Substitute teachers in California do get benefits, but which ones depend on how many hours you work, what kind of assignment you hold, and which district employs you. Retirement contributions and paid sick leave apply broadly. Health insurance, unemployment during school breaks, and district-specific perks depend on thresholds and circumstances. Here is what actually applies to a substitute, and what has to line up before each benefit kicks in.
Retirement Contributions Start Immediately
California requires substitute teachers to participate in a public retirement system, with contributions deducted from every paycheck. This one is not optional and does not wait for a full-time threshold.
Substitutes performing credentialed teaching duties are covered by the California State Teachers’ Retirement System. For the 2025–26 fiscal year, members contribute 10.25 percent of their earnings under the CalSTRS 2% at 60 plan, or 10.205 percent under the CalSTRS 2% at 62 plan.1CalSTRS. Contributions Those rates apply whether you work one day a week or five. The money funds a Defined Benefit pension paying monthly income in retirement, calculated from your service credit and final compensation.
Substitutes working less than half-time may instead be enrolled in the CalSTRS Cash Balance Benefit Program. It functions more like a 401(k): your contributions and the employer’s contributions earn a guaranteed interest rate, and you receive the balance when you leave the system or retire. If your assignment later grows to 50 percent or more of a full-time position, you move automatically into the Defined Benefit program.2CalSTRS. Cash Balance Benefit Program FAQ Not every district offers Cash Balance, so ask.
If You Already Have CalPERS Time
If you previously held a classified (non-teaching) position covered by the California Public Employees’ Retirement System and then moved into a credentialed substitute role, you may be able to elect to stay with CalPERS instead of switching to CalSTRS. The election must be made within 60 days of your hire date in the new position, and you generally need to be an existing CalPERS member with at least five years of service credit.3CalPERS. Circular Letter 200-054-22 Changes to the Retirement System Election Eligibility Criteria Ask your district’s HR office for the Retirement System Election form (ES 372) as soon as you start. The 60-day window closes fast.
Paid Sick Leave
California’s paid sick leave law covers substitute teachers. You accrue one hour of paid sick leave for every 30 hours worked, with a right to use at least 40 hours (five days) per year.4California Department of Industrial Relations. Healthy Workplace Healthy Family Act of 2014 (AB 1522) That 40-hour floor became law in 2024, when SB 616 doubled the previous minimum.5California Department of Industrial Relations. California Paid Sick Leave – Frequently Asked Questions
Two conditions apply before you can use accrued leave. You must have worked for the same employer for at least 30 days within a year, and you must have completed a 90-day employment period.4California Department of Industrial Relations. Healthy Workplace Healthy Family Act of 2014 (AB 1522) If you sub across multiple districts, each district is a separate employer with its own accrual clock. Hours at District A do not count toward your 90-day waiting period at District B.
You can use paid sick leave for your own medical appointments, a physical or mental health condition, or to care for a family member. Some districts offer more generous leave through their collective bargaining agreements, so the statutory minimum is a floor, not a ceiling.
Health Insurance Depends on Your Hours
Health insurance eligibility revolves around the federal Affordable Care Act. Under the ACA, school districts that qualify as applicable large employers must offer coverage to any employee who averages at least 30 hours of service per week, or 130 hours per month. Districts typically use the IRS “look-back measurement method,” tracking your hours over a prior period (often 12 months) to decide whether you qualify for coverage the following year.6Internal Revenue Service. Identifying Full-Time Employees
This creates a sharp divide. Long-term substitutes covering an extended leave or filling a vacancy for a full semester usually clear the 30-hour threshold. Day-to-day substitutes with irregular schedules often fall short. Some districts offer a basic plan to lower-hour substitutes, but you may have to pay the entire premium yourself.
When District Coverage Ends
If you had district health coverage during a long-term assignment and it ends because the assignment wraps up or your hours drop, you likely qualify for COBRA continuation coverage. COBRA lasts up to 18 months after a job loss or reduction in hours, with possible extensions for disability.7U.S. Department of Labor. An Employee’s Guide to Health Benefits Under COBRA The catch: COBRA premiums are steep, because you pay the full cost the district used to subsidize, plus up to a 2 percent administrative fee.
