California Education Guide

Education in California

California runs the nation's largest public education system — roughly 5.8 million K–12 students across about 1,000 school districts and 58 county offices of education, overseen by the California Department of Education (CDE), the elected State Superintendent, and the State Board of Education. Funding flows through the Local Control Funding Formula (LCFF), and each district sets priorities through a Local Control and Accountability Plan (LCAP) — a strong local-control model.

Several things make California distinctive. It has no private-school voucher or ESA program (voters have repeatedly rejected them), relying instead on public choice and a large charter sector. It has moved to universal Transitional Kindergarten. It rates schools with a color-coded Dashboard rather than letter grades, and it has one of the nation's strictest immunization laws. This guide walks through it all — for the student, the family, the school, and the educator — and points to the official source throughout.

Who must attend school

In California, children ages 6 to 18 are subject to compulsory full-time education (Education Code § 48200) — enrollment is required once a child turns 6 by September 1. Notably, kindergarten is not compulsory (a child may start at 5, but isn't required to until age 6). Attendance can be met through public school, private school (including a home-based private school), or an approved arrangement.

Universal Transitional Kindergarten (TK)

California has made a landmark early-childhood investment: Transitional Kindergarten (TK) is now universal as of the 2025–26 school year, available free to all children who turn 4 by September 1 at their local public school (the phase-in that began in 2012 reached its finish line). TK is a play-based first year of a two-year kindergarten experience and is part of California's broader Universal Prekindergarten (UPK) initiative.

Alongside TK, California offers the California State Preschool Program (CSPP) for income-eligible families, Head Start, and private early-care providers. To support TK, the state created a new PK–3 Early Childhood Education Specialist Credential. See our Kindergarten Readiness and Early Childhood toolkits, and confirm TK details with the CDE.

Districts & charters

California's roughly 1,000 school districts range from the enormous to the tiny. The Los Angeles Unified School District is the second-largest in the nation, followed by districts such as San Diego Unified, Fresno Unified, and Long Beach Unified. California also has a large charter-school sector (among the biggest in the country), though charter authorizing and renewal have become more tightly regulated in recent years.

Public-school choice within the system runs through intradistrict and interdistrict transfers, magnet programs, and open-enrollment options (subject to district rules and capacity). Find California public and charter schools in our schools directory.

Private & independent schools in California

California has one of the country's largest and most varied private-school sectors, spanning:

• Independent schoolsNonprofit, board-governed, tuition-funded schools — including nationally known day schools (Harvard-Westlake, Marlborough, Polytechnic, Crossroads, Head-Royce, Menlo, The Harker School, Castilleja) and boarding schools (Thacher, Cate, Webb)
• Catholic & parochial schoolsA very large network across the Archdioceses of Los Angeles, San Francisco, and San Diego and other dioceses
• Other religious schoolsChristian, Jewish, and other faith-based options
• Specialty schoolsWaldorf (California has many), Montessori, and schools for specific learning needs

A key point: California does not accredit private schools, but it requires them to file an annual Private School Affidavit with the state (a registration, not an approval). Accreditation is voluntary — commonly through the Western Association of Schools and Colleges (WASC) or the California Association of Independent Schools (CAIS). Because California has no voucher or ESA, private schools are funded by tuition and their own financial aid. Families should ask about a school's accreditation, curriculum, and outcomes directly.

How choice works in California

California's approach to school choice differs sharply from voucher/ESA states: it has no private-school voucher or education savings account program, and California voters have rejected voucher ballot measures more than once. Public dollars do not follow students to private schools.

Instead, California families choose among public options: charter schools (a large sector), magnet schools, intradistrict transfers (choosing another school within your district), and interdistrict transfers (attending a school in another district, with approval). Public independent study and homeschool charter programs are also popular (see Homeschooling). See our School Types toolkit for how these options compare.

Homeschooling in California

An important quirk: California has no legally defined "homeschool." Instead, families educate at home through one of four legal arrangements:

• 1 · Private School Affidavit (PSA)The most common route — establish your own home-based private school by filing a PSA with the CDE each year (the filing window is October 1–15). No state testing, no minimum hours, and no curriculum approval (Ed. Code §§ 48222, 33190).
• 2 · Private School Satellite Program (PSP)Enroll through an umbrella private school that files for you and provides support.
• 3 · Public charter / independent studyEnroll in a public independent-study or homeschool charter — your child is a public-school student (keeping IEP services and accessing per-pupil funds) but must take state tests and follow an independent-study agreement.
• 4 · Credentialed private tutorInstruction by a California-credentialed tutor.

Families using the PSA or PSP operate as private schools — outside CAASPP testing and the state accountability system, with parents solely responsible for progress. Those in a public charter gain funding and services but take the same state tests as other public-school students. See our Homeschooling toolkit, and confirm the PSA process with the CDE.

