Description: The judgmental policy capturing (JPC) method is a standard setting process that asks judges to consider multiple dimensions of performance and use information about candidates' scores on those dimensions to make decisions about candidates' mastery or overall level of performance. The JPC approach allows insight into judges' decision making policies through the use of dimension-specific weighting coefficients derived from their decisions. This research was designed to determine the effect of working at one versus two cutpoints (i.e., the decision condition) on (a) intra-judge consistency; (b) inter-judge consistency; (c) judges' stringency; (d) the captured policies of the standard setting judges. Additionally, the effect of the cutpoint at which they are working on judges' policies for making mastery decisions was evaluated. Judges reviewed a series of simulated candidate score profiles depicting performance on five dimensions of clinical competence. They made classification decisions about each profile, and these decisions were used to create weighting coefficients to describe individual judges' decision making strategy. In three separate studies judges made classification decisions under one of four conditions: (a) one cutpoint only; (b) lower cutpoint then higher cutpoint; (c) higher cutpoint then lower cutpoint; or (d) both cutpoints simultaneously. The raw judgments, the pass rates and the derived policies were then subjected to both parametric and non-parametric statistical analyses. These analyses evaluated the effect of occasion, cutpoint, order of presentation of cutpoint, and decision condition (consecutive binary versus concurrent ordinal) on these three prime outcomes. Analysis of judges' profile-stimulated decisions would suggest that (1) individual judges are reasonably consistent in their decisions over occasions, regardless of decision condition; (2) judges' derived policies (weighting coefficients) are largely unaffected by the cutpoint at which decisions are being made, regardless of the decision condition; (3) all five dimensions of performance considered in this context are, on average, weighted fairly equally; however, (4) concurrent decision making does appear to affect the difference in cutscores, perhaps more so at the upper level of performance. The estimates of judges' decision policies, as represented by weighting coefficients, appear to be robust to effects of cutpoint and decision condition. However, the judges' cutpoints are affected by decision condition. This finding has implications for other standard setting methods in other contexts where multiple cutscores are required.
