Yes, but only the one built into the exam. A basic calculator is part of the ATI TEAS® exam and opens on screen from the calculator icon next to the timer. It is available on every question in every section, not just math. Do not bring your own: personal calculators, phone calculators, and calculator watches are not allowed for any TEAS exam, at home or in person.
Get to know the calculator before test day. The on-screen calculator works differently from a handheld one, and fumbling with it under a timer costs points. Take the free ATI TEAS practice test to try it, then use the ATI TEAS Online Practice Tests to practice full timed math sections with it. Both use the exact calculator you will see on the real exam.
Frequently asked questions
What kind of calculator is it?
A basic calculator: addition, subtraction, multiplication, and division, plus percent, square root, a decimal point, a backspace key, and memory keys (m+, m-, mrc, mc). It is not a scientific or graphing calculator, and the math section is written with that in mind.
Which sections have the calculator?
All of them. The calculator icon stays on screen for the whole exam. You will use it most in the math section, but some science questions and the occasional English and language usage question call for a quick calculation too.
How do I open it during the exam?
Click the calculator icon at the upper right of the question screen, next to Time Remaining. It opens in a window you can move around the screen and close when you are done. The practice tests show you exactly where it is.

The on-screen calculator
Can I use scratch paper for calculations?
Yes. You may have one blank sheet of paper (or a small dry-erase whiteboard) and two writing instruments. Scratch paper rules
What if I am taking a paper-and-pencil TEAS?
Very few schools still use the paper version. If yours does, the proctor hands out a calculator; you still may not bring your own.
What if I bring a calculator anyway?
At a testing site it must stay outside the exam room with your other personal items. During a remote exam, a calculator in view of the camera can be flagged as an irregularity.
