## Quick answer In the TRICARE system, "Education Level" primarily refers to the student status of adult children ages 21 to 23. While standard TRICARE coverage usually ends at age 21, children enrolled full-time at an accredited college can remain on their parent's TRICARE Prime or Select plan until age 23 or graduation, whichever comes first.

## In detail Education level is a critical data point in the Defense Enrollment Eligibility Reporting System (DEERS). It acts as a "bridge" for young adults transitioning from childhood to independence.

### The "Student Status" Extension For most dependents, TRICARE eligibility expires at midnight on their 21st birthday. However, if the child is a full-time student, coverage continues under the parent’s plan (Prime or Select) provided the following criteria are met: * **Full-time enrollment:** The student must be enrolled in a full-time course of study at an approved institution of higher learning. * **Financial dependency:** The sponsor must provide more than 50% of the child’s financial support. * **The Age 23 Limit:** Eligibility under this "student status" rule ends on the student's 23rd birthday or the date they graduate, whichever occurs first.

### Updating DEERS with Education Level To trigger this extension, you cannot simply tell a doctor; you must update DEERS. Documentation required typically includes: 1. **A letter from the school registrar:** This must certify that the student is enrolled full-time in an accredited college or university. 2. **Anticipated graduation date:** DEERS uses this date to set the "end-of-eligibility" marker.

### TRICARE Young Adult (TYA) If a student drops below full-time status, graduates early, or turns 23, they no longer qualify based on "Education Level." They must then transition to **TRICARE Young Adult (TYA)**. * **2026 TYA Prime Monthly Premium:** varies by plan year — check TRICARE.mil for current rates. * **2026 TYA Select Monthly Premium:** varies by plan year — check TRICARE.mil for current rates.

### Impact on Pharmacy Benefits As long as the student is eligible via their education level, they retain full access to the **Express Scripts** pharmacy benefit, including local retail pharmacy access and home delivery, under the same cost-shares as their sponsor.

## Who this applies to * **Active Duty Families:** Allows college-aged children to stay on TRICARE Prime (often with $0 copays) until age 23. * **Retirees:** Allows college-aged children to stay on TRICARE Select or Prime (with retiree cost-shares) until age 23. * **Guard/Reserve on Active Duty:** Dependents of National Guard or Reserve members on active duty orders for more than 30 days. * **Young Adults:** Children of sponsors who are over 21 but under 23 and attending school full-time.

Common scenarios

**The Full-Time Senior** Sarah is 22 and a full-time senior at Arizona State University. Because her father (the sponsor) updated DEERS with her registrar's letter, Sarah remains on TRICARE Select. In 2026, she pays no annual enrollment fee (as a Group A dependent) and only pays standard Select copays for her doctor visits until she graduates in May.

**The Part-Time Student** Mark turns 21 in August 2026. He is taking 6 credit hours (part-time) at a community college. Because he is not a *full-time* student, his "Education Level" does not qualify him for a TRICARE extension. His coverage will terminate on his 21st birthday unless he enrolls in TRICARE Young Adult and pays the monthly premium.

**The 23rd Birthday** Leo is a full-time medical student and is still in school on his 23rd birthday in 2026. Regardless of his "Education Level" or full-time status, his standard TRICARE eligibility ends on his 23rd birthday. He must switch to TRICARE Young Adult or a commercial plan.
