WISC-IV

(Wechsler Intelligence Scale for Children®- Fourth Edition)

Ages 6.0-16.11 years

The WISC-IV provides essential information and critical clinical insights into a child’s cognitive functioning. While maintaining the integrity of the Wechsler® tradition, the WISC®-IV builds on contemporary approaches in cognitive psychology and intellectual assessment, giving you a new, powerful and efficient tool to help develop and support your clinical judgments.

Verbal Comprehension Subtests:

Similarities

The child is presented two words that represent common objects or concepts and describes how they are similar. This subtest measures verbal concept formation and reasoning.

Vocabulary

For picture items, the child names the object presented visually. For verbal items, the child defines words that are presented visually and orally. This subtest measures word knowledge and verbal concept formation.

Comprehension

The child answers questions based on his or her understanding of general principles and social situations. This subtest measures verbal reasoning and conceptualization, verbal comprehension and expression, the ability to evaluate and use past experience, and the ability to demonstrate practical knowledge and judgment.

Information

The child answers questions that address a broad range of general knowledge topics. This subtest measures the ability to acquire, retain, and retrieve general factual information.

Perceptual Reasoning Subtests:

Block Design

While viewing a constructed model or picture, the child uses red-and-white blocks to re-create the design within a specific time limit. This subtest measures the ability to analyze and synthesize abstract visual stimuli.

Picture Concepts

The child is presented with two or three rows of pictures and chooses one picture from each row to form a group with a common characteristic. This subtest measures abstract, categorical reasoning ability.

Matrix Reasoning

The child views an incomplete matrix or series and selects the response option that completes the matrix or series. This subtest measures fluid intelligence, broad visual intelligence, classification and spatial ability, knowledge of part-whole relationships, simultaneous processing, and perceptual organization.

Picture Completion

Working within a specified time limit, the child views a picture with an important part missing and identifies the missing part. This subtest measures visual perception and organization, concentration, and visual recognition of essential details of objects.

Working Memory Subtests:

Digit Span

For Digit Span Forward, the child is read a sequence of numbers and recalls the numbers in the same order. For Digit Span Backward, the child is read a sequence of numbers and recalls the numbers in reverse order. This subtest measures working memory, mental manipulation, cognitive flexibility, rote memory and learning, attention, and encoding.

Letter-Number Sequencing

The child is read a sequence of numbers and letters and recalls the numbers in ascending order and the letters in alphabetical order. This subtest measures sequential processing, mental manipulation, attention, concentration, memory span, and short-term auditory memory.

Arithmetic

Working within a specified time limit, the child mentally solves a series of arithmetic problems. This subtest measures mental manipulation, concentration, attention, short- and long-term memory, numerical reasoning ability, and mental alertness.

Processing Speed Subtests:

Coding

The child copies symbols that are paired with simple geometric shapes or numbers. Using a key, the child draws each symbol in its corresponding shape or box within a specified time limit. This subtest measures processing speed, short-term visual memory, learning ability, psychomotor speed, visual perception, visual-motor coordination, and visual scanning ability. The child completes this subtest using a response booklet, and not on his or her digital device.

Symbol Search

Working within a specific time limit, the child scans a search group and indicates whether one of the symbols in the target group matches. This subtest measures processing speed, short-term visual memory, visual-motor coordination, cognitive flexibility, visual discrimination, psychomotor speed, and speed of mental operation. The child completes this subtest using a response booklet, and not on his or her digital device.

Cancellation

The child scans both a random and a structured arrangement of pictures, and marks target pictures within a specified time limit. This subtest measures processing speed, visual selective attention, vigilance, perceptual speed, and visual-motor ability. The child completes this subtest using a response booklet, and not on his or her digital device.

Instructions are presented the same way as in paper/pencils assessments

Easily record prompts by tapping on the “P” and track the client’s response, marked with a blue bar.
