Homeschooling in Washington State: Requirements and How to Start

Washington State is one of the more structured homeschool environments in the country, but it is also one of the most clearly defined. The requirements are specific, there are no gray areas about who qualifies to teach, and the annual declaration process is straightforward once you know what you are doing. Here is what every Washington family needs to know before pulling their child from public school or starting from scratch.

Who Can Legally Homeschool in Washington State

Washington law (RCW 28A.225.010) requires that the parent or guardian providing instruction meet one of the following qualifications:

• Hold a current Washington State teacher's certificate
• Have 45 or more college-level quarter credits (or the equivalent in semester hours)
• Be supervised by a certificated person
• Complete a qualifying course in home-based instruction at a postsecondary institution or vocational-technical institute
• Have the district superintendent approve a different arrangement

The 45-quarter-credit rule catches many parents off guard. It means the parent-teacher needs the equivalent of about one year of full-time college coursework — not necessarily in education, just overall. If you do not meet this threshold, the supervision route is the most common workaround. Some umbrella schools and homeschool cooperatives provide certified teacher supervision for a fee.

Filing Your Annual Declaration

Each year, by September 15 (or within two weeks of the beginning of a public school quarter, trimester, or semester), you must file a Declaration of Intent to Provide Home-Based Instruction with your local school district. The form is simple — it confirms the child's name and age and whether a certificated person will supervise — but missing the deadline can create compliance headaches.

You file with the superintendent of the district where you live, not where you were previously enrolled. Moving mid-year requires a new declaration in the new district within two weeks.

Required Subjects

Washington mandates instruction in the following subject areas:

• Occupational education
• Science
• Mathematics
• Language, reading, writing, and spelling
• Social studies and history
• Health
• Appreciation of art and music

You do not need to prove mastery in each subject annually, but you must be providing instruction across all of them. There is no required curriculum — the choice of materials is entirely yours.

Annual Assessment Options

Washington requires an annual assessment of academic progress for each homeschooled student. You have two options:

Option 1: Standardized test. Have a standardized achievement test approved by the State Board of Education administered annually by a qualified individual.

Option 2: Portfolio review. A certificated teacher reviews a portfolio of the student's work and provides written assessment of progress. This is the most flexible option and popular with project-based learners.

The assessment must be made part of the child's permanent records. If the child transfers to another public or private school, forward the assessment or test scores, immunization records, and other records you keep relating to the instructional and educational activities provided to that school.

Homeschooling High Schoolers: The College Prep Layer

For families with students in grades 9–12, Washington's homeschool requirements are just the beginning of the paperwork challenge. Creating a transcript, building a school profile, and navigating Common App as the parent-counselor requires a separate framework entirely.

Washington State University, the University of Washington, and other state schools all accept homeschool transcripts, but they evaluate them differently than traditional school records. A parent-signed transcript is legal and valid — but it needs to be structured professionally to avoid raising flags during admissions review.

The United States University Admissions Framework covers this in full: how to assign Carnegie units, calculate weighted vs. unweighted GPA, write the School Profile, and complete the Common App Counselor account as a homeschool parent.

Accessing Public School Resources

Under Washington's "Running Start" program, eligible 11th- and 12th-grade home-based instruction students can enroll in participating community or technical college courses, subject to institution requirements and applicable fees. These courses can provide both high-school and college credit under program rules.

Washington law requires districts to permit eligible home-based instruction students to enroll part-time and receive ancillary public-school services, including sports, subject to district procedures and WIAA eligibility rules. Check directly with your district for its process.

Common Mistakes to Avoid

Missing the September 15 deadline. It is a hard date. If you are starting mid-year, the two-week rule runs from the beginning of a public school quarter, trimester, or semester — not simply from the first day of your own instruction.

Not documenting supervisor credentials. If you are using the supervised instruction pathway, keep written documentation of the supervising teacher's certification on file.

Confusing "review" with "submission." You do not file annual assessment results with the district under the standard home-based instruction rule, but the assessment becomes part of the child's permanent records and must be forwarded if the child transfers.

Assuming dual enrollment grades don't matter. If your high schooler takes a Running Start course and earns a C, that grade becomes a permanent part of their college transcript. It follows them to every future college and professional school application.

Washington homeschool law is genuinely reasonable once you understand the qualification tiers and annual filing rhythm. The harder challenge — for families with college-bound students — is building the documentation infrastructure that turns years of home education into a competitive admissions package.
