ACT Permissible Calculators
Calculators are as such not required to take the examination. However the student will be allowed to take it on the mathematics test. It cannot be carried in science examination, else the examination answer sheet won't be considered and will be dismissed. It is the student's duty to initially check if the calculator is functional and bring enough batteries that may be required. Test centers will not provide any backup calculators or batteries.
Among the various calculators that are available in the market, only few types are permissible. Most four-function, scientific or graphing calculators are permitted. However some features may have to be disabled which are not permitted, before the calculator can be used in examination. Calculators within devices such as functions-cell phones, laptops, PDAs-are prohibited in examination hall as they are calculators with built-in algebra capabilities or QWERTY keyboard buttons.
The calculators which are not allowed to be taken in the examination are: All Texas Instruments model numbers that begin with TI-89 and TI-92, the TI-Nspire CAS (the non-CAS TI-Nspire is allowed); the Hewlett-Packard hp 48GII model and all model numbers that begin with hp 40G, hp 49G, or hp 50G; the Casio Algebra fx 2.0, ClassPad 300, and all model numbers that begin with CFX-9970G; and all electronic writing pads or pen-input devices, except for the Sharp EL 9600.
It is vital to remove the paper tape on the calculator, if there, to use it in exam. If the student has a model that makes sounds, disabling the sound feature makes the calculator acceptable for use during the test.
For calculators that can communicate wirelessly, infrared ports must be covered with opaque material (such as electrician's tape or duct tape) of sufficient thickness to block infrared signals. Also, calculators with power cords must have the cords removed before they can be used during the exam.
