This research investigates the influence of intrinsic and extrinsic factors on teachers' work motivation and its impact on educational performance at primary schools. The study addresses the crucial role of teacher motivation in enhancing school education quality. Using a quantitative, descriptive-correlational methodology, the study examined the statistical relationships between intrinsic factors, such as job satisfaction and commitment, and extrinsic factors, such as financial rewards and work environment, on teachers' motivation. Data was gathered from 60 respondents, selected through purposive sampling, and analyzed using multiple linear regression and Pearson correlation. The results revealed that intrinsic factors had a stronger impact on work motivation than extrinsic factors, though both were significant. Teachers who experienced greater job satisfaction and commitment exhibited higher motivation, ultimately leading to better performance in teaching. The study concludes that strategies for improving teacher motivation should prioritize intrinsic factors, while still recognizing the importance of supportive extrinsic elements. This research provides valuable insights into balancing motivational strategies and suggests further exploration in diverse educational contexts to validate the findings.
