NCAA and NAIA eligibility calculator: the new 2026 rules
Under the NCAA's new age-based model, when you start matters as much as how fast you are. Check how many years of NCAA eligibility and how many NAIA seasons you would have at a US university, and whether a gap year would cost you one.
The short answer
NCAA Division I and II athletes now get five years of eligibility in a five-year window. The window starts at the earlier of full-time college enrolment or the start of the academic year after your 19th birthday. Start in the US by then and you keep all five years; every academic year after that uses one. The NAIA has no age limit: you get four seasons within your first 10 full-time semesters of college.
Check your NCAA and NAIA eligibility
Enter your date of birth and when you would like to start at a US university. You will see your NCAA and NAIA results side by side.
School, sixth-form college and part-time study do not count as college enrolment.
How the new NCAA eligibility rule works
- Five years, five seasons. You can compete in up to five seasons within a five-year window. There are no redshirt years to save and hardship waivers largely no longer apply.
- The window starts at the earlier of two dates: your first full-time enrolment at any college or university (at home or abroad, including junior colleges), or the start of the regular academic year after your 19th birthday.
- It keeps running. Years you spend out of college after the window starts still count.
- Three exceptions: pregnancy, active-duty military service and official religious missions can pause the clock, but only if you do not compete during that time.
How NAIA eligibility works
- Four seasons of competition. Taking part in any competition in a season uses that season.
- Within your first 10 semesters (or 15 quarters) of full-time college attendance, at any college or university.
- No age limit. Time out of education does not use NAIA eligibility, which makes the NAIA a strong route for athletes who take a gap year or start later.
- Under review. The NAIA is discussing a five-season model, possibly with age limits. Nothing has been adopted yet; we will update this calculator if the rule changes.
NCAA vs NAIA at a glance
| NCAA Division I and II (new rule) | NAIA (current rule) | |
|---|---|---|
| Seasons | 5 | 4 |
| Time limit | 5-year window | First 10 full-time semesters |
| Age-based | Yes: starts the academic year after your 19th birthday at the latest | No age limit |
| Gap year | Uses a year once your window has started | Does not use a semester |
| Full-time university study at home | Starts the window | Counts towards the 10 semesters |
NCAA examples
| Born | US start, no previous college | Estimated NCAA eligibility |
|---|---|---|
| October 2008 | August 2027 | 5 years (window 2027-28 to 2031-32; age clock would start fall 2028) |
| March 2008 | August 2027 | 5 years (window 2027-28 to 2031-32) |
| March 2008 | August 2028, after a gap year | 4 years (window already started in fall 2027) |
| March 2008 | January 2028 | 5 academic years, but the first is a spring semester only |
Examples assume the US academic year starts in August and no exceptions apply.
What this means for UK, Irish, Australian and New Zealand athletes
Many athletes in our markets finish school at 18 and start in the US the following August, which keeps all five years. The risk is a gap year, or starting a university course at home first: once you are past the academic year after your 19th birthday, or once you have enrolled full time anywhere, the clock is running. Australians and New Zealanders finishing school in November or December can still start in the US the following August, or in January for a spring start.
If your NCAA window is short, the NAIA, with no age limit, and junior colleges can still be strong routes. We help athletes find the right option every year.

Frequently asked questions
What is the NCAA five-year eligibility rule?
NCAA Division I and Division II have moved to an age-based model. Athletes get up to five years of eligibility within a five-year window. The window starts at the earlier of full-time enrolment at any college or university, or the start of the academic year after your 19th birthday. Redshirt rules and most waivers no longer apply.
When does the new rule start?
In NCAA Division II it applies from the 2026-27 academic year. In Division I it applies to athletes who first enrol full time in college in fall 2027 or later. Athletes who enrolled earlier, and Division I athletes enrolling in fall 2026, can use whichever of the old or new rules gives them more eligibility.
Does a gap year cost me eligibility?
It can. If you have already had your 19th birthday, your five-year window starts at the beginning of the next academic year whether or not you are at a US university. A gap year after that point uses one of your five years.
Does starting a university course at home start the clock?
Yes. Full-time enrolment at any college or university, at home or abroad, including junior colleges, starts the five-year window. School, sixth-form college and part-time study are not college enrolment.
Are there any exceptions?
Only three: pregnancy, active-duty military service and official religious missions. They only pause the clock if you do not take part in organised competition during that time.
How does NAIA eligibility work?
NAIA athletes can compete in four seasons within their first 10 semesters (or the equivalent in quarters) of full-time college attendance. There is no age limit, so a gap year does not use NAIA eligibility, but full-time study at a university at home does count towards the 10 semesters.
Is the NAIA changing to five years?
The NAIA is discussing a move to five seasons of competition, possibly with age limits, but nothing has been adopted. Our calculator uses the current four-season rule and we will update it if the rule changes.
Does the NCAA rule apply to junior colleges?
Enrolling full time at a junior college starts your NCAA five-year window, but the junior college associations (NJCAA and CCCAA) have their own rules for competing at that level.
How accurate is this eligibility checker?
It is an estimate based on the new NCAA rules adopted in 2026 and the current NAIA rules. It assumes the academic year starts in August and does not apply the exceptions. The rules are new and details can change, so always confirm with the NCAA or NAIA Eligibility Center or the university compliance office before making decisions.
