Summary View help for Summary
The Early Childhood Longitudinal Study (CLS) 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 first wave of the data was collected when study children were approximately nine months of age. Children's cognitive and motor skills were assessed using a modified version of the Bayley Scales of Infant Development (BSID-II), called the Bayley Short Form-Research Edition (BSF-R). Children's socioemotional development was assessed through a taped interaction with their primary caregiver (i.e., the parent respondent) using the Nursing Child Assessment Teaching Scale (NCATS). All children had their length (i.e., height), weight, and middle-upper arm circumference (MUAC) measured. Additionally, children born with very low birth weight had their head circumference measured.
