A question we get all the time is: “What kind of calculator can I use on the ACT?” If you’re not sure whether or not your calculator is permissible, you better check! If you bring the wrong calculator to the exam, you might be kicked out or your score might be voided. Below, you’ll find a comprehensive list of all BANNED calculators (meaning, if you have this type of calculator, do NOT bring it with you on the official test day).
You may use any 4-function, scientific, or graphing calculator on the ACT as long as it is not on the banned list (below), or as long as it is modified as needed.
Calculators not allowed on the ACT:
|All models beginning with TI-89 or TI-92|
|All models beginning with HP 40G, HP 49G, or HP50G|
|Algebra fx 2.0|
|All models beginning with CFX-9970g|
*TI-Nspire is permitted if not marked CAS
In addition, these calculators permitted with modifications:
|Calculators that can hold programs or documents||Remove all documents and remove all programs that have computer algebra system functionality|
|Calculators with paper tape||Remove tape|
|Calculators that make noise||Turn off sound|
|Calculators with an infrared data port (including HP 38G series, HP 39G series, and HP 48G)||Completely cover the data port with heavy opaque material such as duct tape or electrician’s tape|
|Calculators with power cords||Remove all power/electrical cords|
