The evaluation of experimental teacher professional development has been taken since 2006. However, only few researches of effectiveness of this program were conducted. Furthermore, most of these researches equalized effectiveness with results and not on the effectiveness of the practice process. This study aims to examine the effectiveness of teacher professional development evaluation and the program by analyzing the opinions of 21,442 teachers and parents in 1,028 elementary schools, junior high schools, senior high schools and vocational schools. A internet questionnaire has been sent to 21,442 teachers and parents, of which a total of 6316 questionnaires from teachers (29.46%) are valid, while 747 questionnaires from parents (36.4%) are valid. Followings are conclusions: 1. A high level of acceptance of the implementation of teacher professional development evaluation, contrast to a low willingness to participate among teachers. 2. More acceptance of the effectiveness in the practice process of teachers than the effectiveness seen in the results. 3. Main factors behind the low participation of teachers in the program were their work load, doubt of evaluation and implementation, over-emphasis on documents, a certain lack of appropriate rewards and encouragements and the insufficient supports and resources. 4. A need for a simplification of the process and paperwork of evaluation, and a good system of benchmark andreward. 5. More acceptance of the implementation of teacher evaluation from parents than from teachers.
