Proficiency testing for identifying underperforming students before postgraduate education: a longitudinal study.

A multicomponent proficiency-test could detect underperforming students prior to postgraduate GP Training. Students that ranked in the lowest score quartile had a higher likelihood of being labelled as underperforming than students in the highest score quartile. Therefore, a low score in the multicomponent proficiency-test could indicate the need for closer guidance and early remediating actions focusing on both cognitive and non-cognitive competencies.
