The PSAT (Preliminary Scholastic Aptitude Test) is a standardized test administered by the College Board and cosponsored by the National Merit Scholarship Corporation (NMSC) in the United States. It is a practice version of the SAT exam and is designed to prepare students for the SAT and gauge college readiness. The PSAT is taken by high school sophomores and juniors, and scores from the PSAT/NMSQT are used to determine eligibility and qualification for the National Merit Scholarship Program.

The PSAT is a low-stakes test unless a student is aiming for a National Merit $2,500 Scholarship or one of the special scholarships. Colleges do not use the PSAT as part of admissions criteria, so taking the test can be a good way to identify shortcomings in a particular subject or to work out testing anxiety. The PSAT is scored on a scale of 320-1520, and the test lasts just under three hours. The exam tests math, reading, and writing abilities, and the topics tested span a variety of subjects.

The PSAT changed its format and content in Fall 2023, continuing the transition to digital tests. The Reading and Writing Sections are combined into one section score, and the Math section now allows calculators on all sections. The PSAT is often taken during the school day, in place of other classes, and the test itself takes about 3 hours, including break time.
