The ability to use a calculator during the ACT Mathematics section is permitted, with certain restrictions. Not all calculator models are allowed; specifically, devices with computer algebra systems (CAS), those that can communicate wirelessly, or those that have paper tapes are prohibited. Examinees should consult the official ACT website or test preparation materials for a comprehensive list of acceptable and unacceptable calculator models.
Permitting calculator use aims to assess mathematical reasoning skills rather than rote calculation ability. This policy has evolved over time, reflecting changes in technology and educational priorities. Students can leverage allowed calculators to solve complex problems more efficiently, allowing them to focus on conceptual understanding and problem-solving strategies. This support is intended to level the playing field, ensuring students aren’t disadvantaged by the complexity of calculations that could be easily performed by a machine.
