This article presents a longitudinal analysis of the Florida Parent Education Programs which were designed to provide intervention services to socioeconomically disadvantaged parents of young children through home visits by paraprofessional personnel. The programs include the: (1) Parent Education Project (PEP); (2) Early Child Stimulation through Parent Education Project; (3) Home Learning Center Project; (4) Instructional Strategies in Infant Stimulation Project; and (5) Project Follow Through. Data were collected from children, ages 1-6, who had entered the programs since 1966 and had participated from one to three years. Skills and attitudes of the mothers were also assessed. Descriptions of the projects' effects on the participants are given. The measurement design included experimental and control groups, assessed by standardized tests, interviews and Parent Educator Weekly Report Forms. The results indicate that the parent education approach has had lasting effects on the children and on some aspects of family life. (SDH)
