Washington Homeschool Testing Requirements: Your Annual Assessment Guide

Your child turns eight, you file the Declaration of Intent with your school district, and then a question hits you: what exactly does Washington State require for the annual assessment? It is not complicated once you understand the two options, but the consequences of skipping it are serious enough that you need to get this right from the start.

Washington is one of roughly 25 states that mandates annual academic assessment for homeschooled students. The legal basis is RCW 28A.200.010, which requires home-based instruction families to provide an annual assessment of the student's academic progress. Every student who is subject to compulsory attendance — meaning age eight and up — must complete this every year, without exception.

The Two Assessment Paths Washington Allows

Washington law gives families a genuine choice between two distinct options. Neither is inherently better; they suit different family styles, different grade levels, and different documentation situations.

Option 1: A Standardized Test Administered by a Qualified Person

The student takes a nationally normed standardized test, administered by someone who meets specific qualifications — a certificated teacher, or a person meeting the teacher qualification requirements under RCW 28A.200.010. Common tests used by Washington homeschool families include the Iowa Tests of Basic Skills (ITBS), the Stanford Achievement Test (SAT-10), the California Achievement Test (CAT), and the Woodcock-Johnson. The test must be administered by a qualified person, not by the parent teaching the child.

There is no minimum score required. Washington law does not set a passing threshold. The requirement is participation and documentation of the result — not performance above a specific percentile.

Option 2: An Assessment by a Washington State Certificated Teacher

The parent arranges for a Washington State certificated teacher to evaluate the student's academic progress. The teacher reviews the student's work — typically a portfolio of learning artifacts — and issues an evaluation letter confirming that the student has received instruction in Washington's eleven mandated subjects and is making reasonable academic progress.

This option has grown significantly in popularity among families using Charlotte Mason, unschooling, or project-based approaches, because it allows the education itself to be assessed rather than forcing a test-taking format that may not reflect how the child actually learns.

What Counts as Washington's Eleven Required Subjects

This is where many families panic unnecessarily. Washington's eleven mandated subjects under RCW 28A.200.010 are:

1. Occupational education
2. Science
3. Mathematics
4. Language
5. Social studies
6. History
7. Health
8. Reading
9. Writing
10. Spelling
11. Appreciation of art and music

Two points are worth internalizing. First, the Washington Homeschool Organization (WHO) and OSPI have both clarified that these provisions are to be "liberally construed" — the law explicitly acknowledges that home-based instruction is less structured and more experiential than classroom instruction. Second, you do not need to teach each subject as a separate class every day. A single project — building a birdhouse, cooking a meal from a foreign country, hiking a trail — can and does satisfy multiple subjects simultaneously. The documentation challenge is showing that coverage occurred, not that you ran a traditional school schedule.

When the Assessment Must Happen

Washington law does not specify a calendar date by which the annual assessment must be completed. However, most families align with the school year rhythm, completing their assessment in the spring before the new Declaration of Intent is filed by September 15th (or within two weeks of the start of the public school semester, whichever comes first).

Practically speaking, families who choose the standardized test option typically schedule testing between March and June. Families using the teacher evaluation option often compile a portfolio in spring and schedule an evaluator session in May or June.

The key operational point: do not leave this until August. Qualified evaluators and test administrators book up in late spring. If you wait until the end of summer and cannot find an available evaluator before September, you are in a difficult position legally.

What Happens If You Skip the Assessment

Washington's Becca Bill (RCW 28A.225) governs compulsory attendance. If a child subject to compulsory attendance is not enrolled in public school and the home-based instruction family cannot demonstrate compliance with assessment requirements, the school district has grounds to initiate truancy proceedings. This is not a theoretical risk — it is the mechanism that makes Washington's moderate regulatory environment actually function.

More practically, if you skip the annual assessment consistently and your family later needs to document educational history for Running Start enrollment, college admissions, or a military background check, you will have significant gaps in your official record. Retroactively filling those gaps is far harder than maintaining documentation in real time.

The Documentation You Need to Keep

Regardless of which assessment path you choose, Washington law requires you to maintain:

• The student's annual test scores or the certified teacher's evaluation letter
• Immunization records
• Any other records relating to instructional and educational activities

There is no prescribed format for how you keep instructional records. OSPI does not provide a standard portfolio template. The Washington Homeschool Organization provides excellent legal guidance but explicitly does not supply done-for-you organizational tools.

This is the gap most families fall into: they understand what they are supposed to document but have no systematic structure for capturing it throughout the year. When spring arrives and an evaluator asks to review a year's worth of work, a shoebox of loose papers from October through March is not going to create a confident assessment session.

Building a consistent documentation habit in September — when you file the DOI and start a new school year — means your spring assessment becomes a quick review of an organized record rather than a frantic reconstruction of a year's learning.

The Washington Portfolio and Assessment Templates toolkit at /us/washington/portfolio is built specifically around Washington's eleven required subjects, the non-test evaluation process, and the documentation structure certificated teachers expect to review. If you want a system that matches the legal framework rather than a generic national planner, that is the place to start.

Frequently Asked Questions

Does my child have to pass the standardized test?

No. Washington sets no minimum score or percentile requirement. The obligation is to take an approved test administered by a qualified person, not to achieve a specific result.

Can I administer the test myself?

No. The test must be administered by a qualified person who is not the parent doing the primary instruction. This is one of the reasons many families gravitate toward the certified teacher evaluation option — it gives them more flexibility in how the assessment is structured.

What if we use an Alternative Learning Experience (ALE) or Parent Partnership Program?

ALE students are enrolled in a public school program. The district manages assessment compliance for ALE participants. If you are in a true HBI arrangement — privately funded, parent-directed, not enrolled in any district program — then the annual assessment requirement applies to you fully.

Is there an age at which the assessment requirement ends?

Washington compulsory attendance applies through age 17 (or high school graduation). A 17-year-old who has not graduated and is not enrolled in a public or approved private program is still subject to HBI requirements, including annual assessment.

Do I need to submit the results to the school district?

No. Washington does not require you to submit assessment results to your local school district. You keep the documentation in your own records. The legal exposure comes if a truancy proceeding is initiated and you cannot produce evidence of compliance — not from a submission deadline.
