Described is the Program in Early Childhood Development (PECD), a school-community project initially funded under Title III to provide identification, diagnostic, and intervention services for 3-to 5-year-old children in Evanston, Illinois prior to kindergarten entry. Two major sections deal with screening procedures (in such areas as social-emotional development, gross and fine motor perception, and cognition) and formal and informal diagnosis (in such areas as vision, hearing, speech, and language). Depending on the child's needs, it is explained that the program's intervention phase can consist of three alternatives: recommendations for remedial activities to be implemented by parents or preschool teachers; referral to a community agency for treatment; or enrollment in individual, small group, or multidisciplinary group therapy. A final section briefly covers information dissemination to kindergarten teachers and special services personnel. Sample history and evaluation forms are included in the screening section and in the appendixes. (LH)
