General Ability Index (GAI), based only on the six subtests that the VCI and PRI comprise; it is intended to portray a snapshot of general intelligence that is less influenced by working memory and processing speed demands.
The 2014 publication of the WISC-V contained five ancillary index scores that may be derived for special clinical purposes or situations: the Quantitative Reasoning Index (QRI), the Auditory Working Memory Index (AWMI), the Nonverbal Index (NVI), the General Ability Index (GAI), and the Cognitive Proficiency Index (CPI).

In addition, the Processing Speed Quotient (known as the Processing Speed Index on previous Wechsler scales) can be derived for children aged 4 – 7 years 3 months, and a General Language Composite can be determined for children in both age bands (2 years 6 months – 3 years 11 months & 4–7 years 3 months). Children in the 2 years 6 months ...
The Cattell–Horn–Carroll theory factors that this test examines are based on 9 broad stratum abilities, although the test is able to produce 20 scores [4] only seven of these broad abilities are more commonly measured: comprehension-knowledge (Gc), fluid reasoning (Gf), short-term memory (Gsm), processing speed (Gs), auditory processing (Ga), visual-spatial ability (Gv), and long-term ...
Math Reasoning: assess the ability to reason mathematically ( e.g. counting, identifying shapes, and solving verbally framed "word problems" [presented both orally and either written or in illustration]). Written Language. Spelling: evaluates the ability to spell (written spelling of dictated letters, sounds and words that are read in sentences).
The g factor [a] is a construct developed in psychometric investigations of cognitive abilities and human intelligence.It is a variable that summarizes positive correlations among different cognitive tasks, reflecting the assertion that an individual's performance on one type of cognitive task tends to be comparable to that person's performance on other kinds of cognitive tasks.
