To increase parent involvement and meet the need for adult help in classrooms, a preschool director implemented a practicum in a church-owned, nondenominational preschool serving 250 children from an upper-middle-class community in the Northeast. The intervention offered a wide range of parent involvement activities, including the formation of a Parent Association and the recruiting, orienting, training, and evaluating of parent classroom assistants. A four-session training program for classroom volunteers covered school policies and procedures, classroom procedures and management, child development and curriculum, positive reinforcement and behavior management, and work attitudes and confidentiality. This program was followed by hands-on training in the classroom. Practicum evaluation data indicated that the program was successful in increasing parent participation. Twenty-one appendices contain related materials. (RH)
