Abstract: This study sought to understand and explain the effect of Motivation and Job Satisfaction on the teachers of Mentari School Bintaro (MSB). Sampling method used was purposive sampling, using 97 teachers as samples out of a population of 129. The use of 97 samples was the researcher’s justification based on the fulfillment of respondent response requirements for the eligibility of questionnaire data to be processed further. Eligible questionnaire data shall have corresponding response for each statement proposed and it shall not be outlier. Data collection method used was in the form of questionnaires, using Likert scale. Validity and reliability testing included the Pearson product moment and statistic Cronbach’s Alpha tests. Analytical method used to answer the hypotheses was multiple linear regressions. The results of the study showed that motivation and job satisfaction simultaneously had significant and positive effect on performance. In partial, motivation had significant and positive effect on the performance of the teachers. Likewise, job satisfaction also had significant and positive effect on the teachers’ performance. The highest correlation was between the dimension of extrinsic motivation found in motivation variable and the dimension of learning evaluation in performance variable. Improving teacher’s motivation by involving them in the school’s decision making, coupled with the school’s management support is expected to improve the teachers’ productivity, thus enabling the school to achieve its goals.
