CalSTRS Retirement Notification to District: When and How to Tell Your School

Your District and CalSTRS Are Separate Conversations

One of the most misunderstood steps in a CalSTRS retirement is the relationship between notifying your school district and filing your retirement application. These are two independent actions aimed at two different organizations, and getting the sequence wrong creates real problems.

Your service retirement application goes to CalSTRS — filed online through myCalSTRS up to 120 days before your effective retirement date. Your resignation for retirement purposes goes to your school district's HR department. CalSTRS does not notify your district that you are retiring, and your district does not file your CalSTRS application for you. You handle both.

When to Notify Your District

Most school district collective bargaining agreements require written notice of resignation by a specific date — commonly March 15 for a June 30 retirement, though this varies by district. Check your contract or ask your HR office for the exact deadline.

Giving notice too late can have consequences under your contract or district policy and can complicate staffing and your departure. Confirm the deadline and any late-notice consequences with your HR office.

The practical timeline:

• 6 months out: Inform your principal or supervisor verbally. This is not a legal requirement, but it sets expectations and avoids awkward scheduling conflicts during the transition.
• 3–4 months out: Submit your formal written resignation to the district HR department. This is the document the district keeps on file. Time it to satisfy your contract's notice requirement.
• 120 days out: File your CalSTRS service retirement application through myCalSTRS. This is entirely separate from the district resignation.

If your district's notice deadline falls before the 120-day CalSTRS filing window opens, you will notify the district first and file with CalSTRS afterward. That is normal.

What Your Resignation Letter Should Include

Keep it straightforward. A CalSTRS retirement resignation is a formal document, not a farewell speech. Include:

• Your full legal name and employee ID
• Your position title and work site
• A clear statement that you are resigning for the purpose of service retirement
• Your intended last day of paid service (the day before your CalSTRS effective retirement date)
• A request for written confirmation of your unused sick leave balance

That last point matters. Your district certifies your sick leave balance to CalSTRS through the Secure Employer Website (SEW) after you separate, and that certification converts unused days into additional service credit at no cost to you. Having a written record of your balance before you leave gives you something to compare against if the certified number looks wrong.

You do not need to specify which CalSTRS payout option you are selecting, your retirement benefit amount, or any other CalSTRS-specific information. Your district has no role in those decisions.

What the District Does After You Leave

Once your last day of paid service passes, your district has several obligations that directly affect when your first CalSTRS retirement check arrives:

Final earnings certification: Your district payroll office reports your final compensation to CalSTRS through SEW. This includes your last regular pay, any extra-duty pay, and unused sick leave days. CalSTRS cannot finalize your benefit calculation until this certification is complete.

Unused sick leave certification: The district reports your accumulated sick leave balance, and CalSTRS converts it into additional service credit using a simple formula: total unused sick leave days divided by the number of base service days in your contract year. For a teacher on a 180-day contract with 90 unused sick leave days, that adds 0.50 years of service credit to the retirement calculation.

Health benefit transition: CalSTRS does not provide health insurance. Your post-retirement health coverage depends entirely on what your district's collective bargaining agreement offers retirees. Some districts continue subsidized health coverage for retirees who meet age and service requirements; others offer COBRA continuation, with eligibility and duration depending on your circumstances. Attend your district's retiree health orientation before your last day so you know exactly what coverage continues, what ends, and what it costs.

Slow employer certification can delay a first retirement check. CalSTRS issues initial payments based on estimated calculations while waiting for final employer reports, but incomplete or delayed certification can push even the estimated payment back. If you have a good relationship with your district's payroll department, a polite reminder that you are expecting prompt SEW reporting helps.

The 180-Day Separation Period

Your effective CalSTRS retirement date must fall at least one calendar day after your last day of paid service or compensated leave. Once that effective date passes, the statutory 180-calendar-day separation-from-service period begins.

During those 180 days, CalSTRS-covered work triggers a dollar-for-dollar reduction to your gross retirement allowance by the amount earned, up to your full retirement benefit. A narrow exception for critical district staffing needs requires a formal board resolution and CalSTRS pre-approval before work begins under Education Code Section 24214.5.

After 180 days, limited post-retirement employment in CalSTRS-covered positions is possible under strict annual earnings caps. The rules for returning to work after CalSTRS retirement are worth understanding before you commit to any arrangements with your former district.

One Retirement, Two Timelines

Think of the process as two parallel tracks. The district track — resignation, final pay, sick leave certification, health benefit transition — is about closing out your employment. The CalSTRS track — application, option election, spousal consent, DBS distribution — is about opening your retirement.

The CalSTRS Retirement Guide maps both tracks side by side so you know which deadlines belong to the district, which belong to CalSTRS, and where the two intersect.
