Georgia's Pre-K, administered by Bright from the Start: Georgia Department of Early Care and Learning (DECAL), aims to provide four-year-olds with high-quality preschool experiences to help prepare them for kindergarten. A recent evaluation of Georgia's Pre-K indicated that participation in the program had significant positive effects on children's skills at the start of kindergarten. However, no recent study has examined outcomes at later grades for Georgia's Pre-K children, compared with children who did not participate. The current study aimed to fill that gap by comparing third-grade scores on the Georgia Milestones End-of-Grade (EOG) tests for children who had and had not taken part in Georgia's Pre-K.
