Evidencing improvement in examiner calibration in OSCEs
New paper from Dr Matt Homer and Vlad Ababei explores the effect of various factors on improving degrees of calibration in OSCE stations.
OSCEs, Objective Structured Clinical Examinations, are used to assess the clinical performance of student doctors through a series of stations designed to test various essential skills. To pass the OSCE, students must achieve a pass score for each station.
In this paper Dr Matt Homer and Vlad Ababei look at the individual stations by employing a quantitative measure of examiner calibration. This allows for the degree of standardisation between individual examiners at each station to be identified. Building upon these results, further qualitative analysis is used to allow for an in-depth understanding of the factors which drive this change.
Results from these analyses provide evidence showing that stations which are newer and have with more detailed and relevant scoring guidance and support materials result in a greater level of calibration between examiners. This demonstrates that key developments in station design, a high quality of support materials, and enhanced examiner training practices can succeed in improving degrees of calibration in OSCE stations.
