An aptitude test is designed to predict future performance in a particular domain. Which option best describes this purpose?

• A. An exam predicting past achievement
• B. A test predicting future performance in a domain
• C. A test of reading comprehension
• D. A measure of social skills

Answer: (B)

Aptitude tests aim to predict a person’s potential to perform well in a given area based on their ability to learn and apply new skills, not on what they already know. This predictive focus is what makes them useful for forecasting future performance in a domain. The best choice describes this purpose exactly: it’s about future potential rather than past knowledge. The other options describe current knowledge or abilities—predicting past achievement, testing reading comprehension, or measuring current social skills—which do not capture the idea of forecasting future performance in a specific field.
