Correlation between task-based checklists and global rating scores in undergraduate objective structured clinical examinations in Saudi Arabia: a 1-year comparative study

Both checklists and GRS exhibit reliable psychometric properties. Their combined use improves validity in OSCE scoring, but station-specific application is recommended. Checklists may anchor pass/fail decisions, while GRS may assist in assessing borderline performance. This hybrid model increases fairness and reflects clinical authenticity in competency-based assessment.
