RCW 28A.200 and the OSPI Pink Book: Washington's Homeschool Law Explained

If you have started researching Washington homeschool law, you have probably come across references to RCW 28A.200 and something called the "Pink Book." Both are worth understanding directly, not just through summarized versions — because the statute and the OSPI document together define the actual legal framework you are operating under.

Here is what each document says, what it means practically, and where families often misread it.

What Is RCW 28A.200?

RCW 28A.200 is the chapter of the Revised Code of Washington that governs home-based instruction. It sits within Title 28A, the education code, and was originally established by Chapter 441 of the 1985 Laws of Washington (Senate Bill 3279). It has been amended several times since.

The chapter is short — several pages of statutory text — but it defines all the core obligations for home-based instruction in Washington:

• The four parent qualification pathways
• The eleven required subjects
• The annual assessment requirement (standardized test or certificated teacher evaluation)
• Explicit limitations on what the state can require of homeschoolers
• Prohibition on disclosure of private homeschool records

The most important provision in RCW 28A.200 for most families is RCW 28A.200.020, which spells out the four legal duties of an HBI parent. Understanding this section means you understand what Washington actually requires — no more, no less.

What RCW 28A.200.020 Actually Says

The four duties established by this statute:

1. Parent must be qualified. Under RCW 28A.225.010(4), the parent providing instruction must hold 45 quarter college credits, have completed a qualifying home-based education course, have a certificated teacher supervise instruction, or have superintendent approval.

2. File a Declaration of Intent. Annual notification to the local school district superintendent that the child will receive home-based instruction. Due by September 15th, or within two weeks of the start of the public school year.

3. Provide instruction in eleven required subjects. Occupational education, science, mathematics, language, social studies, history, health, reading, writing, spelling, and the appreciation of art and music.

4. Annual assessment. Either a Buros Institute-approved standardized test or a written evaluation by a Washington State certificated teacher currently working in the field of education.

That is the complete list of mandatory duties. Four items. Everything else — curriculum choices, daily schedules, instructional hours, teaching methodology — is entirely at the parent's discretion.

What RCW 28A.200 Explicitly Prohibits the State from Requiring

This is the part many families do not read carefully, and it matters. The statute contains explicit prohibitions on state overreach into home-based instruction:

• The State Board of Education cannot require home-based students to meet state student learning goals or master Essential Academic Learning Requirements (EALRs).
• The state cannot require home-based students to obtain a certificate of mastery.
• OSPI cannot mandate standardized portfolio formats or specific documentation systems.
• The state cannot access or require disclosure of a family's private homeschool records.

These limitations mean that district staff who ask for curriculum plans, daily schedules, or portfolio previews before the annual assessment are going beyond what the law authorizes. The DOI is a notice, not an application for approval. Your records are yours.

What Is the OSPI Pink Book?

"The Pink Book" is the informal name for OSPI's publication "Washington State's Laws Regulating Home-Based Instruction," a document produced by the Office of Superintendent of Public Instruction. It is the state's official explanatory guide to RCW 28A.200 and related statutes.

The Pink Book is not law. It is an official interpretation and explanation of the law, written primarily for district administrators and school district personnel who need to understand how to interact with homeschooling families. It happens to be the most thorough single document explaining Washington's HBI requirements, which is why it has become a standard reference for homeschooling parents as well.

The current version includes:

• The full text of the relevant statutes and WAC provisions
• Plain-language explanations of each requirement
• Sample forms (Appendix A1 — Declaration of Intent; Appendix A2 — Part-Time Attendance and Ancillary Services request)
• Guidance on what districts can and cannot require from HBI families
• Information on accessing part-time public school enrollment and ancillary services

The Tone Problem

The Pink Book's main limitation for homeschooling parents is its audience. It was written for bureaucrats, and it reads like it. Dense statutory citations, passive voice, and legal hedge language throughout.

Two things in particular cause confusion when parents read it for the first time:

The "liberal construction" clause: The statute states that the eleven required subjects shall be "liberally construed" because home-based instruction is "less structured and more experiential than instruction normally provided in a classroom setting." This is good news — it means Washington intentionally gives parents flexibility in how they interpret the subject list. But parents often read "liberally construed" as something vague and worrying rather than as the explicit permission it is.

The assessment language: The Pink Book describes the annual assessment requirement accurately, but the context of truancy and compulsory attendance around it can make the assessment sound like a high-stakes examination with automatic consequences. In reality, if an assessment reveals that a child is not making reasonable progress, the legal response is that the parent must "make a good faith effort to remedy any deficiency" — there is no automatic state intervention, no loss of homeschooling rights, and no threshold score required. The state cannot penalize a child for low test scores on an HBI assessment.

What the Pink Book Does Not Provide

OSPI does not include ready-to-use portfolio templates, subject tracking sheets, or assessment preparation tools in the Pink Book. The document tells you what you are required to do; it does not give you the systems to do it.

This is the gap that Washington homeschooling families run into after their first read-through. They understand the law clearly enough — file the DOI, cover the eleven subjects, get an annual assessment — but the practical question of how to document all of this throughout the year is left entirely to the parent.

Reading the Law Directly: Where to Find It

The full text of RCW 28A.200 is publicly available at app.leg.wa.gov. Search "28A.200" in the RCW search and the chapter comes up with all subsections. RCW 28A.225.010 is the companion statute covering compulsory attendance and the parent qualification provisions.

The current version of the Pink Book is available as a PDF on the OSPI website (ospi.k12.wa.us), under Student Success > Learning Alternatives > Home-Based Instruction. The document is updated periodically; if you downloaded a version more than a year ago, it is worth checking whether a newer edition has been released.

OSPI Bulletin 025-23, released in August 2023, is also worth reading for its clarification of the distinction between home-based instruction and Alternative Learning Experiences. The bulletin explicitly separates the two legal frameworks, which helps families who have been using a Parent Partnership Program understand the difference between their current status and true HBI.

Practical Implications

Understanding RCW 28A.200 and the Pink Book does not require a law degree, but it does reward close reading. The core framework is:

1. Qualify yourself (once)
2. File the DOI annually (by September 15th)
3. Cover the eleven subjects throughout the year
4. Complete the annual assessment (test or portfolio review)

What makes the system manageable is the documentation question. The law tells you what to accomplish; your record-keeping system determines how painlessly you can demonstrate it. Parents who document throughout the year — with a reading log, activity tracker, writing samples, and subject coverage notes — walk into their annual assessment with confidence. Those who try to reconstruct a year's worth of learning in April find it considerably more stressful.

The Washington Portfolio & Assessment Templates are built directly around what RCW 28A.200 requires — all eleven subjects by their legal names, the annual assessment format that certified teachers expect, and the compliance calendar that keeps the DOI deadline and assessment window from sneaking up on you.

If you want to go straight to the source before downloading anything, read RCW 28A.200.020 and the relevant sections of the Pink Book. Then come back and decide whether building that documentation system yourself or starting with pre-built, WA-aligned templates is the better use of your time.
