Summative assessment of 5th year medical students’ clinical reasoning by script concordance test: requirements and challenges

A 51 case, 158-question, multidisciplinary paper was constructed to assess clinical reasoning in 5th-year. 10–16 experts in each of 7 discipline-based reference panels answered questions on-line. A multidisciplinary group considered reference panel data and data from a volunteer group of 6th Years, who sat the same test, to determine the passing score for the 5th Years.The mean (SD) scores were 63.6 (7.6) and 68.6 (4.8) for the 6th Year (n？=？23, alpha？=？0.78) and and 5th Year (n？=？132, alpha =0.62) groups (p？<？0.05), respectively. The passing score was set at 4 SD from the expert mean. Four students failed.The SCT may be a useful method to assess clinical reasoning in medical students in multidisciplinary summative assessments. Substantial investment in training of faculty and students and in the development of questions is required.
