The design of this Planned Variation study examines the impact of Project Follow Through on children, focusing on the 1-year kindergarten experiences of the third Follow Through group. Chapter 1 presents a short history of Follow Through and a description of each of the participating program sponsors. Chapter 2 considers the problems faced in constructing a manageable set of questions which could be put to the available data. Chapter 3 describes the subject of sites and children utilized in the analyses. Chapter 4 describes the covariables used in making the adjustments for initial differences between groups being compared. Chapter 5 presents the statistical strategy chosen for these analyses, the methods of presenting results, and the manner of interpreting the tabulated results. Chapter 6 represents a pause in the flow of the evaluation report to provide the reader with some contextual information necessary for sensing the meaning behind some of the numbers reported. Chapter 7 presents the major comparisons between the Project Follow Through and the non-Follow Through schools across all programs, and by each program. Chapter 8 presents a series of studies which suggests some interesting educational implications, while chapter 9 considers the problem of comparing the several programs on the outcome measures. (CS)
