2. Presentation Overview • Describe the goals and design of the ECLS-B • Identify special features of the design • Describe data released to date

3. Purpose of the ECLS-B • Measure child cognitive, physical, and socioemotional development from infancy to kindergarten entry • Measure the ways in which home learning environments and early care and education providers support that development

4. ECLS Conceptual Model Family School Early Care and Education Child Neighborhood and Community

5. Sample Design • Nationally representative sample of children born in 2001. • sampling frame drawn from U.S. birth certificates. • Oversamples of special populations • low birth weight – American Indian/Native Alaskan • very low birth weight – Asian/Pacific Islander • twins – Chinese* • n 14,000. • * The separate oversample of Chinese infants permits precision in statistical comparisons of Asian/Pacific Islander infants with members of their largest ethnic subgroup.

6. Study Design • Data are collected at multiple points in time. • Data are collected from multiple sources. • children – teachers • mothers and fathers – schools • child care providers • Data are collected through multiple methods.
