Influence of examiners on the assessments in an OSCE.

February 2008 | Publications

Examiners certainly have some influence on the assessment of examinations. Of practical relevance is whether this results in a serious reduction of objectivity and reliability. The aim of the study was to analyze the following examiner effects in an OSCE:

systematically lower or higher scores
unequal utilization of the scoring scales
and differences in the ability to differentiate between “good” and “bad” candidates (“discriminatory power of examiner”)
