The Evaluation and Training Institute (ETI) is conducting a three-year evaluation of the High-Quality School Readiness Expansion (HQSR-E) program to determine how participation in high-quality preschool programs impact children’s school readiness. In 2017-2018, the second year of the evaluation, we focused on answering the following three overarching research questions: 1. Did high-quality preschool children have better early literacy skills at entry to kindergarten compared to children who were not enrolled in a high-quality preschool program? 2. Did high-quality preschool children have better early math skills at entry to kindergarten compared to children who were not enrolled in a high-quality preschool program? 3. What were the social-emotional development skills of program children at the conclusion of the preschool year? (author abstract)
