Cason, Gerald J.; Cason, Carolyn L. – 1989
The use of three remedies for errors in the measurement of ability that arise from differences in rater stringency is discussed. Models contrasted are: (1) Conventional; (2) Handicap; and (3) deterministic Rater Response Theory (RRT). General model requirements, power, bias of measures, computing cost, and complexity are contrasted. Contrasts are…

Cason, Gerald J.; Cason, Carolyn L. – 1987
This study describes a computer based, performance rating information processing system, performance rating theory, and programs for the application of the theory to obtain ratings free from the effects of reviewer stringency in reviewing abstracts of conference papers. Originally, the Performance Rating (PR) System was used to evaluate the…

Cason, Gerald J.; And Others – 1985
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.; Cason, Carolyn L. – 1985
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…

Cason, Gerald J.; And Others – 1987
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…
