The ComField model of the Northwest Regional Educational Laboratory requires that trainees demonstrate, prior to certification, their ability to bring about learning outcomes in children and parental involvement in the program. Hence, the functions and behaviors of teachers in given settings need to be specified. The ComField model itself does not specify them; rather the adopting college and public school system should be equal partners in selecting the competencies and behaviors to be taught in laboratory and live conditions. Similarly, they should jointly evaluate trainee performance and make policy decisions. The model also expects the trainee to become a self-understanding, self-directed learner, to contribute to the design and continual assessment of the program, and to function in a wide range of social contexts. The latter presumes the involvement of the community. The model provides for a preservice component, which can be adapted to many types of education programs, and an inservice component for supervising and practicing teachers. It also features eight support systems: personnel, supplies, instructional development, program evaluation, program modification, cost accounting, and a computer-based information management system.
