The National Institute for Early Education Research (NIEER) conducted a landscape evaluation of early childhood programs in Indiana (IN) between the spring of 2021 and the summer of 2022. The evaluation included assessments of infant, toddler, and preschooler children’s developmental status in multiple domains at two time points to measure growth. Commissioned by Early Learning Indiana (ELI), with generous support from Lilly Endowment Inc., this study aims to provide Indiana programs and policymakers with research-based information on the quality of early childhood programs, as well as the learning and development status of young children birth to five in the state. This study employed a set of standardized child assessments designed to measure learning across various domains that are psychometrically valid, proven to discriminate effects in intervention studies, and appropriate for the age range of birth to five.
