The SAT is a standardized test widely used for college admissions in the United States. It was first introduced in 1926, and its name and scoring have changed several times, being originally called the Scholastic Aptitude Test, then the Scholastic Assessment Test, then the SAT Reasoning Test, and now simply the SAT.
The SAT is owned and published by the College Board, a private, nonprofit organization in the United States. It is developed and administered on behalf of the College Board by the Educational Testing Service. The test is intended to assess a student’s readiness for college.
The SAT is offered seven times a year in the United States; in October, November, December, January, March (or April, alternating), May, and June. The test is typically offered on the first Saturday of the month for the November, December, May, and June administrations. In other countries, the SAT is offered on the same dates as in the United States except for the first spring test date (i.e., March or April), which is not offered. The test was taken by 1,672,395 high school graduates in the class of 2014.
