Abstract This paper investigated the impact of work environment on teachers’ productivity in public primary schools in Oshimili South Local Government Area, Delta State, Nigeria. All education systems rely heavily on the quality and productivity of teachers to improve and maintain standards and quality. This survey adopted a descriptive survey. Two research questions and two hypotheses were established for this study. The population of the survey consisted of all teachers and principals of 409 public primary schools in Oshimili South LGA of Delta State. The data collecting instrument was called “Work Environment and Teacher Productivity Questionnaire” (WETPQ) The survey questions were answered using the mean and standard deviation, a benchmark score of 2.50 was considered acceptable. Conversely, the hypotheses were tested using a z-test with an alpha level of 0.05. The results show that the availability of adequate lighting and space has a significant impact on the productivity of primary school teachers. Based on the results, it was recommended that classrooms and offices should be properly lit, classrooms should be large enough to support effective and efficient teaching and learning, and policy makers should improve working conditions for primary school teachers.
