Early Childhood Longitudinal Program

This federally funded program is made up on three longitudinal studies that examine child development, school readiness, and early school experiences. The birth cohort of the ECLS-B is a sample of children born in 2001 and followed from birth through kindergarten entry. The kindergarten class of 1998-99 is a sample of children followed from kindergarten through the eighth grade. The kindergarten class of 2010-11 cohort will follow a sample of children from kindergarten through the fifth grade.

It is important for reporters to know about these studies because researchers have used the data to investigate a variety of questions around the early years of schooling.
