A full benefit
Full Age and Service Retirement: at least 28 years of service credit at any age, or vested and at least age 60. Member Handbook p. 21, When am I eligible for full Age and Service Retirement?; p. 5; p. 52, Glossary, Age and Service Retirement; 24 CAR § 10-605(b)(1)
The 2026-2027 handbook (current as of July 2026) and the April 2026 planner still give 28 years at any age; 30 years appears only as the T-DROP full-participation threshold. No source shows a change from 28 to 30 years for retirement. Member Handbook pp. 5, 21, 49; 2026 Retirement Planner p. 2; T-DROP pamphlet p. 2
Retiring early
Early Age and Service Retirement: vested, 25 to 27.75 years of service credit, and not yet 60. Member Handbook p. 21, When am I eligible for Early Age and Service Retirement?; p. 53, Glossary; 24 CAR § 10-605(b)(2)
The reduction is 10% for each year less than 28 years of service credit or 10% for each year the member lacks being age 60, whichever is smaller. Member Handbook p. 21, Do I have a reduction on my retirement benefit if I retire early?; General Info pamphlet p. 2, Retirement Requirements
The actuary counts it by the month: 0.8333% for each month short (10/12 of 1%). Actuarial valuation 2025 p. C-1, item 2 (10/12 of 1% per month; Board set 10% per year from Aug. 1, 2017 by Resolution 2017-14; Board may set 5%-15% per year)
The reduction, by service and age
Percent less, for life. Ages are on your retirement date.

|---|---|---|---|
| 25 years | 30% | 20% | 10% |
| 25 years 3 months | 27.5% | 20% | 10% |

From 28 years or age 60: no reduction. Member Handbook p. 21, Do I have a reduction on my retirement benefit if I retire early?; General Info pamphlet p. 2, Retirement Requirements; Actuarial valuation 2025 p. C-1, item 2 (10/12 of 1% per month; Board set 10% per year from Aug. 1, 2017 by Resolution 2017-14; Board may set 5%-15% per year)
The handbook gives 10% per year (lesser of years short of 28 service or of age 60); the valuation gives 10/12 of 1% per month. Our calculator counts whole months from the retirement date to the 60th birthday (rounded up) and months short of 28 years from service in quarter-years. ATRS may round age months differently.
What would settle it: A.C.A. § 24-7-702 (blocked, see DOWNLOADS.md) or an ATRS early retirement estimate.Dates that matter
- The effective retirement date is the first of a month. 24 CAR § 10-601(6)
- A member who earns a full year (160+ days) of service in a fiscal year can't retire before July 1 of the next fiscal year unless at normal retirement age and not separating, or not a licensed classroom teacher vacating a classroom. 24 CAR § 10-604(d); Member Handbook p. 21, Can my effective retirement date be before July 1 if I am a classroom teacher?
- Active members file no earlier than 4 months and no later than 1 month before the effective retirement date (July 1 retirement: March 1 - May 31). 24 CAR § 10-605(c)(2); Member Handbook p. 21; p. 46, Appendix D; 2026 Retirement Planner p. 2
- A vested inactive member who left before 60 can retire from the first of the month after turning 60 (or the month after ATRS receives the application, if later). Member Handbook p. 22, When are deferred members eligible for retirement?; p. 21; General Info pamphlet p. 2
- A retirement can be cancelled within 2 full calendar months of the effective date by repaying benefits received. Member Handbook p. 22, Can I cancel my application for Age and Service Retirement?
Deferred members get benefits 'the first month after turning age 60'. Our calculator treats age 60 as met on a 1st-of-month retirement date on or after the 60th birthday for active members, and the first of the month after the birthday for deferred members. A member born on the 1st may be treated differently by ATRS.
What would settle it: A.C.A. §§ 24-7-701, 24-7-707 or ATRS confirmation.From the sources
- You can retire with a full, unreduced benefit at any age once you have 28 years of service credit, or at age 60 once you're vested.Member Handbook p. 21; p. 5
- The 28-year rule is still 28 years in the 2026-2027 handbook. Thirty years matters only for full T-DROP participation.Member Handbook pp. 17, 21
- Purchased service and established reciprocal service count toward the 28 years. Reciprocal years aren't in the ATRS benefit amount; the other system pays for them.Member Handbook pp. 12, 26
- Retirement dates are the 1st of a month. If you worked a full year (160+ days) in the fiscal year, you generally can't retire before July 1. Active members file 1 to 4 months before the retirement date; for July 1, that's March 1 through May 31.24 CAR §§ 10-601(6), 10-604(d), 10-605(c); Member Handbook pp. 21, 46
- If you leave before 60 and stay vested, your benefit can start the first of the month after you turn 60 (or the month after ATRS gets your application, if later). ATRS doesn't pay retroactively for late applications.Member Handbook p. 22
- With 25 to 27.75 years of service and under age 60, you can retire early with a permanent reduction.Member Handbook p. 21
- The reduction is 10% for each year you are short of 28 years of service, or 10% for each year you are short of age 60, whichever is smaller. Example: 26 years at age 56 is 2 years short of 28 and 4 short of 60, so the benefit is 20% lower for life.Member Handbook p. 21; General Info pamphlet p. 2
- Check with ATRSThe actuary describes the reduction month by month: 10/12 of 1% for each month short. The ATRS Board set the 10% rate in 2017 and may set it between 5% and 15%.Actuarial valuation 2025 p. C-1, item 2
