The SAT Reasoning Test is a standardized test for college admissions in the United States. The SAT is owned, published, and developed by the College Board, a not-for-profit organization in the United States. It was formerly developed, published, and scored by the Educational Testing Service which still administers the exam.

The test is intended to assess a student's readiness for college. It was first introduced in 1926, and its name and scoring have changed several times. It was first called the Scholastic Aptitude Test, then the Scholastic Assessment Test, but now SAT does not stand for anything.
