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 clinical performance of nursing students, medical students, and residents, as well as faculty teaching performance. It was also used for processing reviews of proposals for Sigma Theta Tau's International Research Congress in 1987. In general, the capabilities of the PR System which make it useful for processing the peer review of abstracts include: (1) the ease and speed with which a new inventory may be implemented; (2) the low cost and speed of data collection; (3) processing and reporting arising from the use of optically scanned rating sheets; and (4) the appropriateness of its reports. Improvements in the peer review process can be obtained through the use of specialized data management and analysis systems. As these systems become more generally available, there may be a concomitant improvement in the reliability and validity of the formal, technical peer review process. (KSA)
