What subtests make up FSIQ on WAIS-IV?
The WAIS-IV has 10 core subtests (Arithmetic, Block Design, Comprehension, Digit Span, Digit Symbol, Information, Letter-Number Sequencing, Matrix Reasoning, Picture Arrangement, Picture Completion, Processing Speed, Object Assembly, Similarities, Symbol Search, and Vocabulary) which make up four index scores.
Does WAIS-IV measure IQ?
It is currently in its fourth edition (WAIS-IV) released in 2008 by Pearson, and is the most widely used IQ test, for both adults and older adolescents, in the world.

What are the subtests of an IQ test?
These are called Verbal Comprehension, Visual Spatial, Fluid Reasoning, Working Memory, and Processing Speed. Each Index Scale is comprised of two subtests that together make up the scale result.
Is FSIQ the same as IQ?
A Full-Scale Intelligence Quotient (FSIQ) is generated based on seven subtests: Similarities, Vocabulary, Block Design, Matrix Reasoning, Figure Weights, Digit Span, and Coding. When we talk about an individual’s “IQ,” we are generally referring to their FSIQ score.
How does the WAIS measure intelligence?
The WAIS-IV comprises a full scale IQ, as well as indexes on four factors: verbal comprehension, perceptual reasoning, working memory and processing speed. Table 7 includes the core tests for each factor.
What does Matrix reasoning measure on the WAIS-IV?
It measures nonverbal reasoning skills and taps into thinking that is more fluid and requires visual perceptual abilities. This index reflects an individual’s ability to take in and hold information in immediate awareness and then perform a mental operation on that information.
How many subtests are on the WAIS IV?

What is the IQ range on the WAIS-IV?
The WAIS-IV contains 10 core subtests and 5 additional optional subtests. These are summed to four indexes: Processing Speed Index. One Full Scale IQ (FSIQ) is also calculated. These scores range from the lowest (40) to the highest (160) points.
What is the purpose of the WAIS IV Index?
DESCRIPTION OF WAIS-IV INDEXES Verbal Comprehension Index This index reflects an individual’s ability to understand, use and think with spoken language.
