Technical Assistance for Mainstreaming Exceptional Children (Project TAMEC) assists regular education personnel in working with the mildly handicapped children in their schools. An extension of this North Carolina-based project is an onsite administrator inservice program--the Three Phase Program for School Administrators. Organizational development is the focus of the program with the philosophy that the school principal needs to fill the role of change agent if quality services for the handicapped are to be offered with a high degree of consistency at the local school level. A chronology of the activities during the 3-year project period (1980-83) demonstrates the effectiveness of the research and development cycle to develop an individualized approach to inservice preparation. A bibliography with nine citations is appended. (MLF)
