Background: As postgraduate medical or dental education students, most of us will have come across Direct Observation of Procedural Skills or DOPS. DOPS promoted clinical effectiveness by evaluating practice-based skills in the authentic organizational context, and subsequently proactively feeding back the learning to learners. This scoping review sought to synthesize the work done in determining DOPS's effectiveness in enhancing clinical competencies in some fields of medicine and dentistry. Methods: The study was carried out by using the following search engines: PubMed, Medline, Google Scholar, Science Direct, SID, Medlib and Google searched unpublished sources (Gray literature) and selected references (reference of reference) by typing the following keywords: (DOPS), clinical competencies, postgraduate medical and dental education. Results: From 215 papers 40 were analyzed and together demonstrated the efficiency of the Direct Observation of Procedural Skills (DOPS) as an assessment tool for numerous medical and dental profiles. It was revealed that DOPS improved procedural confidence, procedural performance competence and general clinical skills, all over the world. In their views, learners and educators overestimated the usefulness of DOPS and acknowledged its function of enhancing clinical competencies and offering feedback. The participants encountered some difficulties such as time limitations, coordination problems, and curriculum mismatch Nevertheless, DOPS was much more effective than traditional approaches in increasing satisfaction and reliability of the assessments in various medical training settings. Conclusion: In the context of postgraduate medical and dental education and training, the DOPS assessment tool was found to be very effective in enhancing clinical competencies and procedural skills. However, the successful implementation has the points that need to be attended like the training of the assessors and standardization although there are benefits of the same. Further studies were encouraged to investigate ways of enhancing the use of DOPS and how best it could be incorporated into post-graduate training