For many substitutes, a Covered California marketplace plan works out cheaper. Subsidy eligibility depends on household income, with wages, tips, and unemployment compensation all counting toward the threshold.8Covered California. What Counts as Income If your income swings from semester to semester, estimate carefully. Overestimating loses you subsidies; underestimating means you may owe money at tax time.
Bereavement Leave
Under AB 1949, California employers with five or more employees must grant up to five days of bereavement leave following the death of a spouse, child, parent, sibling, grandparent, grandchild, domestic partner, or parent-in-law. You are eligible once you have worked for the employer for at least 30 days.9California Civil Rights Department. Bereavement Leave AB-1949 FAQ The law guarantees the time off; it does not require the employer to pay for it. You can use accrued sick leave or other paid time off during the bereavement period.
Workers’ Compensation and Legal Defense
If you are injured on the job, whether from a hallway slip, a student altercation, or anything else that happens during the course of your work, you are covered by California’s workers’ compensation system, the same as any other school employee. You have up to one year from the date of injury to report the incident. Once you report it, the district must provide a claim form (DWC-1) within 24 hours. During the initial investigation period while the district evaluates your claim, you are entitled to up to $10,000 in medical treatment even before liability is officially accepted.
California Government Code Section 825 separately requires public entities, including school districts, to defend employees against lawsuits arising from acts within the scope of employment and to pay any resulting judgment or settlement. If a parent sues you over a classroom incident, the district is generally obligated to provide your legal defense and cover damages, provided you were acting within the scope of your job and cooperate with the defense. You need to report the claim to the district in writing at least 10 days before trial.10California Legislative Information. California Government Code 825
Unemployment Between Terms
Whether you can collect unemployment during summer break or winter recess turns almost entirely on one concept: reasonable assurance. If the district tells you it intends to offer substitute work when school resumes, the EDD treats that as reasonable assurance and denies your claim for the break period, even without a specific return date.11CA.gov – Employment Development Department. FAQs – School Employees
You may still be eligible if:
- The district has not offered or indicated that you will have work next term.
- The offer of future work depends on enrollment numbers, funding, or program changes.11CA.gov – Employment Development Department. FAQs – School Employees
- You earned enough from a non-school job during the base period to qualify for a claim on those wages alone.11CA.gov – Employment Development Department. FAQs – School Employees
If you are denied, do not assume the decision is final. Initial EDD determinations are sometimes wrong, particularly when your “reasonable assurance” is vague or conditional. You can appeal in writing, typically within 30 days of the mailing date on the denial notice. Read the notice for the exact deadline.
Social Security After the WEP and GPO Repeal
CalSTRS-covered positions generally do not withhold Social Security taxes. California’s participation in Social Security for public employees is governed by voluntary agreements under Section 218 of the Social Security Act, and many school districts have not extended coverage to credentialed positions.12Social Security Administration. Section 218 Agreements A career built mostly on substitute work with CalSTRS contributions can end with little or no Social Security benefit from that work.
For years, two federal provisions penalized people in this position. The Windfall Elimination Provision reduced your own Social Security benefit if you also had a public pension from non-covered work, and the Government Pension Offset could wipe out spousal or survivor benefits entirely.13Social Security Administration. Program Explainer – Windfall Elimination Provision Both hit California teachers hard.
The Social Security Fairness Act, signed into law on January 5, 2025, eliminated both the WEP and GPO. The SSA has processed retroactive adjustments back to January 2024 for affected beneficiaries.14Social Security Administration. Social Security Fairness Act – Windfall Elimination Provision (WEP) If you currently receive a reduced Social Security benefit because of a CalSTRS pension and your payment does not yet reflect the increase, contact the SSA directly.
Check Your District’s Contract
The benefits above are statutory minimums or federal requirements. Individual districts often go further through their collective bargaining agreements, offering additional paid leave, higher sick leave caps, or more favorable health insurance terms for long-term substitutes. These agreements are usually posted on the district’s website. Your district’s HR department can confirm which benefits you qualify for based on your hours and assignment type. Make that call early in the school year, not when you already need coverage.
