The professional internship exchange program was designed to provide in-service vocational personnel development in cooperative vocational education. Ten new centers were established under this project. A total of 30 secondary high schools and community colleges throughout the State of Washington have participated in the three-year project. Approximately 500 youths and adults in cooperative programs along with persons with special needs have been served. Micro-teaching devices and micro-simulated decision making were emphasized throughout the planning workshop. This publication includes complete individual center (school or community college) evaluations from 1970-73. Through this program teacher coordinators and business/industrial representatives have developed a better understanding of the complex nature of the interaction work and education. Teacher coordinators have kept abreast of job changes, task analysis, and those areas of occupations which will provide employment for the future. (EA)
