Students may use a basic four-function, scientific, or graphing calculator that follows ACT rules. Battery powered only, no communication features, no external keyboards, and sound off. In the online ACT, an on-screen calculator is available, but students may still use a permitted handheld if they prefer. Train with the exact model they will bring to reduce test-day friction.

CAS rules and prohibited devices
An act cas calculator is not allowed. If a calculator includes a computer algebra system, QWERTY keyboard, wireless or Bluetooth communication, camera, audio, or app capability, it is prohibited. A CAS model is not acceptable even if CAS is disabled. Phones, tablets, laptops, and watch calculators are banned. If a device is rejected at check-in, the student must test without it, so teach a no-calc fallback.
If students are comparing policies, share this explainer: ACT vs SAT.

In the online ACT, an on-screen calculator is available in Math. Students may still use a permitted handheld. Coach when to prefer each tool: quick arithmetic on handheld, multi-step problems on the on-screen calc with clean history. Rehearse keyboard entry, fraction formats, and error-checking. Build mixed sets with calculator and no-calculator items to strengthen number sense and speed.
