Early Childhood Longitudinal Study (ECLS)
The Early Childhood Longitudinal Study (ECLS) is a research project by the U.S. Department of Education that tracks children from pre-kindergarten through elementary school. It collects detailed information about children's development, learning, and educational experiences over time. The goal is to understand how early childhood experiences influence academic achievement, social skills, and overall well-being, helping educators, policymakers, and researchers improve programs and policies to support children's success.
