Subject Tests (formerly SAT II: Subject Tests) are designed to measure your knowledge and skills in particular subject areas, as well as your ability to apply that knowledge.
Students take the Subject Tests to demonstrate to Colleges their mastery of specific subjects like English, history, mathematics, science, and language. The tests are independent of any particular textbook or method of instruction. The tests' content evolves to reflect current trends in high school curricula, but the types of questions change little from year to year.
Many Colleges use the Subject Tests for admission, for course placement, and to advise students about course selection. Used in combination with other background information (your high school record, scores from other tests like the SAT Reasoning Test, teacher recommendations, etc.), they provide a dependable measure of your academic achievement and are a good predictor of future performance.
Some Colleges specify the Subject Tests they require for admission or placement; others allow applicants to choose which tests to take.
ALWAYS VERIFY THE INDIVIDUAL TEST REQUIREMENTS FOR ANY College YOU ARE CONSIDERING.
Subject Tests fall into five general subject areas:
