There are four index scores representing major components of intelligence:
* Verbal Comprehension Index (VCI)
* Perceptual Reasoning Index (PRI)
* Working Memory Index (WMI)
* Processing Speed Index (PSI)
Two broad scores are also generated, which can be used to summarize general intellectual abilities:
* Full Scale IQ (FSIQ), based on the total combined performance of the VCI, PRI, WMI, and PSI
* General Ability Index (GAI), based only on the six subtests that comprise the VCI and PRI
