Reviews research literature on comparability issues in computerized adaptive testing (CAT) and synthesizes issues specific to comparability and test security. Develops a framework for evaluating comparability that contains three categories of criteria: (1) validity; (2) psychometric property/reliability; and (3) statistical assumption/test…

This paper reports on existing studies and uses meta analysis to compare and synthesize the results of 20 studies from 8 research reports comparing the ability measure equivalence of computer adaptive tests (CAT) and conventional paper and pencil tests. Using the research synthesis techniques developed by Hedges and Olkin (1985), it is possible to…
