The "Advanced Clinical Solutions (ACS) for the Wechsler Adult Intelligence Scale-Fourth Edition" ( WAIS-IV Wechsler, 2008) and the "Wechsler Memory Scale-Fourth Edition" (WMS- IV Wechsler, 2009) was published by Pearson in 2009.

Results also suggest a lack of cross-age invariance resulting from age-related differences in factor loadings. Additionally, the WAIS-IV provides a measure of quantitative reasoning (QR). Broad CHC abilities measured by the WAIS-IV include crystallized ability (Gc), fluid reasoning (Gf), visual processing (Gv), short-term memory (Gsm), and processing speed (Gs), although some of these abilities are measured more comprehensively than are others. Results suggest that a Cattell-Horn-Carroll (CHC)-inspired structure provides a better description of test performance than the published scoring structure does. In this study, the structure and cross-age invariance of the latest WAIS-IV revision were examined to (a) elucidate the nature of the constructs measured and (b) determine whether the same constructs are measured across ages. Published empirical evidence for the Wechsler Adult Intelligence Scale-Fourth Edition ( WAIS-IV) does not address some essential questions pertaining to the applied practice of intellectual assessment.

The Wechsler Adult Intelligence Scale-Fourth Edition ( WAIS-IV-ID) has been adapted and proved to be valid for its internal structure for Indonesian population.
