A theory is discussed in which observed performance ratings are derived from the distance between a rater reference point and subject performance point located on a postulated equal-interval scale and a postulated s-shaped rater characteristic curve, operationalized as the normal ogive. Least-squares estimates of rater (nR=47, 31, and 29) and…

To minimize the effects of systematic differences in raters' standards of clinical competence, a handicapping system was applied to the ratings made by fourteen preceptors of 128 junior year medical students in a 6-week psychiatry clerkship at the University of Arkansas for Medical Sciences. The handicap of a preceptor was the difference between…

Cason, Gerald J. – 1981
A substantial and indispensable portion of the training of health professionals must be conducted in clinical settings and is performance oriented rather than cognitively oriented. Evaluation methods usually require reliance upon check lists and rating scales and capture a large volume of information in order to accurately reflect the complexity…

A more familiar and efficient method for estimating the parameters of Cason and Cason's model was examined. Using a two-step analysis based on linear regression, rather than the direct search interative procedure, gave about equally good results while providing a 33 to 1 computer processing time advantage, across 14 cohorts of junior medical…

Prior research in a single clinical training setting has shown Cason and Cason's (1981) simplified model of their performance rating theory can improve rating reliability and validity through statistical control of rater stringency error. Here, the model was applied to clinical performance ratings of 14 cohorts (about 250 students and 200 raters)…

The Objective Test Scoring and Performance Rating (OTS-PR) system is a fully integrated set of 70 modular FORTRAN programs run on a VAX-8530 computer. Even with no knowledge of computers, the user can implement OTS-PR to score multiple-choice tests, include scores from external sources such as hand-scored essays or scores from nationally…
