The SAT is a standardized test widely used for college admissions in the United States. Introduced in 1926, its name and scoring have changed several times; originally called the Scholastic Aptitude Test, it was later called the Scholastic Assessment Test, then the SAT I: Reasoning Test, then the SAT Reasoning Test, and now, simply the SAT.

The SAT is owned and published by the College Board, a private, not-for-profit corporation in the United States. It is developed and administered on behalf of the College Board by the Educational Testing Service.
