One of a series designed to help Florida school districts provide special programs for exceptional children, the manual presents a training guide on interagency coordination for profoundly mentally handicapped students. Instructions are provided for conducting group sessions and extensive examples of handouts are furnished. Objectives are listed and procedures detailed for each of four modules covering the following topics (sample subtopics in parentheses): participation in service planning (use of different terms to refer to the target population, organization of state and local education agencies, need for joint planning and service delivery); statutes, rules, and regulations affecting service planning (state and federal requirements for sevice plans and reviews, legal terms); documents used for service planning (planning processes for Individual Educational Programs and habilitation plans, relationships among different service plans); and methods for cooperative planning (alternative methods of cooperative planning, their advantages and disadvantages). Each module also includes questions to ask, aspects to explain, and self-check exercises. (CL)
