Concept:Aptitude tests measure a person's potential ability, or what they can do without prior learning. They are most commonly used to guide career and occupation choices.
Explanation:The word "aptitude" means being fitted for something. An aptitude test checks your natural talent or potential, not what you have already learned.
Career counselors use aptitude tests to help students choose suitable courses or jobs.
These tests help a person understand their own abilities and interests.
Educational institutions also use them for admission selection.

Aptitude tests match a person's skills with the requirements of different occupations.
This makes them most significant for vocational guidance, not personal, group, or educational guidance.
