Containing content and materials for 14 workshops, this training guide has been developed to assist Head Start programs in developing and implementing individual service plans (ISPs) for high-risk preschool children. Differing from the public schools' individual education programs, the ISP addresses all educational needs of the child as well as needs in other component areas, such as health, nutrition, parent involvement, and social services. The first four workshop topics cover screening, diagnosis, educational assessment, and component assessment procedures. Development of the ISP is subsequently covered in workshop material concerned with (1) writing a rationale for the ISP; (2) conducting ISP conferences and related home visits; (3) writing statements of the child's current level of functioning; (4) establishing long term goals for each area of development; (5) writing short term objectives and instructional objectives in behavioral terms; and (6) completing ISP sections having to do with special services, materials, person(s) responsible, evaluation criteria, and time lines. ISP implementation is covered in workshop material focusing on analyzing tasks, writing activity charts, and planning the classroom environment and schedule. The final workshop focuses on "transitioning" (i.e., helping handicapped children make the transition into the public school system). Six appendices provide references, excerpts from related books, guides to screening and assessment activities, and directions for developing ISP packets and videotapes. An ISP for use in training activities is included in the last appendix. Forms useful for developing ISPs are provided throughout the training guide. (RH)
