Calculator Policy

beginning of content:

You’re allowed to use a calculator for part of the Math Test — but there’s more to it than making sure you’ve got a fresh set of batteries.

Important:

Bring Your Own Calculator

Calculators are not provided at the test center, and you can’t share a calculator.

Quick Facts

  • Only the calculators listed on this page are acceptable for the Math Test — Calculator portion of the test.
  • You may not use a calculator while working on the Reading, Writing and Language, or Math Test — No Calculator portions, and must put the calculator away during these sections of the test.
  • You will be dismissed and your scores canceled if you use your calculator to share information during the test, or to remove test questions or answers from the test room.

Calculator Smarts

  • Bring your own calculator. You can’t share one.
  • Don’t bring a brand-new calculator. Bring one you know. Practice for the test using the same calculator you’ll use on test day.
  • The Math Test includes some questions where it’s better not to use a calculator, even though you’re allowed to.
  • It may help to do scratch work in the test book. Get your thoughts down before using your calculator.
  • Make sure your calculator is in good working order and that batteries are fresh. The test center will not have batteries or extra calculators. If your calculator fails during testing and you have no backup, you'll have to complete the test without it.
