A strong performance is depicted by the way teachers perform their professional roles and functions. Hence, this research used a quantitative approach to examine various variables affecting teacher performance, including multicultural leadership and the role played by the school board, as dependent variables. At the same time, organizational climate acted as an intervening variable. The sample population involving 170 teachers and 30 school principals was drawn from State Senior High School in Tangerang District, Banten Province. Additionally, the research utilized two units of analysis; teachers and principals. Where the two units of analysis assess each research variable, namely multicultural leadership, the role of the school board, organizational climate and teacher performance. Quantitative data analysis was performed using variant-based Structural Equation Modeling (SEM), with Partial Least Square (PLS) or PLS-SEM. The results indicated that direct and indirect variables impact the performance of teachers. Also, the results revealed that teachers and principals have two opposing perspectives.
