    Frequently asked questions

    How many Montessori schools are in San Bruno?

    San Bruno, California has 2 Montessori schools in our directory as of November 2026; 2 of them have Google reviews. We only list schools that show evidence of a Montessori program.

    How much does Montessori school cost in San Bruno?

    None of the 2 schools here publish tuition, so we don't show a range for San Bruno; we never estimate a price a school hasn't published. Most Montessori schools share fees on request, and you can ask about tuition in a free tour request.

    Which Montessori program is right for my child's age?

    Montessori classrooms group children in three-year age spans: Toddler or Nido (about 18 months to 3 years), Casa / Primary / Children's House (3 to 6), Lower Elementary (6 to 9) and Upper Elementary (9 to 12). Not every school offers every stage. Each school's page lists its programs; ask about openings for your child's age when you book a tour.

    How do I book a tour of a Montessori school in San Bruno?

    On MontessoriCity, add the schools you like to your tour list and send one free tour request (montessoricity.com/book-tour). Each school replies to you directly with tour times, and you can compare replies, tuition and tour dates in a free parent dashboard. It costs families nothing, and you can pick as many schools as you want.

    How are the Montessori schools in San Bruno ranked?

    Only by Google rating and number of Google reviews, using a Bayesian average: score = (v·R + 10·C) / (v + 10), where R is the school's rating, v its review count and C = 4.7 the average rating across the directory. A school with a few perfect reviews can't outrank one with hundreds of strong reviews. Schools can't pay to rank higher, and claiming a listing doesn't change its position.

    What are the highest-rated Montessori schools in San Bruno?

    By our ranking, the top 2 are California Montessori School (4.9★, 13 Google reviews) and FSM Montessori School (5.0★, 3 Google reviews). Ratings change, so check each school's page for the current numbers and reviews.

    Ranking methodology: schools are ordered by a Bayesian average — score = (v·R + 10·C) / (v + 10), where R is the school's Google rating, v its review count, and C = 4.7 the review-weighted average rating across the directory. This prevents a school with one 5-star review from outranking consistently well-reviewed schools. When results are otherwise equal, schools with more complete, recently verified profiles come first. This is based on profile quality only; no school can pay for a higher position. Every public school in the directory is ranked; we only list schools that show evidence of a Montessori program.

    Rankings can't be bought. Schools are ordered by Google rating and review count. When results are otherwise equal, schools with more complete, recently verified profiles come first. This is based on profile quality only; no school can pay for a higher position.
