Influence of a revision course and the gender of examiners on the grades of the final ENT exam--a retrospective review of 3961 exams.
Revision courses should repeat already acquired knowledge and skills and mostly provide a basis for passing the following exam.


OBJECTIVE
The aim of the study is to investigate the influence of a previously attended revision course on the grades achieved in a final exam (Ear, Nose and Throat Diseases). Additionally we ask the question whether the gender of the examiners plays a role concerning the marks or not.


METHODS
3961 exams at the Department of Ear, Nose and Throat (ENT) Diseases in Vienna were investigated, 725 with revision course (experimental group) and 3236 without previous revision course (comparison group). The revision courses were performed in a standardized way concerning form and content, interactive and case based. Both groups were examined uniform in regard to topics and time duration. 16 male and 6 female examiners were involved. The grading followed a five-level scale. The examination marks were calculated in the arithmetic mean and median value for the entire sample, gender dependence was calculated according to the Wilcoxon-Mann-Whitney-Test. The inferential statistics included single- and multiple factorial analyses of variance as well as uni- and multivariate regression models.


RESULTS
The experimental group achieved a grade average of 2.54 compared with 2.46 for the comparison group. Splitting up into male and female examiners, an average of 2.54 and 2.58 resp. for the experimental group and 2.44 and 2.61 resp. for the comparison group resulted. Female examiner marked significantly lower grades in comparison to their male colleagues (P= 0.001926).


CONCLUSIONS
The ENT revision course did not improve the grade averages of the final ENT exam. Female examiners grade stricter than male examiners. There was no difference concerning grades 4 (pass) and 5 (fail) but female examiners grade less with mark 1.
