Up to the present time, the task of assessing ”clinical skill” in a medical learner involves the individual ”showing how” something is done and consists of observing the learner's performance with patients. In this context, the objective structured clinical examination (OSCE) has become the method of choice based on patient safety, measuring complete learning and carrying out a full assessment. Moreover, OSCE is able to assess all six of the general competencies established by Accreditation Council for Graduate Medical Education. The OSCE is standardized, designed with an objective in mind and consists of structured concepts that allow a fair evaluation of the learner. This article describes the planning and application of OSCEs.
