The new job is exciting. The pension paperwork is where careers quietly lose six figures. Here is the map to read before you sign anything.
Changing districts usually changes nothing. A teacher moving from one district to another stays in CalSTRS, and her service credit keeps stacking.
Changing systems is the trap. Teacher to classified administrator means CalSTRS to CalPERS. District to county or city can mean CalPERS or a ’37 Act county plan. Each move quietly resets the rules on your largest asset.
The six-month window
California’s systems — CalPERS, CalSTRS, the county plans, UCRP — run a reciprocity network. Reciprocity — a formal link between two pensions — moves no money and no service credit. You join both systems, retire from both, and collect two checks.
What it does move is valuable. With reciprocity established and both retirements on the same date, your highest salary — usually the later job’s — can price both pensions. Ten years of 2000s teaching paid at today’s administrator salary is real money, monthly, for life.
It also preserves your status. Enter the new system within 6 months, funds still on deposit, and you generally stay a Classic member with your original formula generation.
Break the chain and PEPRA — the 2013 pension reform law — treats you as brand new: later factor peaks and a $178,820 pay cap in 2026. One relaxed seven-month sabbatical between employers can downgrade every future year of service. And reciprocity is not automatic; you request it, in writing, for each move.
The vesting cliff
Both systems generally vest at 5 years. Vesting means earning the right to a lifetime monthly check at all.
At 4 years and 11 months, you have contributions plus interest. At 5 years, you have a pension. Compounded over a 25-year retirement, that difference is routinely six figures.
Reciprocal membership can help you meet vesting across systems — one more reason to file the paperwork properly. Still, if a new offer lands near the five-year line, the start date is a negotiation point. Count your service credit before you sign.
The refund trap
When you leave, the old system cheerfully offers your contribution balance back. For a mid-career teacher, that number can look like a remodel. Taking it is almost always the wrong move.
The refund returns only your money and interest. You forfeit the service credit, the employer’s side of the funding, and the lifetime benefit those years would have paid. It can also break reciprocity and trigger taxes and early-withdrawal penalties.
Regret it later and you can redeposit — buy your own years back — but the price grows with your age and salary. The right default: leave the money on deposit and let two pensions work.
One account moves with you no matter what: the 403(b) or 457(b). It rolls from district to county to city, and it smooths whatever the formulas fracture. If a move is coming, the years before it are exactly when those contributions matter most.
Before accepting, run the checklist. Name both systems. Count your credit. Keep the gap under six months and the funds on deposit. Request reciprocity in writing and keep the confirmation letter. Then plan to retire from both systems on the same day, so the salary linkage applies.
