The book aims to be an up-to-date reference for those using the WISC-IV for clinical purposes. For each subtest, the functional demand, measurement goals, and the most important variables in test administration are identified.

The interpretation adopts modern reading criteria based on the clinical comparison between WISC-IV scores and those obtained from a study of 497 Italian children with the most common clinical disorders, as well as from key literature data. The names of factors and indices examined in the text refer to the latest update of CHC theory.

According to the most recent explanations, the non-interpretable nature of the IQ index is transcended. Based on the author's rigorous fieldwork and ten years of clinical experience, this new book on the WISC-IV remains faithful to David Wechsler's philosophy of the scales: "Primarily, clinical tests – not psychometric tests, but clinical tests," for which the need was to place the individual as a whole at the center of assessment, rather than focus on a specific characteristic, in order to obtain valid psychological indicators.
