IQ Final WAIS & WISC Overview

WISC

An intelligence test for children aged 6 to 16 years and 11 months.

WAIS

An intelligence test for individuals aged 16 to 93 years and 11 months.

FSIQ

Full Scale Intelligence Quotient that measures general cognitive ability.

WAIS-IV Index Scores

Includes four indices: Verbal Comprehension, Working Memory, Perceptual Reasoning, and Processing Speed.

WISC-V Index Scores

Includes five indices: Verbal Comprehension, Visual Spatial, Fluid Reasoning, Working Memory, and Processing Speed.

Verbal Comprehension (WAIS-IV)

Measures ability to understand, use, and think with spoken language.

Working Memory (WAIS-IV)

Measures ability to attend to and manipulate verbal information.

Perceptual Reasoning (WAIS-IV)

Measures fluid reasoning in the perceptual domain.

Processing Speed (WAIS-IV)

Measures ability to process simple information quickly.

Verbal Comprehension (WISC-V)

Measures child's verbal reasoning and crystallized intelligence.

Visual Spatial (WISC-V)

Measures nonverbal reasoning, perception, and visual-motor coordination.

Fluid Reasoning (WISC-V)

Measures quantitative reasoning and ability to solve novel problems.

Normative Strengths

Scores above 115 indicating relative strengths compared to the population.

Normative Weaknesses

Scores below 85 indicating relative weaknesses compared to the population.

Personal Strengths

Strengths identified from an individual's cognitive profile comparing different index scores.

Personal Weaknesses

Weaknesses identified from an individual's cognitive profile comparing different index scores.

FSIQ Interpretation

Interpret when there are fewer than 23 points difference between composite scores.

GAI

General Ability Index, used when there is a significant difference in composite scores.

Low Index Subtest Scatter

Indicates high confidence in test interpretation.

High Subtest Scatter

Indicates potential concerns about interpretation.

WAIS-V Updates

Includes a revised model, two new indices, and five new subtests.
