Cross-battery assessment
（重定向自XBA）
Cross-battery assessment refers to the process by which psychologists use information from multiple test batteries (i.e., various IQ tests) to help guide diagnostic decisions and to gain a fuller picture of an individual’s cognitive abilities than can be ascertained through the use of single-battery assessments. The cross-battery approach (XBA) was first introduced in the late 1990s by Dawn Flanagan, Samuel Ortiz and Kevin McGrew. It offers practitioners the means to make systematic, valid and up-to-date interpretations of intelligence batteries and to augment them with other tests in a way that is consistent with the empirically supported Cattell–Horn–Carroll (CHC) theory of cognitive abilities.
