Guarding the Guardians. In order to ensure a fair assessment of test candidates language production, two procedures are typically recommended in the field of language testing: the use of a common rating scale, and the training of raters. These two highly recommended procedures in performance testing have traditionally been viewed as means to heighten reliability of test scores. In line with recent developments, this book argues that the rater variable affects not only reliability, but the very construct validity of test scores. In the study, the scoring of four groups of raters is compared: laypeople (i.e. nonlinguists), teachers without formal rater training, trained raters, and finally a group of very experienced raters. The results reveal differences between groups for the scores they give, as well as for the reasons for these scores and shows that quantitative similarities in ratings may mask significant qualitative differences in the reasons for those ratings (ConnorLinton 1995: 99).
