What is the key difference between aptitude tests and achievement tests?

• A. Aptitude tests measure potential for learning in broad domains; achievement tests assess what has been learned in specific areas.
• B. Aptitude tests measure current grades; achievement tests measure future potential
• C. Aptitude tests measure personality; achievement tests measure IQ
• D. Aptitude tests measure handwriting speed; achievement tests measure reading comprehension

Answer: (A)

The key distinction is about what each test is designed to measure: aptitude tests evaluate potential to learn and solve problems across broad cognitive domains, focusing on abilities that can develop with training, while achievement tests measure the knowledge and skills someone has already learned in specific subject areas, usually tied to a curriculum. This means aptitude tests predict future learning performance and how well someone might handle new tasks, whereas achievement tests show current mastery of taught content. The other ideas don’t fit as well: measuring current grades or future potential is reversed, and mixing in personality or IQ or comparing handwriting speed to reading comprehension moves away from the specific difference between potential for learning and demonstrated learned content.
