The Objective Structured Clinical Examination (OSCE) is an established section in the part I examination and in many anaesthetic examinations throughout the world. It enables the examiners to assess a candidate's performance in a variety of areas and in topics that were not previously tested. The first edition sought to give examples of OSCE stations with answers. It was hoped that this would be of benefit to candidates as well as trainers looking for guidance about the type and style of stations that might be encountered. The second edition gives more examples of stations with answers. Candidates should find the answers helpful in assessing the level of knowledge required. Many stations require candidates to have a well-rehearsed system for them like examining the anaesthetic machine, or a system of the body. The second edition has been expanded to include these systems. More background information has been included so that once a system is understood it can be applied to different situations.
