    Journal: J Physician Assist Educ; 2010; 21(2):7-14. PubMed ID: 21141047.
    Abstract:
    PURPOSE: this study explored the reliability of two simple standard-setting methods that are used to set passing standards for a standardized patient (SP) exam in physician assistant (PA) education. METHODS: fifty-four second-year PA students participated in a multistation SP-based clinical skills exam. Cut scores were set using the Angoff and Borderline Group methods. A panel of PA faculty set cut scores using the Angoff method. A modified version of the Borderline Group method set cut scores using SP global ratings verified by faculty review. Inter-rater reliability between judges was evaluated using kappa coefficient (k) for the Angoff method and intraclass correlation coefficient (ICC) for the Borderline Group method. RESULTS: the Borderline Group method set an overall cut score for the exam of 76% (95% CI +/- 5) and the Angoff method set a cut score at 62% (95% CI +/- 9). Both methods demonstrated sufficient inter-rater reliability (k 0.60, ICC > 0.70; both significant at p < 0.05), although one case (preop history and physical) demonstrated poor inter-rater reliability between judges using the Borderline Group method. DISCUSSION: the Borderline Group method offered a slightly more reliable cut score when compared to the standard set by the Angoff method, but was more challenging to implement. In addition, one case demonstrated poor inter-rater reliability with the Borderline Group method. Using SPs to complete global borderline ratings offers one solution to make the Borderline Group method more feasibile, but requires a high degree of initial rater calibration and periodic measures of interrater reliability between faculty and SPs.
