In the area of performance ratings, a persistent problem has been rating errors. Obtaining accurate and reliable performance ratings is a challenge faced in most educational and employment settings. There have been many studies using a variety of criteria that can be used to evaluate the quality of ratings (Dunbar, Koretz, & Hoover, 1991; Haertel, 1990; Linn, Baker, & Dunbar, 1991; Mehrens, 1992; Moss, 1992). Although there is some confusion in the literature regarding the appropriate indices for evaluating the quality of ratings by different raters' bias and their rating errors, there is also a lack of knowledge regarding the quality of rating data from some rater characteristics. Only a few studies could be found in the literature that evaluate, compare, and try to improve the quality of performance ratings by training raters, improving scoring rubrics, and multiple raters. How can rater errors be detected and what strategies can be used to minimize the effects of rater errors in performance ratings to improve the quality of rating? What is the effect of the rater's background (knowledge) on rater reliability? Do rater characteristics (e.g., gender, age, experience, position) affect rating? How about their motivation, trust, and confidence, would they affect ratings? Do trained raters really achieve higher reliability and less rating errors? Are trained raters more consistent across ratings and over time? The purpose of this study is to improve the quality of rating. The following are some ways this study examines the quality of ratings: (1) identify conceptual and operational definitions of rating errors in literature: (2) train raters to reduce rating errors: (3) use appropriate criteria in scoring rubrics: (4) use multiple raters: (5) choose qualified raters based on rater's background and choose raters who fit the purpose of the study. This has implications for research on rater types, and practical implications for rater training, and raises the possibility of adjusting marks to take account of rater effects. If society and the measurement community plan to increase their use of assessment methods that rely on performance ratings, then problems related to rater errors, training raters, and scoring rubrics need to be addressed in order to make a valuable contribution to the type of decisions for which performance rating data are used.
