The Massachusetts Special Education Manpower Planning Project is described. Relying on cooperative planning, the project developed a system to provide information on manpower planning, a system to link other agencies with the project, and annual statements of state special education training priorities. The project also collaborated with six other northeastern states. An introductory section describes the project's background and provides an overview of its components. Part II presents performance data on six objectives: manpower information system: coordination, communication, and resource sharing; comprehensive planning for special education; use of evaluation results to improve the project; cooperation with other manpower projects; and work with interstate manpower planning. Part III discusses problem areas and successes for the project's manpower information system, participatory planning system, technical assistance system, training priorities, and management and support. More than half of the document consists of 19 appendices, including data collection forms and personnel data summaries, project evaluation results, and project technical assistance summaries. (CL)
