Reported are findings on the effectiveness of the Family Education Program (FEP) of the Early Childhood Intervention Project, a program of the Social and School Adjustment Research Group of the University of Quebec in Montreal. In general, the findings suggest that, under certain conditions, it is possible to get parents to participate in an educational intervention with their preschool children. The first half of the paper establishes the rationale for the FEP and outlines, by way of illustration, the content of the first 2 of 12 FEP sessions. All sessions require active participation of parents, and consist of discussion, training, and knowledge acquisition periods. These periods mainly concern children's behavior, language, psychomotor abilities, reasoning, and emotional expression. The remainder of the report focuses on program evaluation findings about (1) the frequency of parent participation at sessions; (2) the degree of parent satisfaction; and (3) change in parents' attitudes and educational practices.
