Full Ranking Detail
childcarepreschoolco-op
Diamond Bar Community Preschool is a California Department of Social Services-licensed parent-participation cooperative preschool at 400 S Rancheria Rd in Diamond Bar, serving children ages 3-5 during the school year (September through June). Founded in 1966, it remains a well-established community institution with strong credentials: non-profit status, four credentialed staff members including two teachers, and a 4:1 student-to-teacher ratio. The curriculum emphasizes child-centered learning through daily exposure to art, math, science, language, and dramatic play, balancing self-directed and guided experiences. Parent involvement is central to the model—families commit to assisting in classrooms 2-6 days monthly and serving on committees—which may not suit all working families. The center has limited scope: no infant or toddler care and no summer or full-year programming.
