Washington TRS and SERS Retirement: Guide for Teachers and School Employees

Washington teachers and classified school employees retire under the same DRS framework as state agency workers, but the school calendar creates timing complications that PERS members never face. Your separation date, your health coverage transition, and even your first COLA depend on when in the academic year you stop working.

TRS and SERS: Same Formulas, Different Jobs

TRS covers certificated instructional staff—classroom teachers, counselors, librarians, and administrators. SERS covers classified support staff—paraeducators, bus drivers, custodians, food service workers, and office staff.

Both systems offer Plan 2 (a pure defined benefit at 2% per year of service) and Plan 3 (a hybrid with 1% defined benefit plus a defined contribution account through Voya). The benefit formulas, early retirement factors, and benefit options (1 through 4) are identical to PERS.

What differs is the employment pattern. School employees typically work 9- to 10-month contracts, which affects service credit accrual, salary schedules, and the timing of separation.

Service Credit for School Employees

Teachers who complete a full school year earn service credit through July and August, even though they are not actively working during the summer. DRS counts the full contract year as 12 service credit months for employees who fulfill their contract obligations.

Classified staff who work hourly schedules accrue service credit differently. A service credit month is earned when you work at least 90 compensated hours in a calendar month. Part-time classified employees who work fewer than 90 hours some months will accumulate service credit more slowly than certificated teachers on full contracts.

This difference matters when you are counting years toward the 20- or 30-year thresholds for early retirement eligibility and the 2008 ERFs.

When to Retire: July 1 vs. September 1

The most consequential timing decision for school employees is whether to set a July 1 or September 1 effective retirement date.

July 1 retirement:

• Your last working day is the end of the school year (typically mid-June)
• Employer-paid SEBB health coverage ends June 30
• Your PEBB 60-day enrollment deadline runs from July 1
• Your first annual COLA takes effect the following July 1 (12 months after retirement)

September 1 retirement:

• You complete the school year and earn service credit through August
• Employer-paid SEBB coverage continues through August 31
• Your PEBB 60-day enrollment deadline runs from September 1
• Your first annual COLA does not arrive until the July 1 that follows a full year of retirement—nearly 22 months after your retirement date

The COLA timing is the hidden trade-off. Plans 2 and 3 COLAs take effect every July 1 after a full year of retirement. A July 1 retiree gets their first COLA after 12 months. A September 1 retiree waits until the second July 1 after retiring—almost two years before seeing any inflation adjustment.

On the other hand, September 1 retirement gives you two more months of employer-paid health coverage and two more months of service credit, which marginally increases your pension.

SEBB to PEBB: The Health Coverage Transition

Active school employees receive health benefits through SEBB (School Employees Benefits Board). When you retire, you transition to PEBB (Public Employees Benefits Board) retiree coverage administered by the Health Care Authority.

These are different programs with different plan options, different provider networks, and different premium structures. You cannot simply continue your SEBB plan into retirement.

The transition deadline is inflexible: submit PEBB Form A (or complete enrollment through Benefits 24/7) within 60 days after your SEBB coverage or applicable SEBB COBRA continuation coverage ends. Missing this window causes you to lose eligibility unless you later regain it, such as by returning to a PEBB/SEBB benefits-eligible position.

Without COBRA continuation, September 1 retirees whose SEBB coverage runs through August 31 have a 60-day PEBB deadline in late October. For July 1 retirees whose SEBB coverage ends June 30, the deadline is late August. If you elect COBRA, count the window from when that continuation coverage ends.

SERS-Specific Considerations

Classified staff in SERS face an additional calculation challenge. Because many classified positions are hourly and part-time, verifying your total service credit is more important than for salaried teachers.

Review your DRS service credit history through Online Account Access well before your target retirement date. Look for months that show less than a full service credit—these may be months where you worked fewer than 90 hours. If you find gaps, check whether they are accurate or reflect reporting errors by your employer.

SERS members also tend to have lower AFCs than TRS members (reflecting the pay differential between classified and certificated positions). This makes benefit option selection especially important—the dollar difference between Option 1 and Option 2 may represent a larger percentage of your household income.

Filing Your Application

The DRS retirement application process is the same for TRS and SERS as it is for PERS. Submit your application through Online Account Access at least 5 weeks before your target retirement date. If you are married, spousal consent rules apply to your benefit option election.
