Workplace-Based Assessment in Postgraduate Medical Education: A Narrative Review of Tools, Validity, and Educational Impact

Abstract

Background: Workplace-based assessment (WBA) has become a cornerstone of competency-based medical education, shifting evaluation from artificial testing environments to authentic clinical settings. Tools such as Direct Observation of Procedural Skills (DOPS), Mini-Clinical Evaluation Exercise (mini-CEX), and Case-Based Discussion (CbD) are widely used to assess clinical competence in real time, yet a comprehensive synthesis of their validity, reliability, and educational impact is needed. Objectives: This narrative review aims to evaluate the effectiveness of WBA tools in postgraduate medical education, with a focus on their psychometric properties, feasibility, and role in enhancing clinical skills and professional development. Methods: A narrative review methodology was employed, guided by established frameworks for medical education research. Electronic databases, including PubMed, PMC, and Google Scholar, were searched using terms such as “workplace-based assessment,” “DOPS,” “mini-CEX,” and “postgraduate medical education.” Inclusion criteria encompassed peer-reviewed studies, reviews, and guidelines published in English that discussed the design, implementation, or outcomes of WBA tools. Thematic synthesis was used to analyse and integrate findings. Results: Evidence indicates that WBA tools significantly improve procedural and clinical competencies through structured observation and immediate feedback. DOPS demonstrated marked skill progression, with mean scores increasing from 3.91 to 7.25 in suturing (p < 0.001). Reliability improves with aggregation. DOPS achieves a generalisability coefficient of 0.75, reaching 0.80 after six assessments. WBA is feasible, with DOPS taking approximately 24 minutes (11 min observation, 13 min feedback). Trainees report high acceptability, citing enhanced confidence and skill mastery. Conclusions: WBA is a valid, reliable, and educationally valuable approach when implemented longitudinally and supported by rater training and institutional commitment. It plays a critical role in shaping competent, reflective practitioners within modern medical education frameworks. Future efforts should focus on standardisation, digital integration, and faculty development to maximise its impact. BJME: Vol.-17, Issue-02, July, 2026: 23-36
