Why this rating
This daycare earned 4 out of 5 stars overall. Heads-up: this facility's license is currently under sanction or carries an open enforcement action. Process quality reflects a Parent Aware rating of Level 4 (out of 4). Structural quality reflects a license currently under sanction (probation or restriction). The structural rating also includes Minnesota's licensing baseline — what every licensed daycare in the state must meet. Minnesota caps infant ratios at 1:4, toddler ratios at 1:7, and preschool ratios at 1:10. Lead teachers must hold a Child Development Associate (CDA). Teachers must complete 24 hours of annual training.
