title: Challenging medical students with an interim assessment: a positive effect on formal examination score in a randomized controlled study.
abstract: Until now, positive effects of assessment at a medical curriculum level have not been demonstrated. This study was performed to determine whether an interim assessment, taken during a small group work session of an ongoing biomedical course, results in students' increased performance at the formal course examination. A randomized controlled trial was set up, with an interim assessment without explicit feedback as intervention. It was performed during a regular biomedical Bachelor course of 4 weeks on General Pathology at the Radboud University Nijmegen Medical Centre. Participants were 326 medical and 91 biomedical science students divided into three study arms: arm Intervention-1 (I-1) receiving one interim assessment; arm I-2 receiving two interim assessments, and control arm C, receiving no interim assessment. The study arms were stratified for gender and study discipline. The interim assessment consisted of seven multiple-choice questions on tumour pathology. Main outcome measures were overall score of the formal examination (scale 1-10), and the subscore of the questions on tumour pathology (scale 1-10). We found that students who underwent an interim assessment (arm I) had a 0.29-point (scale 1-10) higher score on the formal examination than the control group (p = 0.037). For the questions in the formal examination on tumour pathology the score amounted to 0.47 points higher (p = 0.007), whereas it was 0.17 points higher for the questions on topics related to the previous 3 weeks. No differences in formal examination score were found between arms I-1 and I-2 (p = 0.817). These findings suggest that an interim assessment during a small group work session in a randomized study setting stimulates students to increase their formal examination score.
