Standard setting: a comparison of case-author and modified borderline-group methods in a small-scale OSCE.

Purpose: To compare cut scores resulting from the case-author method and the modified borderline-group method (MBG) of standard setting in an undergraduate objective structured clinical examination (OSCE), and to review the feasibility of using the MBG method of standard setting in a small-scale OSCE.

Method: Sixty-one fourth-year medical students underwent a ten-station OSCE examination. For the eight stations used in this study, cut scores were established using the case-author and MBG methods.
