There are three letters every high school student must learn: S, A, and T. Who is responsible for making those letters so infamous? Why, The College Board, of course. The not-for-profit association owns and administers the Scholastic Assessment Test (SAT), College-Level Examination Program (CLEP), and the Advanced Placement Program (AP) at high schools nationwide. It also offers guidance counseling, financial aid, student assessment, standardized testing, and professional development courses. The College Board was founded in 1900; its members include nearly 6,000 schools, colleges, universities, and other educational institutions.
