A test measures what a student knows or can do. It can be short or long, written or oral, practical or theoretical. Tests are used for grades, placement, certification, and admission. They are one of the most common tools in education.

Tests come in many formats. Multiple choice is efficient and easy to score. Essays reveal reasoning but take hours to grade. Performance tests ask students to do something, like play an instrument or fix a circuit. Each format has strengths and blind spots.

Critics argue that tests narrow learning and reward memorization over understanding. Supporters say they provide objective data and hold schools accountable. The truth is that tests are tools. A well-designed test can reveal misunderstanding. A poorly designed one measures test-taking skill more than knowledge.
