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. For an HBI family, a student subject to compulsory attendance — generally age eight through 18 — must complete an assessment each year.
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 Under the Provider's Rules
The student takes a standardized achievement test evaluated by the Buros Institute of Mental Measurements. Common examples include the Iowa Assessments/ITBS, the Stanford Achievement Test (SAT-10), the California Achievement Test (CAT), the Woodcock-Johnson, and TerraNova. Administration follows the test provider's rules: a parent may administer a test such as CAT when the provider permits it, while another test may require a qualified proctor.
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 or other certifying person to review the student's academic progress. The evaluator reviews the student's work — typically a portfolio of learning artifacts — and certifies reasonable progress consistent with the student's age or stage of development.
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.225.010(4) are:
- Occupational education
- Science
- Mathematics
- Language
- Social studies
- History
- Health
- Reading
- Writing
- Spelling
- 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 beginning of any public-school quarter, trimester, or semester).
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 plan to use a popular evaluator, aim to book by March; that is planning guidance, not a statutory deadline.

What Happens If You Skip the Assessment
Washington's Becca Bill (RCW 28A.225) governs compulsory attendance. An HBI family that skips an annual assessment can be out of compliance and may later face difficulty documenting the child's educational history for an institution or a proceeding. Keep the assessment record in the family's private files rather than assuming it can be recreated later.
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 educational 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, keep these records in the family's private files:
- The student's annual test scores or the certificated 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 complete a Buros-evaluated standardized achievement test under the provider's rules, not to achieve a specific result.
Can I administer the test myself?
Not always. Administration follows the test provider's rules, and some providers permit a parent-led CAT administration. Other tests may require a qualified proctor. This is one of the reasons many families gravitate toward the certificated-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 18, subject to statutory exceptions. A 17- or 18-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 as a routine HBI filing. Keep the documentation in your own records; there is no routine submission deadline for the assessment record.
