Test score comparison tables: How well are they serving test users?

While several test concordance tables have been published, the research underpinning such tables has rarely been examined in detail. This study aimed to survey the publically available studies or documentation underpinning the test concordance tables of the providers of four major international language tests, all accepted by the Australian Department of Home Affairs for Australian visa purposes. To evaluate the concordance studies, we first identified the good practice principles in concordance research through a review of both the relevant literature and leading professional standards in the field of educational measurement and language assessment. Next, we reviewed the concordance studies against the identified good practice principles. Our findings revealed that the information supplied by test providers varied, with some making the full research papers available, whereas others providing little information about their underpinning research. None of the concordance studies fulfilled all the good practice principles. Based on the findings of this study, we offer recommendations for future concordance research in the field of language testing as well as suggestions for practice.
