[Analysis of the discrimination of the final marks after the first computerized national ranking exam in Medicine in June 2016 in France].

INTRODUCTION

The first computerised national ranking exam (cNRE) in Medicine was introduced in June 2016 for 8214 students. It was made of 18 progressive clinical cases (PCCs) with multiple choice questions (MCQs), 120 independent MCQs and 2 scientific articles to criticize. A lack of mark discrimination grounded the cNRE reform. We aimed to assess the discrimination of the final marks after this first cNRE.

METHODS

A national Excel file gathering overall statistics and marks were transmitted to the medical faculties after the cNRE. The mean points deviation between two papers and the percentage of points ranking 75% of students allowed us to analyse marks' discrimination.

RESULTS

The national distribution sigmoid curve of the marks is superimposable with previous NRE in 2015. In PCCs, 72% of students were ranked in 1090 points out of 7560 (14%). In independents MCQs, 73% of students were ranked in 434 points out of 2160 (20%). In critical analysis of articles, 75% of students were ranked in 225 points out of 1080 (21%). The above percentages of students are on the plateau of each discrimination curve for PCCs, independent MCQs and critical analysis of scientific articles.

CONCLUSION

The cNRE reduced equally-ranked students compared to 2015, with a mean deviation between two papers of 0.28 in 2016 vs 0.04 in 2015. Despite the new format introduced by the cNRE, 75% of students are still ranked in a low proportion of points that is equivalent to previous NRE in 2015 (between 15 et 20% of points).
