Requirements in Public Law 94-142 make it advisable for regular education teachers to become directly involved with special education teachers in designing and delivering appropriate instruction for mildly handicapped students. To facilitate these cooperative endeavors, the National Inservice Network (NIN) has two major components. The first component is on a national scale and links inservice education projects funded by the Bureau for the Education of the Handicapped (BEH). These links increase sharing among projects and identify resources and models that may be useful for other state and local school district efforts. The purpose of the second component is to assist state departments of education in Colorado, Indiana, and Maine in developing resource and dissemination networks for local school districts in developing, implementing, and evaluating inservice training in special education for regular educators. The NIN serves as a linking agency to state departments of education and local school districts in each state. Task forces composed of special and regular educators have been established in school districts and engage in a problem solving and planning process. Comprehensive personnel development plans are based on research on locally identified problems and needs. The NIN assists in the diffusion of model programs and effective practices in special education inservice training. Procedures for improving inservice training are based on assessments or diagnosis of needs and are similar to those in the Individualized Education Programming process: setting achievable goals, formulating and implementing action plans, and evaluating results.
