Human raters and machine scoring systems potentially have complementary strengths in evaluating language ability; specifically, it has been suggested that automated systems might be used to make consistent measurements of specific linguistic phenomena, whilst humans evaluate more global aspects of performance. We report on an empirical study that…

This study examined whether reporting subscores for groups of items within a test section assessing a second-language modality (specifically reading or listening comprehension) added value from a measurement perspective to the information already provided by the section scores. We analyzed the responses of 116,489 test takers to reading and…
