Following is a list of the kinds of questions that appear on one of the standardized IQ tests for children. A similar list with examples of each is available here:

Arithmetic—the student is presented a set of arithmetic problems that they solve mentally (i.e., no pencil and paper) and answer orally. This subtest involves numerical reasoning ability, mental manipulation, concentration, and auditory memory.

Block Design—the student reproduces a series of geometric patterns using red-and-white blocks. This subtest measures the ability to analyze and synthesize abstract visual stimuli, nonverbal concept formation, and perceptual organization.

Cancellation—the student scans sequences of visual stimuli and marks target forms. This subtest involves processing speed, visual attention, and vigilance.

Coding—the student matches and copies symbols that are associated with either objects (i.e., Coding A) or numbers (Coding B). This subtest is a measure of processing speed, short-term visual memory, mental flexibility, attention, and motivation.

Comprehension—the student responds to questions that are presented orally involving everyday problems or social situations. This subtest is a measure of verbal comprehension and reasoning as well as the ability to apply practical information.

Digit Span—the student is presented orally sequences of numbers that they repeat verbatim (i.e., Digits Forward) or in reverse order (i.e., Digits Backwards). This subtest involves short-term auditory memory, attention, and on Digits Backwards, mental manipulation.

Information—the student responds to questions that are presented orally involving a broad range of knowledge (e.g., science, history, and geography). This subtest measures the student's general fund of knowledge.

Letter-Number Sequencing—the student reads a list of letters and numbers and then recalls the letters in alphabetical order and the numbers in numerical order. This subtest involves short-term memory, sequencing, mental manipulation, and attention.

Matrix Reasoning—the student examines an incomplete matrix and then selects the item that correctly completes the matrix. This subtest is a measure of fluid intelligence and is considered a largely language-free and culture-fair measure of intelligence.

Picture Completion—the student is presented a set of pictures and must identify what important part is missing. This subtest measures visual scanning and organization as well as attention to essential details.

Picture Concepts—the student examines rows of objects and then selects objects that go together based on an underlying concept. This subtest involves nonverbal abstract reasoning and categorization.

Similarities—two words are presented orally to the student and the student must identify how they are similar. This subtest measures verbal comprehension, reasoning, and concept formation.

Symbol Search—the student scans groups of symbols and indicates if a target symbol is present. This subtest is a measure of processing speed, visual scanning, and concentration.

Vocabulary—the student is presented orally a series of words that the student must define. This subtest is primarily a measure of word knowledge and verbal conceptualization.

Word Reasoning—the student must identify the underlying or common concept that is implied by a series of clues. This subtest involves verbal comprehension, abstraction, and reasoning
