A Dissertation Submitted in Partial Fulfillment of the Requirements for the Award of the Degree of Master of Science in Human Resource Management of Mzumbe University.The main objective of this study was to find out the contribution of Secondary Education Development Program (SEDP) to teachers’ welfare in Temeke Municipality. The study specifically intended to examine SEDP strategies on improving secondary school teachers’ welfare in Temeke Municipality, to examine the level of SEDP performance in improving teachers’ welfare in Temeke Municipality, to determine factors affecting SEDP performance on improving teachers’ welfare and to explore the implication of teachers’ welfare on quality of secondary education. The study adopted a case study design in which both qualitative and quantitative methods were employed. The study results were based on questionnaire outcomes, interviews and document analysis. The study found that majority of teachers were not aware of SEDP as no preparation were done in acquainting the teachers with enough knowledge and awareness on SEDP, and that SEDP has not been able to improve teachers’ welfare directly as teachers are working in very difficult environment, under very low motivational level and not satisfied with their jobs. The study found that the major factors affecting SEDP performance were poor teachers’ awareness about SEDP, lack of commitment, responsibility and accountability from educational officers and the government as a whole and failure to address teachers’ problems. The study found that teachers are not satisfied with their current welfare status hence they are not committed or motivated in raising the quality of learning in the municipality. The study recommended that education policies should be formulated based on the needs of the society and the advice of the experts, create more awareness on SEDP, teachers grievances should be addressed, increase education budget as well as empowering teachers in any educational interventions.
