View Sunnyside Montessori House of Children full profile →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 of all verified Montessori schools on MontessoriCity. This prevents a school with one 5-star review from outranking consistently well-reviewed schools. Only schools verified as authentic Montessori programs are ranked.
