The SAT (Scholastic Assessment Test) is a standardized test used for US college admissions. It gauges students' readiness for college by assessing math, evidence-based reading, and writing skills. Administered in high school, it offers a common yardstick for colleges to compare applicants. The test has sections for reading, writing & language, and math, with an optional essay. Scores range from 400 to 1600, with the essay scored separately. Some colleges have adopted test-optional policies, granting students flexibility in submitting scores. While the SAT remains a significant factor in admissions, its importance varies among institutions, reflecting changes in educational trends and policies.
