Produced by an urban school district, this manual provides guidelines for developing and implementing a preschool screening and follow-up program that is based on community involvement. Part 1 of the manual presents a rationale for preschool screening and outlines the major components of a screening program. Also included in part 1 is a discussion of the prescreening, screening, and postscreening activities included in the implementation of a community-based preschool screening project. Part 2 outlines a volunteer training program for technical and nontechnical components of the screening project. Discussion concerns nontechnical assistance, and screening for development, vision, medical and health condition, and communicative abilities. The rationale for this section is that many communities could not afford to offer preschool screening services without the assistance of trained volunteers. Part 3 addresses the need for staff in-service and offers suggestions concerning content and format of an early identification workshop for teachers. The purposes of the proposed workshop are to create awareness of the importance of early identification of children with special needs and to present ways in which teachers can play a critical role in the screening and follow-up process.
