This study developed an Electronic Evaluation System (E-ES) for students' teaching evaluation in Vocational and Technical Schools (VTS). The E-ES model consisted of an application program and an instrument of students' teaching evaluation. This study employed the Analyse Design Develop Implement and Evaluate (ADDIE) model. The implementation of the E-ES model was carried out in 12 VTSs, with the sample of 312 students and 32 teachers selected randomly. The data were collected through questionnaires and interviews and analyzed by using descriptive statistics and t-test. The data collection was conducted twice, at the end of the sixth week and the twelfth week of the odd semester. The results of the study showed that (1) the E-ES application program was successfully developed and was considered feasible at a moderately high degree and; (2) the teaching evaluation instrument was valid (V-Aiken Coefficient Index=0.78), and its reliability with Alfa Cronbach was α=0.74; (3) the usability of the model was in a moderately high degree; (4) the students' satisfaction with E-ES was classified into the a moderately high degree, and the teachers' satisfaction of the E-ES was in a moderately high; (5) There was an increase of the teaching quality after the E-ES implementation .
