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. The test is intended to assess a student's readiness for college.

The Secondary School Admission Test, or SSAT, is an admission test administered by The Enrollment Management Association in the United States to students in grades 3–11 to provide a standardized measure that will help professionals in independent or private elementary, middle, and high schools to make decisions regarding student admission. There are three levels of the test: the Elementary Level (EL), for students in grades 3 and 4 who are applying to grades 4 and 5; the Middle Level, for students in grades 5–7 applying for grades 6–8; and the Upper Level, designed for students in grades 8–11 who are applying for grades 9–12
