What’s the Difference Between the SAT and ACT?

When it comes to standardized testing for college admissions, most students have heard of the SAT and ACT, but what exactly sets them apart? Understanding the key differences can help you decide which test better suits your strengths and strategy.

Overview of Each Test

The SAT, administered by the College Board, and the ACT, administered by ACT Inc., are both widely accepted by U.S. colleges. However, they differ in structure, content, and timing:

  • The SAT includes sections on Reading, Writing & Language, and Math (with and without a calculator).
  • The ACT includes English, Math, Reading, and Science Reasoning. It also offers an optional Writing section, though most schools no longer require it.

Content and Skills Emphasized

Each test evaluates a slightly different skill set:

  • The SAT leans toward evidence-based reasoning and vocabulary-in-context.
  • The ACT tests grammar rules more directly and includes more advanced math concepts, including some trigonometry.
  • The ACT Science section is unique, testing your ability to interpret data, charts, and experiments, not specific science knowledge.

Timing and Pacing

One of the biggest differences is how quickly you need to move:

  • SAT: Fewer questions but more time per question.
  • ACT: More questions in less time, requiring faster reading and decision-making.

If you work more slowly but carefully, the SAT may be better. If you’re comfortable with a fast pace and broad content, the ACT could be a fit.

Scoring Differences

  • The SAT is scored on a scale of 400 to 1600.
  • The ACT uses a scale of 1 to 36 for each section, averaged for a composite score.

Colleges understand both tests equally, and many will “superscore” by combining your best section results from different test dates.

How to Choose the Right Test

Try a few practice sections from each test. If one feels more intuitive or manageable, lean in that direction. Some students take both and submit their better score, but you don’t have to.

Also consider:

  • Some states offer one test for free in school.
  • Test dates and locations might differ in your area.
