Abstract--Teacher development is one of the main tasks of school supervisors. In practice, teacher training has not been implemented optimally. One of the causes is the untapped use of media in supporting the implementation of teacher development. The purpose of research and development is to develop teacher development model. The method used is research and development. Implementation of teacher coaching model begins with programming. Furthermore, the supervisor gives a schedule whenever he will carry out teacher training. School supervisors in carrying out guidance of teachers performed consistently, especially in providing guidance through programmed coaching. Data obtained through observation, interviews, and tests. Data were analyzed descriptively qualitative and quantitative. The results showed that: (1) the model of teacher development by the school supervisors developed was tested feasible and effective; (2) the model has also been tested to have a high degree of stability; (3) the model of teacher training by school supervisors has an impact on improving the professional ability of teachers; (4) teacher development model can support the implementation of task of school supervisor especially in conducting programmed teacher development; (5) the developed model can support the implementation of school supervisor's duties in conducting teacher training.
