SAT vs PSAT: What's the Difference?
The SAT and the PSAT are built on the same digital, adaptive engine and feel nearly identical while you take them. What differs is their purpose: one is used by colleges for admissions, the other is a practice-and-qualifying test. Getting the distinction right helps you plan which test to take, and when.
Different jobs
The SAT is a college-admissions test — the score colleges see and use. The PSAT family (PSAT 8/9, PSAT 10 and PSAT/NMSQT) is a set of practice tests that track progress and, in the case of the junior-year PSAT/NMSQT, qualify students for the National Merit Scholarship. Colleges do not use PSAT scores for admissions.
Scoring and difficulty
Both are scored out of two equal sections, but on different scales. The SAT tops out at 1600 (two 800-point sections); the PSAT/NMSQT tops out at 1520 (two 760-point sections). The PSAT is pitched slightly easier because it targets younger students, but the content domains and question styles are the same, which is why PSAT prep transfers almost perfectly to the SAT.
- SAT: scored 400–1600. Used for college admissions.
- PSAT/NMSQT: scored 320–1520. Qualifies juniors for National Merit via the Selection Index (48–228).
- PSAT 8/9 and PSAT 10: lower-stakes practice tests; they do not count for National Merit.
When students take each
PSAT 8/9 is typically taken in Grades 8–9, PSAT 10 in Grade 10, and the PSAT/NMSQT in Grade 11 (this is the National Merit year). The SAT is usually taken in Grade 11 and again in Grade 12, so students can superscore or improve. Many families use the PSAT sequence as a low-pressure on-ramp to a strong SAT.
Bottom line
Take the PSAT to practise and — in junior year — to compete for National Merit. Take the SAT for admissions. Because the skills are shared, the smartest approach is one continuous prep track: strengthen the underlying skills once and they lift both scores.

Frequently Asked Questions
Does the PSAT count for college admissions?
No. Colleges use SAT (and ACT) scores for admissions, not PSAT scores. The PSAT is a practice test, and the junior-year PSAT/NMSQT also serves as the National Merit qualifier.
Is the PSAT easier than the SAT?
Slightly. It covers the same content domains and question types but is pitched a little easier and scored on a 320–1520 scale instead of 400–1600, because it targets younger students.
Do I need to take the PSAT before the SAT?
No, it is not required. But the PSAT is excellent low-stakes practice, and the junior-year PSAT/NMSQT is the only way to qualify for National Merit, so most college-bound students take it.
Does PSAT prep help my SAT score?
Yes — almost entirely. The two tests share content domains, question styles and the adaptive format, so skills you build for the PSAT transfer directly to the SAT.
