How to Start a Microschool in Washington State

Seattle Public Schools is closing buildings and dismantling its Highly Capable cohort programs. Independent school tuition on the Eastside has passed $32,000 a year. Military families arriving at JBLM mid-year are discovering public enrollment waitlists that can stretch months. The result: more Washington families than ever are trying to figure out how to start a microschool — a small, intentional learning group — on their own terms.

The problem is that Washington State law makes this harder than it looks. Getting the structure wrong doesn't just waste time; it can expose families to truancy investigations or force the group to register as an approved private school with all the regulatory overhead that entails.

This guide walks through the legal framework, the structural options available to Washington families, and the practical steps to launch a compliant, functional microschool or learning pod.

Why Washington's Law Matters More Here Than in Other States

Most states have carved out explicit space for microschools, pod schools, or cooperative home education arrangements. Washington has not.

Under RCW 28A.200.010, home-based instruction (HBI) is defined as education "provided by a parent, educating his or her child only." The Washington Homeschool Organization (WHO) interprets this plainly on their FAQ: hiring a teacher to instruct other families' children is not considered homeschooling under Washington law. It would need to be an approved private school.

This creates the central structural question every Washington microschool founder must answer before doing anything else: Are you operating under HBI, or are you operating as a private school?

The answer determines everything: whether you need any registration, whether parents can legally drop off their children, and whether you can hire a paid instructor.

The Two Legal Pathways

Pathway 1: The Parent-Led Co-operative (HBI Model)

Under this model, each family maintains its own individual HBI status. No family is "hiring" an instructor to teach other families' children. Instead, parents rotate teaching responsibilities across the group — each parent is teaching their own child on their day, with other children present as a social and academic benefit.

This model is legally sound under Washington law but comes with operational constraints. Parents cannot fully drop off their children and leave. At least one parent from each family must be present or nearby during instruction. The group cannot hire an independent, non-parent teacher as the primary instructor.

It works best for: 3-6 families who can coordinate schedules, share teaching days across the 11 required subjects, and remain engaged participants rather than passive clients.

Pathway 2: Approved Private School Under RCW 28A.195

If families want a true drop-off microschool where a hired instructor teaches other people's children, Washington requires registration as an approved private school under RCW 28A.195.010. This isn't a licensing process with inspections — it's primarily a notification and record-keeping requirement — but it does impose ongoing obligations: maintaining attendance records, meeting the same annual school days requirement as public schools (180 days), and ensuring the instructor is qualified.

Many small microschool groups operating in Washington's cities are registered under this pathway. Lakeside School was reportedly exploring a satellite micro-school model under exactly this structure. The Washington Private School Extension Program is one mechanism families use to affiliate with an existing approved private school rather than registering independently.

Understanding which pathway fits your group is the first decision you make. Everything downstream — legal agreements, financial structure, teacher contracts — flows from it.

Step 1: Confirm Your Legal Structure

Before recruiting families or signing leases, hold a planning meeting to answer these questions:

• Will parents be present during instruction, or will this be a drop-off arrangement?
• Do you intend to hire a paid instructor who is not a parent in the group?
• How many families will participate, and how are teaching duties shared?

If parents will be present and rotating teaching responsibilities, you are operating a parent-led co-op under HBI. If the answer involves drop-off and a hired instructor, you need to understand the RCW 28A.195 pathway before proceeding.

Step 2: File Your Declaration of Intent

Each participating family must file an annual Declaration of Intent (DOI) with their local school district before beginning home-based instruction. This is required under RCW 28A.200.010 regardless of whether the family is participating in a group arrangement or teaching entirely alone.

The DOI must be filed by September 15 each year, or within two weeks of withdrawing a child from public school. If you are mid-year, file immediately after withdrawal. The school district does not need to approve the DOI — it is a notification, not an application.

The DOI covers: the parent's name, the child's name and grade level, the address where instruction will occur, and the parent's qualifying credential (one of four pathways under Washington law).

Step 3: Confirm Parent Qualifications

Washington law under RCW 28A.200.020 requires the parent providing instruction to meet one of four qualifications:

1. Hold a valid Washington State teaching certificate
2. Possess 45 college credits (any major, from any accredited institution)
3. Be supervised by a certificated person for at least one hour per week
4. Complete an approved parent qualifying course offered by an approved private school

If you have a bachelor's degree, you have met the 45-credit requirement. If not, the parent qualifying course is typically the fastest route — WHO and approved private schools in Washington offer these. The supervising teacher option is commonly used in extension program arrangements.

