Background: Clinical education is the heart of medical education. It is one of the most important manifestations of teaching and learning in professions relating to medical sciences, leading to learners' clinical competency. This study was done to investigate general physician graduates' knowledge, performance, and clinical competency before entering the field of clinical activities.Methods: In this descriptive cross-sectional study, the scores of different stations of the Objective Structured Clinical Examination (OSCE), held at the end of the general medicine course in Iran, were collected at Mashhad University of Medical Sciences. Totally, ۲۶۶ students who participated in six periodicities of clinical competency examinations were included in the study by the census method. The clinical competency of general physician graduates assessed in the scopes were determined by the General Medical Education Council, including problem-solving, communication skills, practical action, taking the history, and performing physical examinations by the OSCE. The data were analyzed by SPSS software using descriptive and inferential statistics.Results: The effect of different scopes of the OSCE (F(۳,۵۶۵۲) = ۷.۰۲۲ and P = ۰.۰۰۱) and participants' performance based on their critical and non-critical indicators (T = ۱.۹۷۶ and P = ۰.۰۴) are significant with ۹۵% confidence interval. This suggests that participants' performance varies in different scopes of the clinical examination, including problem-solving, communication skills, practical action, taking the history, and performing physical examinations.Conclusions: The differences in the clinical competencies of general physician graduates in mentioned scopes were significant. This emphasizes the need to examine their essential skills to achieve the minimum competencies expected of a future physician before entering the field of clinical activity.
