Abstract: The aim of this study was to establish the role of training duration in the performance of non-teaching employees in public universities in Kenya. The study was conducted in eight of the twenty-two public universities in Kenya with a sample size of 176 non-teaching employees. The study was both qualitative and quantitative. Qualitative due to descriptive statistics which were used in interpreting data and quantitative due to data obtained from questionnaires that was interpreted using statistical packages like SPSS V 20, and Stata V 12, and analysis was done by regression and correlation. The study used open and closed ended questionnaires and a Likert measurement scale of 1 to 5. The study results revealed that Training Duration (p value = 0.001) was statistically significant and therefore had a role to play in the performance of the non-academic staff at the public universities.
