Abstract

Recently, there has been an increasing level of interest in reporting subscores. This paper examines the issue of reporting subscores at an aggregate level, especially at the level of institutions that the examinees belong to. A series of statistical analyses is suggested to determine when subscores at the institutional level have any added value over the total scores. The methods are applied to two operational data sets. For the data under study, the results provide little support in favor of reporting subscores for either examinees or institutions.
