Early Childhood Longitudinal Study: Birth Cohort, 2001-2002, Preschool Data [United States] (ICPSR 28082)

Principal Investigator(s): United States Department of Education. Institute of Education Sciences. National Center for Education Statistics


The Early Childhood Longitudinal Study (ECLS)is designed to provide decision makers, researchers, child care providers, teachers, and parents with detailed information about children's early life experiences. The birth cohort of the Early Childhood Longitudinal Study (ECLS-B) looks at children's health, development, care, and education during the formative years from birth through first grade. This third wave of the data was collected when the cohort was preschool aged. For the preschool collection, the ECLS-B child assessment protocol was modified to take into account the study children's growing competencies and to focus more on indicators of school readiness. The BSF-R was replaced with an early reading and mathematics assessment similar to the assessments used in the Early Childhood Longitudinal Study, Kindergarten Class of 1998-99 (ECLS-K) kindergarten and first grade collections. Unique to the preschool wave was the assessment of children's knowledge of basic colors. Fine motor skills were assessed by asking children to copy a series of forms/shapes drawn by assessors and to build structures using blocks. Gross motor skills were assessed by asking children to jump, balance on one foot, hop on one foot, skip, walk backward along a line, and catch a bean bag. Additionally, as in the previous waves, children's social interactions with the parent respondent were assessed using the Two Bags Task. All children had their height, weight, and middle-upper arm circumference (MUAC) measured, and children born with very low birth weight had their head circumference measured.
