Effects of Rater Training on the Assessment of L2 English Oral Proficiency

• The main objective of this study was to examine whether a Rater Identity Development (RID)program would increase interrater reliability and improve calibration of scores againstbenchmarks in the assessment of second/foreign language English oral proficiency. Elevenprimary school teachers-as-raters participated. A pretest–intervention/RID–posttest designwas employed and data included 220 assessments of student performances. Two types ofrater-reliability analyses were conducted: first, estimates of the intraclass correlationcoefficient two-way random effects model, in order to indicate the extent to which raterswere consistent in their rankings, and second, a many-facet Rasch measurement analysis,extended through FACETS®, to explore variation regarding systematic differences of raterseverity/leniency. Results showed improvement in terms of consistency, presumably as aresult of training; simultaneously, the differences in severity became greater. Results suggestthat future rater training may draw on central components of RID, such as core concepts inlanguage assessment, individual feedback, and social moderation work.
