Clinical competence is multi-dimensional and must be acquired by all medical students. Accordingly, a prospective quasi-experimental study was conducted to evaluate the merging of script concordance testing (SCT) and team-based learning (TBL) as a teaching/learning approach for medical students in clinical settings. The study comprised three phases: Phase 1 (preparatory phase) involved students' preparation and preparation of the SCT. In Phase 2 (implementation phase), the individual and team SCT (iSCT and tSCT, respectively) were applied. In Phase 3 (evaluation phase), the score results were compared, and students' feedback was obtained. The SCT/TBL approach improved the clinical reasoning skills of the students in some vignettes, and the tSCT helped those achieving lower marks improve their performance. The approach supported discussions and helped students correct their mistakes and improve their problem-solving and reasoning skills. The SCT/TBL approach improved students' performance, especially that of those achieving lower marks.
