A Dissertation Submitted in Partial Fulfillment of the Requirement for the Master Degree of Business Administration in Corporate Management (MBA-CM) of Mzumbe University.The purpose of this study was to determine the impact of Training and Development on public sector organizations using Tanzania Court of Appeal (TCoA) as a case study. The research intended to determine the role and impact of training on employees with emphasis on the lower, middle level staff and the administrators of TCoA, who were randomly selected. The study assessed the training and development process of TCoA and whether training has improved employee performance. A questionnaire was designed using structured questions to collect primary data from employees of TCoA. Personal interviews were held with some head of department’s staff of the organization. The results indicated that TCoA’s employees were not well informed about training and development programmes in the organization. Most of the employees were of the view that training and development were effective tools for both personal and organizational success. The findings revealed that training practices, methods and activities at TCoA are not in line with the best practices regarding the planned and systematic nature of the training process as is generally known. It was recommended among other things, that the processes involved in training be duly followed. Further, TCoA should help its staff identify their career paths and to guide them in the pursuit of higher education.