CAASPP & the ELPAC

California public schools use CAASPP (the California Assessment of Student Performance and Progress) — the Smarter Balanced summative tests in English language arts and mathematics in grades 3–8 and 11 — plus the California Science Test (CAST) at designated grades. English learners take the ELPAC to measure English-language proficiency.

Homeschoolers under a PSA/PSP are not part of CAASPP, while students in public charter/independent-study programs test like other public-school students. See the CDE assessment pages for current details.

Earning a California high school diploma

California sets statewide minimum course requirements for graduation (Ed. Code § 51225.3) but leaves districts to set their specific credit requirements, so exactly what it takes to graduate varies by district — and many districts require more than the state minimum. California does not require a high-stakes exit exam (the former CAHSEE exit exam was eliminated in 2015).

• State minimumsEnglish, math (incl. Algebra I), science, social studies, arts/world language/CTE, PE
• Districts set creditsLocal requirements often exceed the state minimum
• No exit examCAHSEE was eliminated in 2015
• "A–G" for UC/CSUMeeting A–G course requirements is key for admission to UC/CSU

Special education & gifted

California serves students with disabilities under the federal IDEA, providing eligible students a free appropriate public education through an IEP in the least restrictive environment, with full procedural safeguards (mediation and due process). A distinctive California structure: services are coordinated through regional SELPAs (Special Education Local Plan Areas), which group districts to plan and deliver special education.

On gifted education, California's GATE (Gifted and Talented Education) program is no longer a categorical state mandate — funding was folded into the LCFF, so local districts decide whether and how to identify and serve gifted students. Availability therefore varies by district. See our Special Education and Gifted & Talented toolkits, and verify with the CDE.

The California School Dashboard

Rather than assigning A–F letter grades, California reports school quality through the California School Dashboard — a color-coded system (from red to blue) that reports multiple measures for each school and district, including academic achievement and growth, graduation rate, chronic absenteeism, suspension rate, English-learner progress, and college/career readiness. The Dashboard is tied to the LCFF/LCAP local-control framework.

Because it's a multi-measure, color-coded dashboard, it gives a fuller (if less simple) picture than a single grade. Explore the California School Dashboard, and find schools in our directory (see our Choosing the Right School toolkit).

Immunizations & school entry

California has among the strictest school immunization laws in the nation. Under SB 277 (2016), California eliminated the personal belief exemption, and there is no religious exemption — for classroom-based public and private schools, only a medical exemption is available (and medical exemptions were further tightened by SB 276). Required vaccines follow the state schedule, with additional requirements at 7th-grade entry.

(Note: children in a home-based private school with no classroom-based instruction are not subject to the immunization requirement — but must comply if they enroll in a classroom setting.) Confirm current requirements at California's official Shots for School site and with your school district before enrolling.

Cal Grant & state aid

California offers substantial state financial aid. The flagship Cal Grant program provides need- and merit-based grants to eligible California students at UC, CSU, community colleges, and many private/career colleges. California also offers the Middle Class Scholarship (aid for middle-income UC/CSU students) and the California College Promise (which can make the first year(s) of community college free at participating colleges).

Students apply by filing the FAFSA (or the California Dream Act Application) and meeting Cal Grant requirements by the deadlines (a key deadline is typically March 2). These programs are administered by the California Student Aid Commission (CSAC). Use our Net Price, SAI Estimator, and Award Letter tools to plan costs, and see csac.ca.gov.

California's three public systems

California's public higher education, shaped by its landmark Master Plan, is organized into three tiers: the University of California (UC) — 10 research campuses including Berkeley, UCLA, and San Diego; the California State University (CSU) — 23 campuses and the largest four-year system in the country; and the California Community Colleges (CCC) — 116 colleges, the largest higher-education system in the nation, with strong transfer pathways (including guaranteed-transfer agreements) into UC and CSU.

California also has many prestigious private colleges and universities (Stanford, USC, Caltech, and more). Explore California's colleges and universities in our directory.

Becoming a teacher in California

California credentials teachers through the Commission on Teacher Credentialing (CTC), and — unlike Praxis states — candidates typically demonstrate basic skills via the CBEST and subject-matter competence via the CSET (California-specific exams), alongside an approved preparation program and a teaching performance assessment. Teachers earn a Preliminary credential, then clear it to a Clear credential through induction.

To support universal TK, California created a new PK–3 Early Childhood Education Specialist Credential. California offers intern and alternative pathways and reciprocity for many out-of-state educators. See our Teacher Certification, Praxis, and Job & Interview Tips for Educators toolkits, and the CTC for specifics.
