摘要：This study aims to develop an instrument to measure elementary school teachers' professional ethics in Indonesia. The instrument was developed from the Yael Fishers' instrument. The instrument's validity in this study was analysed using the Confirmatory Factor Analysis (CFA) method with the M-Plus software. The sample of this study consisted of 437 elementary school teachers in Jakarta, Indonesia. The analysis results show that the teacher professional ethics instrument's factor loading coefficient has a significant t value (t > 1.96). The results also showed a factor model that was fit with Chi-square = 3443.779*, df = 1221, P-value = 0.0000, RMSEA = 0.065, and CFI = 0.908. Based on the results, it can be concluded that the items in the teachers' professional ethics instrument developed can measure defined constructs properly..
