    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.
