The R&P D, responsible for conducting research and policy analysis of Nepal Police (NP), identified the current research as a major research area that had direct impact on human resource development of NP. Therefore, the research was conducted in order to provide key recommendations for the improvement of the course design and effectiveness. The Post Graduate Diploma in Police Science (PGDPS) course was initiated in January 2005 as a part of professional development of freshly recruited Inspectors, and in-service?Inspectors, of NP. The main objectives of the research was to identify the effectiveness of PGDPS by assessing the competency and commitment of the graduates, to assess the key gaps/ issues in design and implementation of PGDPS, and to recommend for further improvement in the program as seen appropriate. Altogether 40 PGDPS graduates from all over Nepal were randomly selected as the sample from the target group which included police inspectors who have received PGDPS since 2005.
