Multicenter StudyTwo models of raters in a structured oral examination: does it make a difference?
Oral examinations have become more standardized over recent years. Traditionally a small number of raters were used for this type of examination. Past studies suggested that more raters should improve reliability. ⋯ Reliability was higher for the candidate-specific raters. Inter-rater reliability, internal consistency and a study of station inter-correlations suggested that a halo effect may be present for candidates examined by candidate-specific raters. This study suggests that although the model of candidate-specific raters was more reliable than the model of station-specific raters for the overall examination, the presence of a halo effect may influence individual examination outcomes.

Increased authenticity in practical assessment using emergency case OSCE stations.
In case of an emergency, a fast and structured patient management is crucial for patient's outcome. The competencies needed should be acquired and assessed during medical education. The objective structured clinical examination (OSCE) is a valid and reliable assessment format to evaluate practical skills. ⋯ They rated ECOS to be more realistic in comparison to the traditional OSCE scenarios. The reliability estimated via Crohnbach's alpha for the 6 ECOS is high (0.793). ECOS offer a feasible alternative to the traditional OSCE stations with adequate reliability to assess students' capabilities to cope with an acute emergency in a realistic encounter.
