The time seemed right for a third edition, since even over the relatively brief period of ten years, many tests described in the second edition have been replaced, and are no longer commonly used. Major revisions have appeared of established tests, notably the Wechsler intelligence scales. There are many new tests, new applications of established tests, and new test systems. The second edition of this Handbook, published in 1990, appeared at the beginning of a decade marked by extensive advances in assessment in essentially all of its specialized areas. The field of psychological assessment has been undergoing rapid change. The new, theory-based interpretive approach for theWAIS?-III makes this a vital resource for practicing psychologists,as well as a comprehensive text for graduate students. Assessing Adolescent and Adult Intelligence remains the premierresource for the field, covering not only the WAIS?-III but alsothe WJ III?, the KAIT, and several brief measures of intelligence,as well as laying out a relevant, up-to-date discussion of thediscipline. In addition to adetailed description, the authors provide a blank interpretiveworksheet to help examiners make the calculations and decisionsneeded for applying the additional steps of the new system, andnorms tables for the new WAIS?-III subtest combinations added inthis approach. Four appendices present the new method in depth. Following Flanagan and Kaufman's work to develop asimilar CHC approach for the WISC?-IV, Kaufman and Lichtenbergerhave applied this system to the WAIS?-III profile of scores alongwith integrating recent WAIS?-III literature. This approachcombines normative assessment (performance relative to age peers)with ipsative assessment (performance relative to the person's ownmean level). Augmenting the traditional "sequential" and "simultaneous"WAIS?-III interpretive methods, the authors present a new approachderived from Cattell-Horn-Carroll (CHC) theory. The newly updated ThirdEdition provides important enhancements and additions thathighlight the latest research and interpretive methods for theWAIS?-III. The classic text-now updated with a new interpretive approach tothe WAIS?-III Assessing Adolescent and Adult Intelligence, the classic text fromAlan Kaufman and Elizabeth Lichtenberger, has consistently providedthe most comprehensive source of information on cognitiveassessment of adults and adolescents.
