What types of calculators are allowed on the ACT, SAT, and PSAT?

Standardized math tests can be intimidating. Fortunately, students are not entirely on their own when it comes to the math sections of the SAT, PSAT, and ACT. Bringing the right calculator on test day can boost your score by helping you maximize your time and minimize simple computational mistakes.

Before packing your bag, it’s important to understand the College Board’s and ACT’s calculator policies. Here’s a guide to the types of calculators you’re allowed to use on the ACT, SAT, and PSAT.

SAT & PSAT

The SAT and PSAT each include two math sections, and while students are not permitted to use a calculator on the first section, a calculator is permitted on the second section.

Calculators permitted by the College Board must be battery-operated, handheld models. These include:

  • Most graphing calculators
  • All scientific calculators
  • All four-function calculators (not recommended)

Calculators not permitted by the College Board include:

  • Calculators that have a computer-style (QWERTY) keypad or stylus
  • Any laptops, tablets, smartphones, smartwatches, etc.

ACT

Students can use a calculator on the entirety of the math section of the ACT. Any 4-function, scientific, or graphing calculator is permitted as long as it is not on the prohibited list.

Here are the calculators that are not permitted:

  • Calculators with built-in or downloaded computer algebra system functionality, including:
    • Texas Instruments:
      • All model numbers that begin with TI-89 or TI-92
      • TI-Nspire CAS (the non-CAS TI-Nspire is permitted)
    • Hewlett-Packard:
      • HP Prime
      • HP 48GII
      • All model numbers that begin with HP 40G, HP 49G, or HP 50G
    • Casio:
      • fx-CP400 (ClassPad 400)
      • ClassPad 300 or ClassPad 330
      • Algebra fx 2.0
      • All model numbers that begin with CFX-9970G
  • Calculators that have a computer-style (QWERTY) keypad or stylus
  • Any laptops, tablets, smartphones, smartwatches, etc.
