Education in Washington
Washington educates roughly 1.1 million public K–12 students across about 295 school districts, overseen by the elected Superintendent of Public Instruction and the Office of Superintendent of Public Instruction (OSPI). Enrollment is concentrated in the Puget Sound region.
Washington's approach has some notable features. Its school choice is largely public — it has a small, legally contested charter sector and pioneered Running Start dual enrollment, but has no private-school voucher or ESA. Uniquely, Washington approves private schools through the state; it mandates "Highly Capable" (gifted) programs; it offers the very generous, entitlement-based Washington College Grant; and it uses graduation pathways rather than a single exit test. This guide walks through it all — for the student, the family, the school, and the educator.
Who must attend school
Washington requires children ages 8 to 18 to attend school (until graduation) — and children who are 6 or 7 and already enrolled must attend regularly. Attendance can be met through a public school, an approved private school, or home-based instruction.

Pre-K in Washington
Washington's state preschool is the Early Childhood Education and Assistance Program (ECEAP) — free, high-quality preschool for eligible (largely at-risk and income-qualified) 3- and 4-year-olds. Under the Fair Start for Kids Act, Washington is moving to make ECEAP an entitlement — guaranteeing a slot for every eligible child (phasing in by around 2026–27). Washington also offers Transition to Kindergarten programs and Head Start.
Because ECEAP is eligibility-based (though expanding to an entitlement), availability depends on your child's qualifications and community — so check local options early. See our Kindergarten Readiness and Early Childhood toolkits.
Districts & charters
Washington's largest districts include Seattle, Spokane, Tacoma, Kent, Lake Washington, and Federal Way. Washington's charter-school sector is small and has been legally contested: voters approved charters in 2012, the state Supreme Court struck down the original funding in 2015, and the legislature re-authorized them in 2016. About 15 charter schools now operate, and the authorization window has been closed since 2021 — so the sector remains limited.

Private & independent schools in Washington
Washington has a solid private-school sector, concentrated in the Seattle metro and other cities, spanning several kinds of schools:
- Independent schoolsNonprofit, board-governed, tuition-funded schools (such as Lakeside, Seattle Academy, The Bush School, University Prep, and Annie Wright) — "independent" meaning not owned by a church or chain
- Catholic & parochial schoolsArchdiocese of Seattle schools and other church-affiliated schools
- Other religious schoolsChristian, Lutheran, Jewish, and more
- Specialty schoolsMontessori, Waldorf, and schools for specific learning needs
A distinctive point: unlike many states, Washington requires private schools to be approved by the State Board of Education — private schools must meet state approval requirements to operate, which is more oversight than most states provide. Many independent schools are also accredited through the Northwest Association of Independent Schools (NWAIS), a Seattle-based regional association.
Running Start & public choice
Washington's school choice is largely public — there is no private-school voucher or ESA. The signature option is Running Start:
- Running StartA pioneering dual-enrollment program (since 1993) that lets 11th and 12th graders take college courses tuition-free at Washington's community and technical colleges and several universities — earning both high school and college credit (homeschoolers are eligible too)
- Other dual creditCollege in the High School and CTE Dual Credit
- Charter schoolsA small, legally contested sector (above)
- Inter-district choiceTransfers and releases where available
So Washington families choose among schools within their district, a few charters, Running Start/dual credit, private schools, and homeschooling. See our School Types toolkit for how these compare.
Homeschooling in Washington
Washington takes a moderate approach to home-based instruction (RCW 28A.200):
- Declaration of IntentFile a Declaration of Intent to homeschool with your local district by September 15 (or within two weeks of starting)
- Parent qualificationMeet one of four options: 45 college quarter credits, a qualifying course, supervision by a certificated teacher, or being deemed sufficiently qualified by the superintendent
- InstructionProvide about 1,000 hours (or 180 days) across 11 required subjects
- Annual assessmentGive a standardized test or an evaluation by a certificated person (kept, not submitted)
Washington homeschoolers can also access public-school extracurriculars and Running Start. Parents set their own curriculum and graduation approach and issue their own diplomas. See our Homeschooling toolkit, and file your Declaration with your district (see OSPI).
Smarter Balanced & science
Washington public schools use the Smarter Balanced Assessment in English language arts and mathematics (grades 3–8 and 10) and the Washington Comprehensive Assessment of Science (WCAS) in grades 5, 8, and 11. Importantly, these tests are one of several "graduation pathway" options (below) rather than a single hard exit requirement.
Home-based students are not part of state testing (they complete their own annual assessment). See the OSPI assessment pages for current details.
Earning a Washington high school diploma
Washington's Career and College Ready graduation requirements have three parts: earn 24 credits (across English, math, science, social studies, world language, the arts, health/fitness, and CTE); complete a High School and Beyond Plan (HSBP) that guides course and career planning; and complete a graduation pathway. The pathway can be met in many ways — meeting a score on the state tests, the SAT/ACT, dual credit, AP/IB, the ASVAB, a CTE course sequence, or transition courses.

