Centennial Montessori School is an AMI-accredited, CCLD-licensed center-based provider at 27 Tenth Ave in San Mateo, serving children from 18 months through grade 4 using the Montessori approach. The school's three age-based programs—Young Children's Community, Children's House, and Elementary—emphasize observation-based instruction and foster lasting peer relationships across multi-year enrollment. Parents praise the community as "family-like" with strong academic and emotional outcomes (GreatSchools 5.0/5), and the school's unusual Parenting Center program strengthens home-school alignment. Capacity is 60, and the inspection record is clean with a single minor citation since 2006. Hours are 8:00am–3:30pm, and tuition reaches approximately $31,750/year for upper grades—factors that may require supplemental aftercare and limit access for some families.
