Search for a California school hiring calendar and you will find plenty of advice and almost no sources. That is not an accident: neither the California Department of Education, nor TEACH California, nor EdJoin publishes hiring-calendar guidance for job seekers. There is no official answer to “when should I be looking.”
What is documented is the law. A handful of Education Code deadlines force districts to make staffing decisions on a fixed schedule, and everything else — when postings appear, when they are filled — happens downstream of that. So this page starts with the statute, and is careful about where the evidence stops.
How to read this page
Dates and code sections are statutory and cited to California Legislative Information. Everything about when jobs get posted is observed behaviour, not policy — no California body publishes it, so where the only evidence is out-of-state or national research, this page says so. Treat that second kind as a planning heuristic, not a rule.
The statutory clock
Four dates do most of the work.
| By March 15 | The superintendent must give written notice that it has been recommended an employee's services will not be required next year (§ 44949) — a preliminary notice opening a process, not a termination. Separately, § 44929.21 requires districts of 250+ ADA to tell second-year probationary teachers whether they will be reelected; silence means deemed reelected. Since AB 438 took effect in 2022, permanent classified staff follow materially the same track (§ 45117). |
|---|---|
| On or before May 7 | Where a hearing was requested, the administrative law judge's proposed decision goes to the board (§ 44949). |
| Before May 15 | Final notice of termination must be given (§ 44955). The statute says “before the 15th of May,” so May 14 is the last day, though nearly every secondary source writes “by May 15.” Without the notices and a right to a hearing, the employee is deemed reemployed. |
| By July 1 | The governing board must adopt a budget for the coming fiscal year (§ 42127). Until it does, a district's final position count is provisional. |
Why notices do not simply become job openings
This is the step most advice skips. Employees who receive March notices do not vanish from the workforce — they gain recall rights that outrank outside applicants.
- Permanent certificated staff hold a 39-month preferred right to reappointment (§ 44956); probationary staff hold 24 months, behind them (§ 44957).
- Classified employees hold 39 months, and the statute says the right “shall take preference over new applicants” (§ 45298).
- Temporary staff and long-term substitutes who served at least 75% of the year are to be reemployed into vacant positions (§ 44918), though day-to-day on-call substitutes are expressly excluded.
The numbers involved are large: in March 2026 the California Teachers Association reported more than 1,900 preliminary notices to its members, and the California School Employees Association more than 2,700 to classified staff. But two consequences follow. Preliminary notice counts are a poor proxy for job openings — districts routinely issue more than they act on and rescind a large share before May, and those that stand create recall obligations rather than vacancies. And a role advertised in spring may still be filled from a recall list before an outside application is read.
When postings actually appear
Here the honest answer is that California publishes no data, so what follows is inference and out-of-state evidence, labelled as such.
March through May is where the law puts the decisions. County offices of education behave accordingly, and recruitment fairs cluster in March. Note the caveat the county offices give themselves: the Sacramento County Office of Education's own March fair materials point out that districts do not generally know their actual vacancies until around April 1. A March fair is for meeting districts, not for applying to confirmed openings.
On the shape of the posting season, the closest thing to hard evidence is not Californian. Research by Goldhaber and colleagues using Washington State data describes a teacher-hiring season running roughly March through August. TNTP's national work found that urban districts historically made a large share of their offers in July and August. Both are suggestive for California; neither is California data — so treat a confident “most jobs are posted May to July” as folklore, because that is what it is.
August is the best-evidenced stretch, though less as a posting wave than as a visible shortfall: California districts have repeatedly begun the school year with unfilled positions, reported by EdSource in 2016 and again in 2022, and by the San Francisco Examiner in 2023, with named districts still recruiting into the opening weeks. Openings exist in August, and the field competing for them is thinner because many candidates have stopped looking.
Districts dislike this as much as candidates do. Peer-reviewed work by Papay and Kraft — again out-of-state — associates late hiring with measurably weaker outcomes, on the order of 0.042 standard deviations in mathematics. Late hiring is a problem districts are trying to fix, not a preference.
Substitute work runs on its own clock. The Commission on Teacher Credentialing states plainly that “many employers hire substitutes year-round.” Classified postings — instructional aide, paraeducator, office, transportation, food service, custodial — also appear throughout the year rather than in a season.
Where the openings are concentrated
Two things are true at once: enrollment is falling, and parts of the system remain short of fully credentialed teachers.
The California Department of Education reported 5,731,260 students in 2025–26, down 1.3% — a fall of 74,961 and the largest since 2021–22. Transitional kindergarten is the exception, up 20.1% as the grade expands, and a genuine source of new positions running against the trend.
On supply, the Commission on Teacher Credentialing reported in April 2026 that California issued 20,102 new teaching credentials in 2024–25, up 16% and a second consecutive annual increase, with preparation-program enrollment at 40,388 — up 4.6% year on year but still about 9% below 2020–21. Emergency-style permits totalled 7,996: down 5.2% on the year, but roughly two and a half times the 2020–21 figure.
The gaps concentrate by subject. Learning Policy Institute figures for 2024–25 put the share of teachers fully credentialed for the subject they teach at 57% in computer education, 66% in career technical education, 68% in art, and about 70–71% in science, mathematics and world languages. Special education is sharpest: 51% of newly issued Education Specialist credentials went to people on emergency-style permits, and a further 24% to interns. If you are credentialed in one of those areas, seasonality matters less — those roles stay open, reopen, and appear outside any wave.
How to use this
- Be application-ready before April — credential status, transcripts, references and your EdJoin profile finished — so a posting with a short window is something you can act on the same day.
- Use March for reconnaissance. County recruitment fairs, and learning which districts are moving, while remembering that firm vacancy numbers generally are not known until around April.
- Watch continuously from spring through August rather than betting on one month. The evidence does not support a single peak you can wait for.
- Do not write off August. It has the best evidence behind it and the smallest field.
- Apply early inside a posting's own window. Applications that arrive first are often read first, and a posting marked “Until Filled” can close as soon as a district has enough candidates.
Since nobody publishes the calendar, the practical answer is not to memorise one. It is to be ready early, and to have postings come to you across the whole span rather than guessing which month to start refreshing.
Watch the whole span, not one month
Save a search for the roles and districts you want. AlertEd sends a free daily digest for each saved search, so you do not have to guess which month to start looking.
