Teacher performance is a fundamental element in the learning process, this study aims to analyse the influence of exogenous on endogenous variables, with work confidence being an intermediate variable. This study used path analysis as a research design; the total research participants are 360 high school teachers; data validation was carried out using Rasch analysis software model with Winteps version 4.4.7 to obtain standardised research instruments. Data validation was carried out with Smart-Partial Least Square version 3, stating that all data at R > 0.70 are valid and have high reliability. The results of the analysis show a positive influence of leadership style and work environment on trust, leadership style, work environment and confidence in the performance of teachers. In addition, there is also an indirect influence of leadership style on the teacher's performance by faith and the work environment on the teacher's performance by trust. In addition, data analysis generates trust as an intervention variable that effectively affects teacher performance. The results of the research require a follow-up of how the working environment can be improved to improve the quality of education at the macro level.
