Early Childhood Longitudinal Studies (ECLS)

Project

The Early Childhood Longitudinal Studies (ECLS) program offers the first nationally representative study of early childhood development and education in the United States. The ECLS program currently has three separate longitudinal studies fielded by the National Center for Education Statistics (NCES): The Early Childhood Longitudinal Study, Kindergarten Class of 1998–99 (ECLS-K); the Early Childhood Longitudinal Study, Birth Cohort (ECLS-B); the Early Childhood Longitudinal Study of 2010–11 (ECLS-K:2011). These studies are intended to complement one another; together, they provide a picture of children’s development and education from birth through the elementary and middle school years.

Since the base year of the first ECLS study, the ECLS-K, AIR has provided support for study design; instrument development; assessment development; field testing; main study collection; database and database documentation development; and training of researchers on the various ECLS databases.
