Numerical Reasoning Test

Type of questions: Word problems, tables, graphs, equations, percentages

What it measures: Math understanding, number patterns, and ability to interpret data

Purpose: Often used in business or finance roles where numbers matter. Tests how well you work with figures. 

Verbal Reasoning Test

Type of questions: Reading passages, synonym/antonym matching, word definitions

What it measures: Language understanding, reading comprehension, and verbal logic

Processing Speed Test

Type of questions: Timed symbol matching, simple math or pattern tasks under time pressure

What it measures: How quickly and accurately you can take in and respond to information

Purpose: Often included in neurological tests and cognitive baseline assessments.

Cognitive Flexibility Test (e.g., Wisconsin Card Sorting Test)

Type of questions: You sort cards by shape, color, or number—but the rules change unexpectedly

What it measures: Adaptability, mental flexibility, problem-solving

Purpose: Used to measure executive function, especially after brain injury or in neurological testing.