Step 4: Cover Washington's 11 Required Subjects

RCW 28A.200.020 requires that home-based instruction be in the following subjects: reading, writing, spelling, language, mathematics, science, social studies, history, health, occupational education, and art or music appreciation.

For a group setting, this is an organizational challenge, not an academic one. A single well-designed project — building a raised garden bed, for example — simultaneously satisfies math (measuring and calculating materials), science (plant biology and soil composition), occupational education (tools and construction), and history (connecting to agricultural history). Well-structured unit studies allow a microschool to cover multiple subjects efficiently without a rigid block schedule.

The key is documentation: each family needs to be able to show, at assessment time, which subjects were covered and through what activities.

Step 5: Establish Your Governance Documents

This is where most informal pods fail. Without written agreements covering shared finances, scheduling expectations, behavioral standards, and exit procedures, the group typically fractures within 3-6 months.

At minimum, a Washington microschool group needs:

A Participation Agreement covering: attendance expectations, cost-sharing for materials and any contracted instruction, decision-making processes, notice period for leaving the group, and behavioral standards for students and parents.

A Tutor or Co-Teacher Agreement if you are bringing in any paid instructor, even a parent who is being compensated for leading sessions. This document should clarify that the instructor is not providing care, but instruction — an important distinction for daycare licensing purposes.

A Hosting Agreement if sessions rotate between private homes, covering liability acknowledgment and house rules.

The Washington Homeschool Organization explicitly does not provide these documents or advise on pod governance. Etsy planners and generic homeschool templates don't include them. This is one of the most significant gaps in available free resources for Washington families attempting to formalize a group arrangement.

Step 6: Plan Your Assessment Strategy

Washington law requires an annual academic assessment for all HBI students. Families can fulfill this requirement through standardized testing or a written progress assessment prepared by a certificated person.

For a microschool group, coordinating assessments in advance simplifies the end-of-year process significantly. If you are using the certificated-person supervision pathway for parent qualification, that same supervisor is often a natural fit to provide the written assessment.

Testing options approved in Washington include the Iowa Test of Basic Skills, the Stanford Achievement Test, the CAT-E, and others. If families prefer non-test evaluation, they need to identify a certificated educator who will review portfolios and write assessments. The Washington Homeschool Portfolio guide covers documentation practices in detail.

Common Mistakes Washington Microschool Founders Make

Operating a drop-off pod under HBI. If parents are leaving their children with a non-parent instructor and going to work, that is not home-based instruction under Washington law. It likely requires daycare licensing and private school registration. Many groups discover this only when they receive a complaint.

Skipping governance documents. Financial disagreements and scheduling conflicts are the leading causes of microschool group failure in the first year. Written agreements prevent these from becoming relationship-ending disputes.

Treating WHO's co-op directory as a legal guide. WHO explicitly excludes drop-off programs from their directory and discourages the micro-school model for families who want to hire external instructors. Their guidance reflects a conservative interpretation of the law and is not a complete picture of what is legally permissible under the private school pathway.

Using Reddit or Facebook for legal structure decisions. Forum advice on whether you need a daycare license, private school registration, or nothing at all is wildly inconsistent. Parents have received confidently stated but flatly incorrect advice in both directions.

Washington Microschool Resources

The Washington Micro-School & Pod Kit provides the complete operational framework for launching a legal, functional group in Washington State — including the decision tree for HBI co-op versus private school pathway, Declaration of Intent templates, the 11-subject tracking matrix, pod governance agreements, and tutor contract templates. It covers the specific RCW codes, the OSPI Pink Book requirements, and the practical steps for both the parent-led co-op model and the RCW 28A.195 private school registration pathway.

Washington families attempting to build a sustainable microschool don't need a $150-per-hour educational consultant or a franchise model that takes 32% of tuition revenue. They need the right legal and operational framework — one built specifically for Washington's law, not recycled from Texas or Arizona.

Starting a microschool in Washington is entirely possible. Getting the structure right from the beginning makes the difference between a group that thrives for years and one that collapses under the first legal question or interpersonal dispute.
