This report suggests components for a comprehensive statewide inservice training program for personnel involved in implementing the Part H program of Public Law 99-457. These components include: (1) establishment of an inservice program as a requirement for each state participating in Part H; (2) promotion of a statewide comprehensive system of personnel development addressing all disciplines and levels; (3) joint responsibility of the agencies involved; (4) policies focused on training for entry skills and continuing competency; (5) geographically accessible and culturally relevant training; (6) inclusion of private service providers in training; (7) use of the multidisciplinary service model as the unit of training; and (8) focus on case management and collaboration with families. Barriers to inservice training development include limited fiscal and personnel resources for training, previously established policies, crisis orientation as the mode of operation, lack of evidence of effectiveness of inservice training, the poor example of unqualified personnel in existing programs, and professionals' need for identification with their own disciplines. Incentives are needed to encourage states to develop a system of inservice training. The role of the Federal Government should be to provide a model for the states to develop and maintain a comprehensive system of personnel development. (JDD)
