The feasibility of reducing scoring costs for the Test of Spoken English (TSE) by using one rater was investigated. Currently, two raters are used. It was found that, because of the possibility of different standards used by potential raters, it does not appear feasible to use a single rater as the sole determiner of speaking proficiency under the current system. Other possible alternatives were also examined. One approach was the development of a quality control index which would predict the extent of the disagreement between two raters, but the index that was developed could not be validated. The best predictors of rater disagreement were the identities of the raters. Their disagreements, however, resulted from the differing standards they used. Raters agreed substantially about the ordering of examinees, but varied slightly in the severity of their ratings. (Author/GDC)
