The paper describes Project PIPE (Parent Involvement through Parent Education), an approach designed to increase the involvement of parents of preschool developmentally delayed and disabled children in their children's education and treatment programs. Three phases are delineated: (1) development of a community network (facilitating relationships between early intervention programs and community resources agencies); (2) development of a parent resource center containing books, pamphlets, articles, slides, tapes, teaching materials, adaptive equipment or toys and games; and (3) development of a parent centered program (identifying and overcoming barriers to parent participation). A parent-centered curriculum developed by the project is also described. (CL)
