The Early Childhood Longitudinal Study (ECLS) program includes four longitudinal studies that examine child development, school readiness, and early school experiences from birth through elementary school. The program provides data to analyze the relationships among a wide range of family, school, community, and individual factors with children's development, early learning, and performance in school. The birth cohort of the ECLS-B is a sample of children born in 2001 followed from birth through kindergarten entry. The kindergarten class of 1998-99 cohort is a sample of children followed from kindergarten through the eighth grade. The kindergarten class of 2010-11 cohort is a sample of children followed from kindergarten through the fifth grade. The newest ECLS program study, the ECLS-K:2024, will follow the kindergarten class of 2023-24 through the fifth grade.

The National Household Education Surveys Program (NHES) is a household-based data collection system designed to address a wide range of education related issues. The NHES collects timely data about the educational activities of the U.S. population. NHES surveys have been conducted every two to four years since 1991. Recent NHES data collections consist of two surveys: The Early Childhood Program Participation survey and the Parent and Family Involvement in Education survey. Most NHES surveys have been conducted on a repeating basis to measure the same phenomena at different points in time. The NHES has included surveys on adult education, parent and family involvement in education, before- and after-school programs and activities, civic involvement, early childhood program participation, household library use, school readiness, and school safety and discipline.
