Education serves as the cornerstone of national development, yet achieving quality education requires more than just infrastructure and policies; it demands a conducive organizational environment and a dedicated teaching force. In the Philippines, schools often grapple with challenges such as limited resources and large class sizes, making it imperative to understand how management and teacher attitudes influence success. This study aimed to determine the mediation role of collective teachers’ efficacy, motivation, and commitment on the relationship between the school organizational environment and school performance among schools under the Nagcarlan Sub-Office.

The study involved 203 respondents. They were selected through purposive sampling. The study utilized mediation analysis. The respondents were predominantly female teachers who are experienced and hold master’s degrees. Results revealed that the school organizational environment is generally positive, characterized by strong transformational and instructional leadership, adequate resources, and accessible professional development. Consequently, teachers demonstrated high levels of collective efficacy, motivation, and commitment, leading to a perceived “Very Good” level of school performance across all dimensions.

Statistical analyses confirmed significant positive relationships among the variables. The organizational environment significantly influenced both teacher characteristics and school performance, with leadership and professional development showing the strongest impact. Furthermore, mediation analysis established that collective efficacy, motivation, and commitment function as significant partial mediators. This implies that while a supportive environment directly improves performance, it also indirectly enhances educational outcomes by fostering teachers’ confidence, drive, and dedication.

The study concludes that improving school performance is not merely about facilities, but about creating an atmosphere that strengthens the professional attributes of teachers.
