Results of an interim evaluation of selected aspects of the Follow Through Program are described. Analyses are described for two cohorts: children entering the program in 1969 (2 year's data) and those entering in 1970 (1 year's data). Measures on program impact on the children included achievement, quantitative skill, language arts, cognitive processes, affect, and attendance. Various measures of program impact on the parents were also taken. Overall interim results, for the most part, favor the Follow Through children. Caution is advised in interpreting results of this interim evaluation. (CS)
