College basketball eligibility now depends on an athlete’s NCAA division and enrollment cohort. For Division I and II, a new age-based model generally provides a continuous eligibility period of up to five years and removes athletics redshirt rules and season-of-competition limits—but it does not guarantee five years to every player. Division I athletes with eligibility remaining after 2025–26, and prospects enrolling full time in 2026–27, may be assessed under the former rules or the new model, whichever is more favorable. Academic and other eligibility requirements still apply.
Which college basketball eligibility rules apply?
There is no single answer for every player. First identify the athlete’s NCAA division and when they first enroll full time. The NCAA’s June 2026 announcement says Division I’s age-based model takes effect for prospects first enrolling full time in fall 2027 or later. Athletes with eligibility remaining after 2025–26 and prospects enrolling in 2026–27 may be evaluated under either the former rules or the new model, whichever is more favorable to that individual. Players who used their final season in 2025–26 do not receive extra eligibility under the stated transition. NCAA announcement, June 23, 2026
The NCAA Eligibility Center describes the age-based model for Divisions I and II. The sources here do not establish the rules for other college associations or provide a complete account of Division III eligibility, so do not assume that the Division I and II framework applies to them.
What to establish for an individual player
- The NCAA division and the athlete’s enrollment cohort.
- When the athlete first enrolled full time, including whether that was at a domestic or international college or a two-year institution.
- The athlete’s age and birthday timing, which affect the new model’s age-based trigger.
- Whether the athlete had eligibility remaining after the 2025–26 academic year.
- Whether the athlete meets academic and other requirements to compete.
For an individual determination, contact the school’s compliance office. The NCAA Eligibility Center handles certification for relevant new enrollees.

Former rules and the new age-based model
| Question | Former Division I framework | New Division I and II model |
|---|---|---|
| How eligibility is measured | Generally, four seasons of competition within a five-year eligibility period, as described in the NCAA’s June 2026 announcement. | A continuous eligibility period of up to five years, generally starting at the earlier of initial full-time college enrollment or the age-based trigger described by the NCAA. |
| Does competition use up a season? | Seasons of competition were counted under the former framework. | No athletics season-of-competition limit under the new model. |
| Does sitting out pause the period? | Redshirt treatment was part of the former rules. | No athletics redshirt rule pauses the continuous clock; not competing, transferring, sitting out or changing teams does not stop it. |
| Who may be assessed under it? | Some current athletes and 2026–27 entrants may use the former rules if they produce the more favorable result during the transition. | Division I prospects first enrolling full time in fall 2027 or later; the NCAA Eligibility Center’s explainer also covers Division II. |

How the five-year eligibility period works
Under the new model, the period generally begins at the earlier of the athlete’s first full-time college enrollment or an age-based trigger: the beginning of the academic year following the athlete’s 19th birthday. The precise age trigger depends on whether the birthday falls before September 1. Because the earlier event starts the period, delaying college enrollment can mean that part of the eligibility period has already elapsed when the athlete arrives. “Up to five years” describes the maximum period, not a promise that every athlete will have five years available.

The period runs continuously. A player does not extend or pause it simply by not playing, transferring, sitting out or changing teams. The NCAA’s Division I and II age-based eligibility explainer gives the rule details; a school’s compliance staff can apply them to the athlete’s actual enrollment and birthday history.
What redshirting and sitting out mean now
Under the former Division I framework, an athlete generally had four seasons of competition within five years. Under the new Division I and II model, athletics redshirt rules and season counting are removed. A player who spends a year out of competition does not thereby stop the continuous eligibility period.

During the transition, a current athlete may still be evaluated under former rules if they lead to a more favorable individual result. That is a cohort-specific comparison by the school, not a general entitlement to a redshirt year or an added year of eligibility. The school must determine which framework applies based on the athlete’s circumstances.
Exceptions and waiver deadlines
Limited exceptions under the new model
The NCAA identifies limited exceptions, including pregnancy for the actual period the athlete cannot compete, supported by medical documentation. It also identifies active-duty military service, official religious missions and similar service commitments when the athlete does not compete in organized competition during the relevant service. These exceptions have conditions; none should be treated as an automatic extension. See the NCAA eligibility explainer for the model’s terms.

Former-rule waivers for circumstances through 2025–26
For season-of-competition or eligibility-clock extension waivers under the former rules based on circumstances occurring during or before 2025–26, the NCAA required schools to submit requests with supporting documentation by July 31, 2026. The NCAA’s June 2026 announcement states that former-rule waivers are no longer available after that deadline. An athlete with a potential individual claim should contact the school’s compliance staff; the NCAA’s Student-Athlete Reinstatement page maintains waiver guidance and resources.

Having time left in an eligibility period does not by itself make a player competition-eligible. Academic and other athletics requirements remain in force under the new model. For example, Division I initial eligibility guidance includes core-course and progression rules; it is a separate question from how much eligibility time remains. Consult the school and, where relevant, the NCAA Eligibility Center. See the NCAA’s Division I initial eligibility requirements.

How to get an athlete’s eligibility question answered
- Identify the division and cohort. Establish whether the player is in Division I or II and whether they first enroll full time before fall 2027, in 2026–27, or in fall 2027 or later.
- Build the timeline. Gather first full-time enrollment dates at any domestic or international college or two-year institution, the athlete’s birthday, and competition history.
- Check the transition rule. For athletes with eligibility remaining after 2025–26 and 2026–27 entrants, ask the school to compare the former rules with the new model and apply the more favorable outcome where the transition permits it.
- Document any claimed exception or waiver basis. Provide the records relevant to the circumstance, such as medical documentation for a pregnancy-related exception or evidence of qualifying service.
- Confirm academic and other certification separately. Ask the school’s compliance office what remains necessary to be cleared to compete; involve the NCAA Eligibility Center where applicable.
