Definition: The SAT is the most widely used standardized test for college admissions. The exam is created and administered by CollegeBoard. It covers three subject areas: critical reading, mathematics and writing. Students have 3 hours and 45 minutes to complete the exam. Each section is worth 800 points, so the highest possible score is 2400. The exam is offered seven times a year: January, March, May June, October, November and December. The SAT is designed to measure critical thinking and problem solving skills that are essential for success in college. The average scores for different colleges vary widely. The other standardized test accepted by most colleges is the ACT.
