What is the ACT Calculator Policy?
The question, "Are graphing calculators allowed on the ACT?", is one of the most common inquiries among students preparing for the exam. The ACT (American College Testing) has a strict policy regarding the use of calculators during the Math section. This policy is designed to ensure fairness and prevent any unfair advantages. Essentially, while many graphing calculators are allowed, certain features and models are explicitly prohibited. Understanding these rules is crucial to avoid having your calculator confiscated or even being dismissed from the test.
This policy checker is designed for anyone taking the ACT, particularly those who plan to use a graphing calculator. It helps clarify common misunderstandings, especially regarding advanced features like Computer Algebra Systems (CAS) or wireless capabilities, which are often the cause of disallowance.
ACT Calculator Eligibility Rules and Explanation
The ACT calculator policy isn't a single formula but a set of conditions that determine a calculator's eligibility. There are no "units" in the traditional sense, but rather "feature units" that are either present or absent. The overall eligibility is a boolean (true/false) outcome based on these conditions.
Eligibility Logic (Not a Formula, but a Rule Set):
A calculator is **ALLOWED** if and only if:
- It is not explicitly identified as a prohibited type (e.g., phone, laptop, calculator with paper tape).
- It does NOT possess any of the following prohibited features:
- QWERTY (typewriter-like) keyboards.
- Computer Algebra System (CAS) capability (for most tests, some specific models might have nuances).
- Wireless communication (Bluetooth, Wi-Fi, cellular, infrared).
- Internet access.
- Cameras or scanning devices.
- Pen input or stylus functionality.
- Ability to make noise or has audio/video recording/playback.
- Requires an electrical outlet.
- Has a paper tape.
- It is not a specific model explicitly banned by the ACT.
If any of these conditions are not met (i.e., it's a prohibited type or has a prohibited feature), the calculator is **NOT ALLOWED**.

Practical Examples of ACT Calculator Eligibility
Example 1: The Popular TI-84 Plus CE
- Inputs:
- Calculator Type: Graphing Calculator
- Specific Model: TI-84 Plus CE
- Prohibited Features: All unchecked (as the TI-84 Plus CE does not have QWERTY, CAS, wireless, etc.)
- Result: ALLOWED
- Explanation: The TI-84 Plus CE is one of the most commonly used and widely accepted graphing calculators for the ACT. It lacks any of the features explicitly prohibited by the ACT policy, making it a safe choice.
Example 2: A Graphing Calculator with CAS
- Inputs:
- Calculator Type: Graphing Calculator
- Specific Model: TI-Nspire CX CAS (or leave blank and check 'Computer Algebra System (CAS)')
- Prohibited Features: 'Computer Algebra System (CAS)' checked
- Result: NOT ALLOWED
- Explanation: Calculators with Computer Algebra System (CAS) functionality are generally prohibited on the ACT because they can perform symbolic manipulation (like solving equations algebraically) that is beyond the scope of what's allowed. Even if the calculator has no other prohibited features, CAS alone is enough to disqualify it.
Example 3: A Scientific Calculator with No Prohibited Features
- Inputs:
- Calculator Type: Scientific Calculator
- Specific Model: Not applicable
- Prohibited Features: All unchecked
- Result: ALLOWED
- Explanation: Most standard scientific calculators are perfectly fine for the ACT. They provide the necessary arithmetic and trigonometric functions without any of the advanced, prohibited features found in some graphing models.

Key Factors That Affect Whether Graphing Calculators Are Allowed on the ACT
The ACT's primary concern with calculators is to prevent any device from giving a student an unfair advantage or from being used for purposes other than legitimate mathematical calculations. Here are the key factors:
- QWERTY Keyboards: Any calculator with a typewriter-style (QWERTY) keyboard is strictly prohibited. This is to prevent students from typing out notes or communicating.
- Computer Algebra System (CAS): Calculators with CAS functionality are generally not allowed. CAS can perform symbolic manipulation, such as solving equations algebraically, factoring polynomials, or finding derivatives/integrals, which the ACT considers an unfair advantage. Examples include TI-Nspire CX CAS, HP Prime (if CAS is enabled), and Casio ClassPad series.
- Wireless Communication: Features like Bluetooth, Wi-Fi, cellular, or infrared communication are prohibited. This is to prevent any form of external communication or data transfer during the test.
- Internet Access: Any device capable of accessing the internet is banned. This includes smart devices, phones, or graphing calculators with built-in internet.
- Cameras or Scanners: Calculators with built-in cameras, scanning devices, or any photographic capabilities are not allowed to prevent illicit recording of test materials.
- Pen Input/Stylus: Devices that require or support a pen or stylus for input (other than basic touch screen navigation, if applicable to allowed models) are often prohibited, as they can facilitate note-taking or cheating.
- Noise and Multimedia: Calculators that can make noise, record audio/video, or play multimedia are disallowed to maintain a quiet testing environment and prevent distractions or cheating.
- External Power/Paper Tape: Calculators requiring an electrical outlet or those that produce a paper tape are also on the prohibited list, mainly due to logistical issues in a testing environment.
Understanding these factors is vital. Even if a calculator is a "graphing calculator," the presence of just one of these features can render it unsuitable for test day.

Frequently Asked Questions (FAQ) about ACT Calculator Policy
Q1: Are all graphing calculators prohibited on the ACT?
A: No, not all graphing calculators are prohibited. Many popular models, like the TI-84 Plus CE, are perfectly acceptable. The prohibition applies to specific features (e.g., QWERTY keyboards, CAS, wireless communication) rather than the category of "graphing calculator" itself.
Q2: What's the main difference between an allowed and a prohibited graphing calculator?
A: The main difference lies in prohibited features. An allowed graphing calculator will perform standard arithmetic, graphing, and basic scientific functions without having a QWERTY keyboard, CAS, wireless communication, internet access, camera, or pen input. Prohibited calculators will possess one or more of these features.
Q3: Can I use a calculator with a touch screen?
A: Some touch-screen graphing calculators are allowed, provided they do not have a QWERTY keyboard, pen input, wireless communication, internet access, or CAS. For example, some versions of the TI-Nspire CX (non-CAS) are touch-enabled and allowed.
Q4: My calculator has a CAS function, but I can disable it. Is it allowed?
A: The ACT policy states that any calculator with a CAS (Computer Algebra System) is prohibited. Even if you can disable the function, the *presence* of the capability often makes it disallowed. It's best to err on the side of caution and use a non-CAS calculator.
Q5: Do I need to clear my calculator's memory before the ACT?
A: Yes, it is highly recommended to clear the memory of your graphing calculator before the test. While not explicitly part of the "allowed" policy, test proctors may require it, and it prevents any suspicion of stored notes or formulas.
Q6: Are scientific calculators always allowed?
A: Most standard scientific calculators are allowed as they typically lack the advanced features that are prohibited on graphing calculators. However, always double-check that your scientific calculator doesn't have any unusual features like internet connectivity or QWERTY keyboard (which is rare for scientific calculators).
Q7: What if my calculator is not on the specific model list?
A: If your calculator isn't on a specific "allowed" or "prohibited" list (which the ACT doesn't publish exhaustively), you must manually check for the prohibited features listed in the policy. Our calculator tool helps you do exactly that by asking about specific features.
Q8: What happens if I bring a prohibited calculator?
A: If you bring a prohibited calculator, it will be confiscated by the test proctor, and you will not be allowed to use any calculator for the Math section. In severe cases (e.g., attempting to use a phone), you could be dismissed from the test center and have your scores canceled. It's always better to bring a backup calculator if you're unsure.
