Washington DRS Retirement: PERS, TRS and SERS Plans Explained

Three Systems, Three Plan Tiers

Washington's Department of Retirement Systems administers retirement benefits for roughly 500,000 active members across three systems. PERS covers state and local government employees. TRS covers certificated K-12 educators and administrators. SERS covers classified school support staff — paraeducators, bus drivers, custodians, food service workers.

Each system offers up to three plan tiers:

• Plan 1 — closed to new members since October 1, 1977. A defined benefit pension using the highest 24 consecutive months for Average Final Compensation (AFC) and a 2% multiplier.
• Plan 2 — a defined benefit pension using the highest 60 consecutive months for AFC and a 2% multiplier.
• Plan 3 — a hybrid combining a defined benefit pension (1% multiplier, highest 60 months AFC) with a member-directed defined contribution account through Voya Financial.

The core formula for Plans 1 and 2: Service Credit Years × AFC × 2%. Plan 3's defined benefit side uses 1% instead, but members also accumulate investment returns in their contribution account.

Eligibility and Normal Retirement Age

Plans 2 and 3 members reach normal retirement at age 65. Early retirement is available starting at age 55 with at least 20 years of service credit, though actuarial reductions apply unless you qualify for the subsidized 2008 Early Retirement Factors.

That eligibility hinges on your hire date. Members who entered their plan before May 1, 2013, and accumulated 30 or more years of service, can retire at age 55 with only a 20% reduction — or at age 62 with no reduction at all. Members hired on or after May 1, 2013, cannot use the 2008 ERFs; standard factors vary by age and service, with reductions of 5% per year for members with 30 years of service and approximately 3% to 5% per year under standard tables for members with at least 20 years.

Plan 1 members follow older eligibility rules specific to their system and typically qualify with 30 years of service at any age, or at age 60 with 5 years of service.

What Happens When You Apply

Your effective retirement date is always the first day of the month following your complete separation from all DRS-covered employment. You must fully sever the employment relationship — resign, terminate active positions, and exhaust or cash out qualifying leave.

The application timeline runs roughly like this:

• 12 months out — Request an official benefit estimate through DRS Online Account Access. Audit your service credit history and resolve any missing months.
• 6 months out — Attend a DRS retirement planning webinar. Enroll in Medicare Parts A and B if you are approaching 65.
• 3 months out — Submit the official DRS retirement application (online through OAA or on paper). Select your benefit option. Get spousal consent notarized if required.
• Separation month — Complete your final shift. Your employer submits final payroll data to DRS through the Employer Reporting Application.
• After separation — DRS issues your first pension payment on the last business day of the month following your effective retirement date. Submit PEBB Form A within 60 days to keep retiree health insurance eligibility.

The Social Security Connection

Most Washington PERS, TRS and SERS members have paid into Social Security throughout their careers. The Windfall Elimination Provision and Government Pension Offset, which once reduced Social Security benefits for some public employees, were repealed by the Social Security Fairness Act signed January 5, 2025. The repeal applies retroactively to benefits from January 2024 forward. If you previously avoided filing for Social Security spousal or survivor benefits because of WEP or GPO, you need to submit a new application directly to SSA — they do not automatically enroll non-applicants.

Where a Structured Checklist Helps

DRS publishes separate handbooks for each plan, spread across dozens of pages of statutory language. The application, the benefit option election, the PEBB health insurance deadline, and the Plan 3 distribution decision each involve different agencies with different timelines. A single chronological checklist that sequences every step — from requesting your estimate through receiving your first payment — keeps the process from slipping through administrative gaps.
