Wonder KC is a learner-driven microschool in Kansas City that follows the Acton Academy model and has served students since 2018. The day runs on Socratic discussion and self-paced work: a morning launch and core-skills block for math, reading, and writing, then an afternoon quest for hands-on projects, coding, and entrepreneurship. Listed tuition is $14,800 per year.
Students set their own pace and learn through guides rather than lectures, with a schedule that opens at 8:30 drop-off and closes with a 3:15 group meeting. Wonder KC is accredited by the International Association of Learner Driven Schools and belongs to the global Acton Academy network of more than 300 schools. The program has been operating from a temporary location while it finishes a permanent campus.
Families looking at Wonder KC in our directory should confirm the current campus, grade openings, and pricing directly. An Acton-model microschool runs differently from a conventional classroom, so a visit matters before enrolling.
Saint Louis Sudbury School is a self-directed microschool in South City St. Louis, at 3636 Texas Avenue inside the Intersect Arts Center. It serves students ages 5 to 18 under the Sudbury model, where there are no grades, tests, or homework and students help govern the school. The school is a registered nonprofit, and more than half of enrolled students receive tuition assistance.
Mixed-age groups replace grade levels here, and staff act as facilitators rather than teachers while students choose their own activities. Enrollment is flexible, from two to five days per week, full or part time. Because the school posts no fixed tuition figure, families need to ask about current rates and aid.
Read the Saint Louis Sudbury School listing for contact details. A democratic, fully self-directed model is a narrow niche, so confirm the day-to-day structure and the assistance options before applying.
Guidepost Montessori at Arbor Spring is a Montessori campus at 430 Arbor Spring in Ballwin, serving West St. Louis County families from Manchester, Ellisville, and Chesterfield. It runs three early-childhood programs: Nido for infants from six weeks, a Toddler community, and a Children's House for ages 3 to 6 that includes a kindergarten year. The campus stays open Monday through Friday from 7:00 a.m. to 6:00 p.m.
Guidepost offers year-round, extended-day programming at no extra cost, which suits working parents who need full-day coverage. The Arbor Spring campus won a Best of 2025 award in the education category from Queeny Township. Guidepost Montessori is one of three Guidepost campuses in our Missouri listings, alongside Central West End and Creve Coeur.

We picked these three Missouri microschools for variety and a verified web presence, not by a numerical score. Each school appears in the microschool.directory listings, runs a working website, and represents a different learning model and region of the state. This is an editors' pick, not a ranked league table.
Missouri lists 8 microschools across 6 cities, split between Montessori at 3 schools, learner-driven at 3, and general microschools at 2. We chose one school from each model so a parent can compare Montessori, Acton learner-driven, and Sudbury self-directed approaches side by side.
Each school's grades, model, and location were confirmed against the school's own site in 2026. Any microschool can change its program between years, so treat every detail here as a starting point and verify with the school.
Most microschools in Missouri do not publish tuition, so the honest answer is to contact each school directly. The one school in our directory that posts a price, Wonder KC in Kansas City, lists $14,800 per year. Cost depends on the model, the city, and the number of days per week, so always confirm the current figure on the school's own site.
Missouri does offer help with tuition through MOScholars, a tax-credit Empowerment Scholarship Account program that the state expanded statewide in 2025. It serves students who have an IEP or come from households at or below 300% of the free and reduced lunch income limit, with awards averaging about $6,375; families apply through the Missouri Treasurer's office, and funding is limited. Families who teach at home instead may file an optional declaration of enrollment with the recorder of deeds or local district; the Missouri DESE homeschool page outlines the rules. Ask each school about its own scholarships or sliding-scale aid.
To choose a microschool in Missouri, start with the learning model, confirm the grades and weekly schedule, tour in person, and read the enrollment terms before paying. Match the model, such as Montessori, Acton learner-driven, or Sudbury self-directed, to how your child learns best.
Ask how staff track progress, how many students share a room, and what a typical day looks like. Compare two or three schools so you can judge fit, not just price. If a term is unfamiliar, our glossary of terms defines the common microschool and homeschool models.
