The study was designed to separately examine two cohorts of children, newly entering three- and four-year-olds. This design reflects the hypothesis that different program impacts may be associated with different age of entry into Head Start. Differential impacts were of particular interest in light of a trend of increased enrollment of the three-year-olds in some grantee/delegate agencies presumably due to the growing availability of preschool options for four-year-olds. Consequently, the study included two separate samples: a newly entering three-year-old group (to be studied through two years of Head Start participation i.e., Head Start year and age four year, kindergarten and first grade), and a newly entering four-year-old group (to be studied through one year of Head Start participation, kindergarten and first grade).
Baseline data was collected through parent interviews and child assessments in fall 2002. Data collection included annual spring child assessments, parent interviews, teacher surveys, and teacher-child ratings. In addition, during the preschool years only, data collection included classroom/family day care observations, center director interviews, care provider interviews, and care provider-child ratings. Outcome measures were developed in four domains: child cognitive development, child social-emotional development, health, and parenting practices.
