Are TI-84 Calculators Allowed in Exams?

Is a TI-84 allowed in an exam? On the tests that permit a graphing calculator, yes. The digital SAT, the ACT mathematics test, most of the AP exams that allow a calculator and the IB papers that call for a graphic display calculator all accept the TI-84 Plus and the TI-84 Plus CE, as long as the handheld meets the conditions each board places on every permitted model.

The conditions matter more than the brand. Every exam board publishes its own list of prohibited features, and a calculator is judged on what it can do rather than on the name on the case. The TI-84 Plus family sits on the permitted side of each of those lists, which is why it is the handheld most US students already own when they sit down at the desk.

This page maps the position across the four main exam families and links to a detailed page for each. Treat it as a starting point, not as a substitute for the official wording — on every exam, the board’s own document is the version that counts.

How the four exam families treat the TI-84

Read the table as a map rather than as the rule. Each cell points to a policy you should open for yourself, because the detail underneath it is where most mistakes happen.

• SAT calculator policy — where the graphing calculator is allowed on the digital SAT, and the on-screen calculator inside Bluebook.
• ACT calculator policy — the mathematics test only, and what has to stay off the desk for the other tests.
• AP calculator policy — which AP exams allow a graphing calculator and which allow only a four-function model.
• IB calculator policy — the graphic display calculator, and why the answer depends on your subject and school.

The prohibitions the boards share

The four families differ in where they allow a calculator, but they draw on a similar list of features that will get a handheld turned away. The wording differs between boards; the themes repeat.

• A computer algebra system (CAS). A CAS manipulates symbols algebraically — it can rearrange an expression the way you would on paper, not merely evaluate it. This is the single most common feature on a prohibited list, and it is why a model that solves equations symbolically can be refused while a numeric graphing calculator is accepted.
• A QWERTY keyboard. A full letter layout suggests text entry, note storage or typed communication, which boards exclude. A calculator keypad is designed for numbers and functions, not for typing prose.
• Wireless or internet capability. A device that can connect to a network could send or receive help mid-exam, so connectivity is treated as disqualifying.
• Recording or communication ability. Phones, smart watches and cameras are not permitted in the testing room, and a calculator that can photograph, record or transmit belongs in the same category. A dedicated handheld has none of these functions.

Because the lists overlap, a calculator that fails one board usually fails all of them. It is not really a question of which exam you are sitting — it is a question of what the machine is capable of.

Why the TI-84 Plus and TI-84 Plus CE clear every check

The TI-84 Plus and the TI-84 Plus CE are graphing calculators, not computer algebra systems. They evaluate numbers and draw graphs accurately, but they do not rearrange algebraic symbols in the way a CAS does. That one difference is what keeps them on the permitted lists for the SAT, the ACT and AP Calculus.

Work through the shared prohibitions one at a time and the position is clear. The keypad is a calculator keypad rather than a QWERTY layout. There is no wireless or internet connection. There is no camera, microphone or recorder, so it cannot capture or transmit anything. The TI-84 Plus CE adds a colour screen, but that changes the display, not the category: it remains a numeric graphing calculator.

One caveat is worth stating plainly. TI sells other graphing models as well, and some of those carry CAS capability. If you are choosing a handheld specifically for exams, check the board’s permitted list against the exact model on the box before you buy, rather than assuming that any TI graphing calculator qualifies.

What to check before test day

Four checks cover almost everything students get caught by, and none of them takes long.

• Confirm the rule. Open the board’s policy page for your exam and read the prohibited list. Do this once when you book the test and again in the week before, because wording is revised occasionally.
• Ask about memory. There is no public clearing rule for the SAT, ACT or AP. Some IB schools require memory to be cleared or a particular mode, so ask your teacher or coordinator what your centre expects. If you are told to reset, our guide to resetting a TI-84 to factory defaults walks through the steps safely.
• Check the mode and the batteries. Set the calculator to the mode your subject uses and put fresh batteries in, or charge the CE. A handheld that dies mid-test cannot be replaced from a drawer.
• Practise with the same handheld. Rehearse the operations you rely on, such as graphing a function, so that you are not discovering the keystrokes under time pressure. A stray ERR: SYNTAX costs time even when the calculator is permitted; see our ERR: SYNTAX fix if the message keeps appearing.

When the official document wins

Everything on this page is written to help you find the official rule quickly. It is not the rule itself. The College Board, ACT and the IB each publish their own policy, revise it from time to time, and expect you to follow the version in force for your sitting.

If your teacher, invigilator or IB coordinator tells you something different from what you have read here, follow them and then open the official document to confirm. If this page and an official policy ever disagree, the official policy wins. That is the safest habit to carry into any exam room.
