Pacific Rim International School is a dual-accredited Montessori center at 2600 Campus Dr in San Mateo, serving infants through high school with rare full-age continuity via Mandarin, Japanese, or Spanish immersion. The facility holds active CCLD license #414004813 (most recent inspection September 2025), AMI accreditation, and International Baccalaureate Organization certification—a rare combination that reflects its international-education focus. Parents consistently praise its tranquil campus, faculty warmth, and self-directed learning model; with 35 Yelp reviews and a 4.5/5 Niche rating, it demonstrates strong community satisfaction. The center's 120-seat capacity and 9:1 student-teacher ratio support meaningful individualized attention across its six age-based programs and extended offerings. A pair of Type B citations in recent CCLD inspections merits review of compliance history, and tuition exceeding $44,000 annually for upper grades ranks among San Mateo's most expensive programs, with financial-aid availability unclear.
