# Use of Calculators on the CAAP Mathematics Test

ACT permits examinees to use a calculator on the CAAP Mathematics Test, but not on any of the other tests. However, all problems on the test can be solved without using a calculator. You may use any four-function, scientific, or graphing calculator, unless it has features described in the Prohibited Calculators list.

Examinees are responsible for ensuring their calculators are permitted.

- calculators built into cell phones or any other electronic communication devices.
- calculators with a typewriter keypad (letter keys in QWERTY format)—Calculators with letter keys not in QWERTY format are permitted.
- calculators with built-in computer algebra systems—Prohibited calculators in this category include:
- Casio:

- calculators with an infrared data port—Completely cover the infrared data port with heavy opaque material such as duct tape or electricianâ€™s tape.
- calculators that have power cords—Remove all power/electrical cords.

Some calculators may have mathematical formulas printed on the calculator itself; these calculators are permitted. Likewise, some calculators come with preprinted instructions for the use of the calculator that are inserted into the calculator cover and carried with it; these instructions do not need to be removed.

Examinees must not share calculators. No examinee may use more than one calculator at a time.
