Why this rating
This daycare earned 4 out of 5 stars overall. Structural quality reflects a 31% violation rate and a license in good standing. The structural rating also includes California's licensing baseline — what every licensed daycare in the state must meet. California caps infant ratios at 1:4, toddler ratios at 1:6, and preschool ratios at 1:12. Lead teachers must hold a High School Diploma. Annual training isn't required by the state. No objective process measures (e.g., state quality rating or national accreditation) are available for this daycare. The overall rating reflects structural features only.
