This paper is the result of an empirical study that was conducted to assess the effectiveness of the mechanisms used for monitoring and evaluating staff training and development programmes at the university libraries in Ghana. The study was necessitated by the need to scientifically assess the methods/mechanisms put in place for monitoring and evaluating staff training and development programmes at the university libraries in Ghana in order to make recommendations that will enable the libraries maximised the benefits of training.The study used the mixed methods research approach, thus a combination of quantitative and qualitative approaches. The mixed methods were applied in data collection analysis and interpretation of the findings of the study. The study also adopted the survey... research method.The findings reveal that even though the majority of the institutions conducted training needs analysis/assessment for library staff, the process was not properly done. The results also indicate that multiple methods were used in identifying the training needs of the library staff of the university libraries in Ghana.The findings further reveal that not all the institutions followed the Kirkpatrick model or any known training model of monitoring and evaluating reaction, learning, behavior,results and return on investment in training.The study recommends that, monitoring and evaluation should be done by all the stakeholders namely, trainers, trainees, supervisors, co-workers and managers and the feedback of the evaluation should be shared with the stakeholders to help improve upon future staff training and evaluation programmes.
