Introduction: Student selection is important for selecting the best candidates into medical courses.
The Multiple Mini Interview (MMI) is a valid selection tool for the task. The School of Medical
Sciences (SMS), Universiti Sains Malaysia (USM) has employed MMI as a medical admission
tool to select potential candidates into its medical program. Objective: This paper described the
implementation of the MMI and reported the preliminary evaluation data on its validity evidence.
Method: A 9-station MMI (with 5 manned and 4 rest stations) was employed for the 2015 student
selection exercise. Interview data were analysed and questionnaire surveys were administered to both
interviewers and candidates. Validity, reliability, feasibility and acceptability were determined. Results:
Unidimensional construct on confirmatory factor analysis (CFA) and interviewer comments provided
evidence of construct validity. Overall reliability was 0.94, good enough for high-stakes decisions.
Interviewers and candidates’ comments on feasibility and acceptability were also generally positive.
The consistency of the difficulty and discrimination indices of similar stations between sessions was
identified as among the areas for improvement. Conclusions: We are cautiously optimistic regarding
the utility of the MMI in the SMS; future improvements are planned but the present implementation
seems sufficient for the stated purposes
