eligibility left, you're not locked into either system automatically. Ask your compliance office which model actually works out better for your specific situation -- it's decided case by case, not applied uniformly to your whole class.
- Don't assume "redshirt" still means what it used to. The label is being phased out along with the season-counting system it was built for -- a program using the term informally in 2027 and later may not mean the same formal NCAA status it did before.
- A generous eligibility clock doesn't touch the separate rules for staying academically eligible year to year -- the credit-hour and percentage-of-degree benchmarks run independently and still apply in full.
- If you or someone you know falls into the disputed Class of 2022 group, check the current litigation status directly rather than relying on news from earlier in 2026 -- the injunction is stayed, not resolved, as of this writing.
