How does psychological testing work?

Aptitude testing

An aptitude test measures a person’s ability to perform different kinds of tasks. This is done to determine the areas in which their skills are the strongest. Some people may be better with quantitative tasks that require math and logical reasoning skills, some at language, and some at creative thinking.

These tests are used by vocational therapists to measure ability, and figure out the kind of professions or job roles a person may be suited for. They may also be used by career counselors to guide people towards higher education in fields where they demonstrate high ability.
