The Early Childhood Longitudinal Study (ECLS) program includes two longitudinal studies that examine child development, school readiness, and early school experiences. The birth cohort (ECLS-B) is a sample of children born in 2001 and followed from birth through kindergarten entry. The kindergarten cohort class of 1998-1999 (ECLS-K) is a sample of children followed from kindergarten through the eighth grade.
