This project will conduct a randomized clinical trial (RCT) in five Educare Schools to examine the effectiveness of a model early education program for children from low-income families. The Educare model of early childhood education is high-quality, center-based Early Head Start/Head Start programming for children from birth to age 5 in high-risk communities. The core features of Educare include well-educated and supported teachers; a focus on children's social-emotional development as well as language, literacy, and cognition; extensive family involvement opportunities and support; and a reliance on evidence-based practices. The Educare RCT will include longitudinal follow-up of 239 infants and their families through age 3. Measures will include annual child developmental assessments, videotaped parent-child interaction observations, and parent interviews and surveys.
