SAT Reasoning Test
The SAT is a standardized test for college admissions in the United States. TheSAT is owned, published, and developed by the College Board, a nonprofit organization in the United States. It was formerly developed, published, and scored by the Educational Testing Service[1] 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 firstcalled the Scholastic Aptitude Test, then the Scholastic Assessment Test, but now SAT does not stand for anything, hence is an empty acronym.
The current SAT Reasoning Test, introduced in 2005, takes three hours and forty-five minutes to finish, and costs $49 ($75 International), excluding late fees.[2] Possible scores range from 600 to 2400, combining test results from three 800-point sections(Mathematics, Critical Reading, and Writing).
Taking the SAT or its competitor, the ACT, is required for freshman entry to many, but not all, universities in the United States.[3]

The College Board states that the SAT measures literacy and writing skills that are needed for academic success in college. They state that the SAT assesses how well the test takers analyze and solve problems—skills they learned in school thatthey will need in college. The SAT is typically taken by high school sophomores, juniors and seniors.[4] Specifically, the College Board states that use of the SAT in combination with high school grade point average (GPA) provides a better indicator of success in college than high school grades alone, as measured by college freshman GPA. Various studies conducted over the lifetime of the SAT show astatistically significant increase in correlation of high school grades and freshman grades when the SAT is factored in.[5]
There are substantial differences in funding, curricula, grading, and difficulty among U.S. secondary schools due to Americanfederalism, local control, and the prevalence of private, distance, and home schooled students. SAT (and ACT) scores are intended to supplement thesecondary school record and help admission officers put local data—such as course work, grades, and class rank—in a national perspective.[6]
Historically, the SAT has been more popular among colleges on the coasts and the ACT more popular in the Midwest and South. There are some colleges that require the ACT to be taken for college course placement, and a few schools that formerly did not accept...
