As the saying goes ‘education is the key to success’. When the majority of a nation’s citizens are educated, development becomes rapid. This research aims to determine the influence of a principal’s leadership, teacher competencies, academic supervisor, work motivation and job satisfaction on teachers' performance. This study employed the quantitative approach. The survey method was used to collect information through a questionnaire with a Likert-type of 5 rating scales to analyze data. A total number of 125 respondents were involved in the study and they were randomly selected from the secondary schools in Regional Education Directorate I&II. Data were analyzed using multiple linear regression and the coefficient of determination test R^2. The results show that the principal's leadership, teacher competencies, academic supervisor, and job satisfaction have a positive and significant influence on teachers’ performance, while work motivation has no significant influence on teachers’ performance. To have effective teaching and learning in schools, good leadership is required to guide, manage and control people, property and issues affecting them with proper handling to achieve the set goals. The Principal's work can be complemented by the efforts of his vice principals and other senior teachers as supervisors to ensure that plans are properly implemented and objectives achieved.

These activities may lead to good working conditions and a conducive environment for the staff to be motivated and satisfied with their job.
