Photo: Montessori Achievement Centre · GoogleSpring Valley, California has 2 Montessori schools in our directory as of November 2026; 1 of them have Google reviews. We only list schools that show evidence of a Montessori program.
Only 1 school of 2 here publishes tuition, so we don't show a range for Spring Valley; 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.
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.
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.
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.
By our ranking, the top school is Montessori Achievement Centre (4.0★, 4 Google reviews). Ratings change, so check each school's page for the current numbers and reviews.

Add your schoolRanking 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.
