A Dissertation Submitted to Mzumbe University in Partial Fulfillment of the Requirements for the Award of the Degree of Master of Science in Human Resource Management (Msc.HRM) of Mzumbe UniversityThis study examined the factors impeding successful transfer of training; it involved a case study design where Tanzania Fisheries Research Institute (TAFIRI) Dar es Salaam was selected. The study was guided by four research objectives which are: To examine training programmes offered by TAFIRI, to explore how the Training Need analysis is conducted in TAFIRI, to examine to what extent does work environment support transfer of training, and to assess factors impeding successful transfer of training in TAFIRI. The data collection methods comprised interview and questionnaires. Random sampling and purposive sampling techniques were used to select a sample of 27 respondents for the study. Respondents were chosen from ordinary employees, heads of departments and the center director of TAFIRI. The findings indicate that TAFIRI do not offer any training programmes rather the employees support themselves to attend different training programmes to acquire knowledge and skills. Also, they do not conduct Training needs assessment (TNA) to know the need of conducting training programmes but the employees may apply for it and get the permission to attend regardless the need of such knowledge and skills. On the other hand, at TAFIRI there is lack of support and opportunities to perform after the employees attend training programmes. Lastly, there are a lot of factors impeding successful transfer of training at TAFIRI which are categorized into two parts; training characteristics such as absence of motivation, egoism and passive employees; working environment factors such as lack of infrastructure and facilities, poor supervisors and work mates’ support, lack of financial resources and absence of TNA. The study made some recommendations to the Government, TAFIRI management and TAFIRI employees to overcome the factors impeding successful transfer of training.
