Self-adapted testing is a variant of computerized adapted testing in which the examine makes dynamic choices about the difficulty of the items he or she attempts. Self-adapted testing generates scores that are, in constrast to computerized adapted test and fixed-item tests, uncorrelated with a measure of trait test anxiety. This lack of correlation with an irrelevant attribute of the examine is evidence of an improvement in the construct validity of the scores. This improvement comes at the cost of a decrease in testing efficiency. The interaction between test anxiety and test administration mode is more consistent with an interference theory of test anxiety than a deficit theory. Some of the practical concerns regarding self-adapted testing can be ruled out logically, but others await empirical investigation.1 aRocklin, T  uhttp://iacat.org/content/self-adapted-testing-improving-performance-modifying-tests-instead-examinees00403nas a2200097   4500008004100000245007000041210006900111260002100180100001500201856008900216       1989                        eng d00aIndividual differences in item selection in self adaptive testing0 aIndividual differences in item selection in self adaptive testin  aSan Francisco CA1 aRocklin, T  uhttp://iacat.org/content/individual-differences-item-selection-self-adaptive-testing
