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 semester credits (or equivalent quarter credits)
• Be supervised by a certificated teacher in the district or an approved private school
• Complete a course in home-based instruction at an approved institution
• Have the district superintendent approve a different arrangement

The 45-credit rule catches many parents off guard. It means the parent-teacher needs the equivalent of about three semesters of 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 beginning instruction mid-year), 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, age, and the parent's qualification — 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, writing, spelling, reading, and literature
• Social studies (history, government, geography)
• Health
• Art and music appreciation
• Washington State and United States history and government
• Physical education

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 several options:

Option 1: Standardized test. Administer a commercially available standardized test. The test must be reviewed by a qualified person — typically defined as someone with a college degree and some knowledge of learning development. Many families hire a certified teacher for this review.

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.

Option 3: Department of Children, Youth, and Families review. In certain cases, a state-approved evaluator may assess the child.

Assessment records must be maintained for three years and are subject to inspection by the school district. They do not need to be submitted proactively — keep them on file and produce them if asked.

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, homeschool students aged 16 and older can take community and technical college courses at no cost to the family. These credits count toward both high school requirements and a future college degree — a significant advantage.

Homeschool students are generally not entitled to enroll part-time in their local public school for electives or sports under state law, though some districts allow it at their discretion. Check directly with your district for their policy.

Common Mistakes to Avoid

Missing the September 15 deadline. It is a hard date. If you are starting mid-year, you have two weeks from the start of instruction — not the school year.

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." Assessments are reviewed and filed — you are not submitting test scores to the district each year. But if the district ever asks, you need to produce three years of records.

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.
