Sponsored by the US National Institute for Child Health and Human Development (NICHD), these studies focus on child development, child care, and the early school years and include two separate longitudinal panels: ECLS-B, that follows children from nine months of age through first grade, and ECLS-K, which follows through from kindergarten entry to fifth grade.
