Educational reform in the modern era which the school administrators and all personnel in the school Must improve and develop themselves to keep up with changes in the era of globalization. By using the supervisory management model process to develop educational quality, these research objectives are to: 1) Study the problems and elements of supervision. Target group: 15 people 2) Create a supervisory model. By conducting in-depth interviews with 15 people involved. 3) Experiment with the supervision model with a sample group of 3 schools. 4) Evaluate the use of the supervision model. By organizing a seminar with 15 experts and asking for opinions about its usefulness. Feasibility, appropriateness, and correctness of the format from 291 study supervisors. The instrument used was a questionnaire. Statistics were used to find the mean and standard deviation. It can be summarized as follows: 1) Problems in supervision include an insufficient number of supervisors. Study supervisors lack knowledge Lack of good supervision skills and no systematic planning. There are 5 important elements as follows: (1) objectives, (2) planning, (3) supervision, (4) monitoring and reflection, and (5) development and application. 2) Creating a model for supervision, including (1) objectives, (2) content of supervision, (3) process, (4) method, (5) supervisor and supervisor, (6) duration, (7) planning, (8) execution, (9) Evaluation, (10) teamwork, (11) network building, (12) knowledge management, (13) learning and quality development, (14) building morale, and (15) improving development. 3) The results of the trial use of the model had a reliability value of 0.80. Average comparison results in Knowledge before training and after training, tested with a t-test, and were found to be different. Statistically significant is at the 0.01 level. They were satisfied with the model. Overall, it is at the highest level ([x-bar] = 4.90, S.D. = 0.53) and the results of the overall evaluation of the use of the format are at the highest level ([x-bar] = 4.89) and overall satisfaction with the use of the format is at the highest level ([x-bar] = 4.63). 4) Model evaluation results are useful feasibility, suitability, and correctness. Overall, it is at the highest level ([x-bar] = 4.63, S.D. = 0.12).
