Abstract
In this study, we explored the effects of rater background, scoring training, and grading criteria on rater reliability in evaluating Chinese students� written essays. We selected eight selected raters and divided them into two experimental and two control groups to collect data, which was then analyzed via SAS statistical software, Pearson Consistent analysis among the four groups, T-test, and analysis of variance (ANOVA). The results of the experiment showed that scoring training had a significant effect on the essay grading, while rater background and grading criteria had no effect.
