The Family-School Partnership (FSP) Intervention was designed to improve achievement and reduce early aggression and concentration problems by enhancing parent-teacher communication and providing parents’ with effective teaching and child behavior management strategies. The major mechanisms for achieving those aims were (1) training for teachers and other staff members in parent-teacher communication and partnership building, (2) weekly home-school learning and communication activities, and (3) a series of nine workshops for parents led by the first-grade teacher and the school psychologist or social worker. The Parents on Your Side program (Canter & Canter, 1991) was the basis for training teachers in partnership building and parent-teacher communication. The program included a three-day seminar with follow-up supervisory visits and an explicit training manual accompanied by videotape training. The Parents and Children series developed by Webster-Stratton (1984) formed the basis for the parenting workshops center around parent discipline and child behavior management.
