The results of the secondary analysis of data obtained in a study of Head Start graduates in the public schools are summarized in this report. Due to unforseen circumstances, the original longitudinal research design was not fully implemented, and the study was constrained to one administration of a test battery to first-grade students. The primary analyses of that data are reported in "A National Survey of Head Start Graduates and Their Peers" (ED 152 422-423); it is recommended that both the original study and the secondary analysis be read sequentially for a coherent picture of the full study. Questions addressed in the secondary analysis focus on (1) Head Start curriculum emphasis, (2) ethnic composition of families served by Head Start, (3) ethnic composition of staff participating in Head Start, (4) Head Start Center sponsoring organizations, (5) parent involvement in Head Start, (6) preschool experiences of children who did not attend Head Start, (7) performance of Head Start children in public schools, (8) teacher perceptions of Head Start children, (9) interrelationships among predictors of child outcomes, (10) characteristics of high-income Head Start families, (11) parent characteristics associated with parent involvement, and (12) length of enrollment as a factor in child outcomes. In conclusion, main results of the transitional study are summarized. (Author/RH)
