Organizational culture and principal leadership practices play important roles in promoting teachers’ commitment and job satisfaction. This study identified the schools’ organizational culture and the principals’ leadership practices in relation to the teachers’ level of job satisfaction in the Division of Zamboanga del Norte during the school year 2019-2020. The researcher used a descriptive-correlational design in the study. Fifty-four school heads and 233 teachers were chosen as respondents through stratified sampling. The researcher used the modified and adapted Organizational Culture Assessment Inventory, Leadership Practices Inventory, and Teacher Job Satisfaction Survey Questionnaire as the instruments. The Mean, Standard Deviation, Pearson Product Moment Correlation Coefficient, and Stepwise Multiple Regression Analysis were used to analyze and interpret the data.

The schools’ organizational culture regarding dominant characteristics was related to the teachers’ job satisfaction in supervision, colleague, working condition, pay factor, and security. The organizational leadership was related to the teachers’ security. Organizational glue was related to the teachers’ satisfaction with their working conditions and pay. The schools’ strategic emphasis were also related to the teachers’ satisfaction level on the pay factor. Criteria of success of the organization were related to the satisfaction level of teachers in the areas of a colleague and pay factor. The principal's leadership practices in modeling the way were related to the teachers’ job satisfaction regarding pay. The school’s culture in the areas of dominant characteristics and organizational leadership; and the principals’ leadership practices on encouraging the heart of the teachers were the predictors of teachers’ job satisfaction. The school has a very effective organizational culture and leadership practices of principals.
