Policy Logic: Calculators are generally permitted on the ACT if they do not have features that could compromise test integrity. This includes graphing, QWERTY keyboards, network connectivity, CAS, and speech/writing capabilities. Scientific calculators without these advanced, problematic features are allowed. ACT explicitly prohibits “electronic devices with memory, writing capability, or calculators that have computer algebra system functions”. Graphing and scientific calculators are allowed only if they meet specific criteria.

Permitted Calculator Features on the ACT

The ACT calculator policy is designed to ensure a fair testing environment. While many calculators are allowed, certain features are strictly prohibited to prevent cheating. Understanding these rules is vital for every ACT test-taker. This section breaks down the core criteria.

Key Permitted Calculator Types:

Basic Calculators: Simple four-function, solar, and battery-powered calculators are always acceptable.
Standard Scientific Calculators: Most standard scientific calculators, like the TI-30 or Casio fx-115 series, are permitted as they lack prohibited features.
Graphing Calculators (with Restrictions): Certain graphing calculators are allowed if they meet specific criteria and do not possess prohibited functions (like CAS or communication capabilities).

Prohibited Calculator Features:

QWERTY Keyboards: Calculators with full alphabetical keyboards are not allowed.
Computer Algebra System (CAS): Devices capable of symbolic manipulation or solving equations algebraically are banned.
Network/Internet Connectivity: Any calculator that can connect to a network, the internet, or communicate wirelessly/via cable is forbidden.
Power Writing/Speech Output: Features that enable text generation or spoken output are prohibited.
Data Stored/Transmitted: Calculators that can store or transmit data, formulas, or notes beyond basic function recall are not permitted.

The ACT aims to allow calculators that aid in computation but do not provide an unfair advantage in terms of accessing external information or performing advanced symbolic tasks.

ACT Calculator Policy Details & Examples

The ACT’s stance on calculators is straightforward: they want tools that assist with mathematical operations but do not offer capabilities that could be used for external assistance or advanced problem-solving beyond the scope of the test’s intended difficulty. A standard scientific calculator is a prime example of a permitted device.

When is a Scientific Calculator Allowed?

A scientific calculator is generally allowed on the ACT if it meets the following conditions:

It does not have a QWERTY keyboard.
It does not have a Computer Algebra System (CAS).
It cannot connect to any wireless networks or the internet.
It does not have speech-output or power-writing features.

Essentially, if your scientific calculator performs standard mathematical functions (trigonometry, logarithms, exponents, roots, etc.) without possessing advanced computing or communication abilities, it is very likely permitted.

Examples of Permitted Scientific Calculators:

Texas Instruments TI-30XIIS
Casio fx-115ES PLUS
Sharp EL-531X

Examples of Prohibited Calculators:

Calculators with full QWERTY keyboards (e.g., some HP models)
Calculators with CAS functionality (e.g., TI-Nspire CX CAS, certain Casio models)
Smartphones, tablets, and other electronic devices with calculator apps that have broader capabilities.

Always check the official ACT website for the most current and detailed calculator policy. The ACT reserves the right to prohibit any calculator deemed inappropriate.

How to Use the ACT Calculator Policy Checker

Our tool is designed to give you a quick and clear assessment of your calculator’s eligibility for the ACT. Follow these simple steps:

Enter Calculator Model: Type the exact name of your calculator model into the “Calculator Model Name” field. Be as precise as possible (e.g., “Texas Instruments TI-84 Plus” not just “TI-84”).
Answer Feature Questions: For each question about calculator features (graphing, QWERTY, CAS, etc.), select the option that accurately describes your device. If you’re unsure, consult your calculator’s manual or manufacturer’s website.
Click “Check Calculator Policy”: Press the button to run the assessment.
Review Results: The “Policy Assessment” section will display a clear verdict: “Allowed,” “Likely Allowed,” “Likely Prohibited,” or “Prohibited,” along with a breakdown of why based on the features you indicated. The intermediate values provide a quick look at each specific rule.
Use “Reset”: If you want to check a different calculator or start over, click the “Reset” button.
Use “Copy Results”: To save or share the assessment, click “Copy Results.” This will copy the main verdict and the intermediate rule checks.

Interpreting the Results: A green “Allowed” status means your calculator is permitted based on the standard ACT policy. Any other status indicates potential issues, and you should double-check the official ACT guidelines or consider bringing a simpler, confirmed-acceptable calculator to be safe.

Frequently Asked Questions (FAQ) About ACT Calculators

Can I use a TI-84 Plus on the ACT?

Yes, the TI-84 Plus (and its common variants like TI-84 Plus Silver Edition) is generally permitted on the ACT, provided it does not have CAS capabilities or unauthorized programs installed. It is a graphing calculator but lacks features explicitly banned by the ACT.

Is the Casio fx-991EX allowed on the ACT?

The Casio fx-991EX is a powerful scientific calculator. It is generally permitted on the ACT as it lacks a QWERTY keyboard, CAS, and network connectivity. Always ensure no advanced add-ins or programs that violate the policy are loaded.

What if my calculator model isn’t listed on the ACT website?

If your specific model isn’t mentioned, assess its features against the ACT’s prohibited list. If it’s a standard scientific calculator with no advanced computing or communication functions, it’s likely allowed. For complex calculators, err on the side of caution and bring a simpler model or contact ACT directly.

Can I use a calculator app on my phone?

No. Electronic devices that can connect to the internet or perform functions beyond basic calculation (like smartphones, tablets, smartwatches) are strictly prohibited during the ACT.

What should I do if my calculator is prohibited?

You should plan to bring an approved calculator to the ACT. Simple scientific calculators like the TI-30XIIS or Casio fx-115ES PLUS are safe choices. ACT provides a limited number of basic calculators at testing sites, but relying on this is not recommended.

Are there any exceptions to the calculator rules?

The ACT policy is quite strict. The only common exception is for students requiring specific assistive technology calculators as an approved accommodation, which must be arranged with ACT beforehand.

Can I use a programmable calculator?

Programmable calculators are generally prohibited if their programming capabilities extend to storing extensive notes, formulas, or using advanced functions that mimic CAS. Standard scientific calculators that allow basic formula recall might be acceptable, but advanced programming is risky.

Will ACT staff check my calculator?

Yes, ACT proctors have the authority to inspect any calculator before the test. If a calculator is deemed non-compliant, you will be required to put it away, and you may not be allowed to use it for the exam.