Special education & Highly Capable
Washington 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 overseen by OSPI.
Washington refers to gifted education as the Highly Capable Program, and it is comparatively well supported: districts are required to identify and serve highly capable students, backed by state funding — a stronger commitment than many states make. See our Special Education and Gifted & Talented toolkits, and verify with OSPI.
How Washington reports school performance
Washington does not use A–F letter grades or star ratings. Instead, it identifies schools for support through the Washington School Improvement Framework (WSIF) and publishes detailed data on the Washington State Report Card — reporting measures such as achievement and growth on state tests, graduation rates, English-learner progress, and school climate.
Because Washington emphasizes a support framework and a data report rather than a single grade, families should read the Report Card alongside a school visit (see our Choosing the Right School toolkit). Explore the Washington State Report Card, and find schools in our directory.
Immunizations & school entry
To enroll in a Washington school, students must show proof of required immunizations per the schedule set by the Washington State Department of Health, or a valid exemption. Requirements follow the state schedule, with additional doses at certain grades.
Washington allows medical, religious, and personal/philosophical exemptions for most vaccines — but in 2019, following a measles outbreak, Washington removed the personal-belief exemption for the MMR (measles/mumps/rubella) vaccine, so MMR now requires a medical or religious exemption only. Confirm current requirements with the Washington State Department of Health and your school district before enrolling.
The Washington College Grant & more
Washington offers one of the nation's most generous state aid programs: the Washington College Grant (WCG) is an entitlement — meaning every eligible student is guaranteed an award (not first-come, first-served) — and it can cover free or reduced tuition for students from families under an income threshold, at both colleges and approved apprenticeships/career programs. Washington also offers the College Bound Scholarship (an early commitment for lower-income students who sign up in 7th or 8th grade) and the Washington State Opportunity Scholarship (STEM/health fields).
Students apply by filing the FAFSA or WASFA by the deadlines. Use our Net Price, SAI Estimator, and Award Letter tools to plan costs, and see programs via the Washington Student Achievement Council.
Colleges & universities in Washington
Washington's public higher education includes the flagship University of Washington (UW) in Seattle (with campuses in Tacoma and Bothell), the land-grant Washington State University (WSU) in Pullman, three regional universities (Central, Eastern, and Western Washington), The Evergreen State College, and a large system of 34 community and technical colleges (overseen by the State Board for Community and Technical Colleges) — which anchor Running Start and transfer pathways.
Washington is also home to notable private institutions (Gonzaga, Seattle University, Whitman, and the University of Puget Sound among them). Explore Washington's colleges and universities in our directory.
Becoming a teacher in Washington
Washington certifies teachers through OSPI and the Professional Educator Standards Board, and — unlike Praxis states — candidates take the WEST (Washington Educator Skills Tests) and related exams (such as the NES subject tests) after completing an approved preparation program. Washington issues a Residency certificate that advances to a Professional certificate, and offers alternative routes for career changers.
Washington also provides reciprocity for many out-of-state educators. See our Teacher Certification, Praxis, and Job & Interview Tips for Educators toolkits, and the OSPI / PESB certification pages for specifics.
