Introduction
Objective structured clinical examination (OSCE) results could be affected by low homogeneity of examiners, non-retrospectiveness of test results, and examiner-cohort effect. In China, many students participate in medical qualification examinations, and this issue is particularly significant. This study aimed to develop a video recording, video-based rating method and compare the reliability of video and on-site ratings to enhance the quality assurance of OSCEs.
