This study sought to assess the role of non-monetary incentives on teachers’ job performance in public secondary schools. The study was guided by three objectives; that is, to identify the types of non-financial benefits available to teachers in public secondary schools in Ilemela District, to find out the relationship between non-financial incentives and teachers’ job performance in public secondary schools in Ilemela District and to identify challenges that hinder the provision incentives in the work places of teachers. The study employed mixed research approach and convergent parallel design. The quantitative data were gathered, coded and analyzed through descriptive statistics with the help of SPSS version 20. Qualitative data were analyzed based on themes. The findings revealed that non-monetary incentives seem to play a vital role in improving teachers working performance in public secondary schools. Also, the findings showed that school leaders do not apply non-monetary incentives to their teachers due to inadequate leadership skills. The study recommends that the government in cooperation with the community should build teachers’ houses near the schools in order to make teachers closer to the school activities. The school heads should involve teachers in day-to-day school operations to make teachers part and parcel of the school. Moreover, head of schools should be equipped with administrative skills concerning the improvement of teachers’ job performance.
