Students are allowed to use calculators on the math portion of the ACT, specifically during the second half of the math section, which includes 24 questions where calculator use is permitted
Types of Calculators Allowed
- Any 4-function, scientific, or graphing calculator is allowed as long as it meets ACT guidelines and is not on the prohibited list
- Accessible calculators (audio or Braille) are allowed with prior authorization
- Popular approved models include Texas Instruments TI-83 Plus, TI-84 Plus, TI-84 Plus CE, Casio FX series (such as FX-260, FX-300), and simple scientific calculators like TI-30X and TI-34 series

Summary
You can bring any 4-function, scientific, or graphing calculator that does not have CAS capabilities and is not on the banned list. Ensure your calculator is properly modified if it has features like printing, sound, or infrared ports. Calculators are only allowed on the second half of the ACT math section, and you must bring your own calculator as test centers typically do not provide them
