Why this rating
This daycare earned 5 out of 5 stars overall. Structural quality reflects a license in good standing. The structural rating also includes Illinois's licensing baseline — what every licensed daycare in the state must meet. Illinois caps infant ratios at 1:4, toddler ratios at 1:5, and preschool ratios at 1:10. Lead teachers must hold a Child Development Associate (CDA). Teachers must complete 15 hours of annual training. No objective process measures (e.g., state quality rating or national accreditation) are available for this daycare. The overall rating reflects structural features only.
