What is What Calculators Can I Use on the ACT?

Understanding what calculators can I use on the ACT is a critical step for any student preparing for the exam. The ACT (American College Testing) is a standardized test used for college admissions in the United States. The math section of the ACT allows calculator use, but with strict guidelines. These guidelines are in place to ensure fairness for all test-takers and to prevent the use of devices that could provide an unfair advantage, such as those with advanced computational capabilities or communication features.

The question of what calculators can I use on the ACT isn’t just about having a calculator; it’s about having the RIGHT calculator. Bringing a disallowed calculator can lead to its confiscation, or even dismissal from the test center, causing unnecessary stress and potentially impacting your score. Our tool helps you quickly verify your calculator’s compliance.

Who Should Use This Information?

All ACT Test-Takers: Every student planning to take the ACT should review the calculator policy.
Parents and Educators: To guide students in selecting appropriate calculators for the exam.
Test Prep Centers: To ensure their students are fully prepared for test day regulations.

Common Misconceptions About ACT Calculator Policy

Many students have misconceptions about what calculators can I use on the ACT:

“All graphing calculators are allowed.” This is false. While many graphing calculators are permitted, those with Computer Algebra System (CAS) functionality or QWERTY keyboards are strictly prohibited.
“Basic four-function calculators are too simple.” While not ideal for all problems, basic calculators are allowed and can be sufficient for some questions. The policy doesn’t restrict by simplicity, but by advanced features.
“I can use my phone’s calculator app.” Absolutely not. Cell phones, smartwatches, tablets, and laptops are never allowed as calculators.
“I can bring two calculators as a backup.” While some test centers might allow a backup, it’s generally safer to bring one approved calculator and ensure it has fresh batteries. Check with your specific test center if you plan to bring a backup.

What Calculators Can I Use on the ACT? Formula and Mathematical Explanation

The “formula” for determining what calculators can I use on the ACT isn’t a mathematical equation, but rather a set of logical rules and criteria based on the ACT’s official policy. Our calculator tool applies these rules to your input to provide an eligibility status. The core principle is to identify features that could give an unfair advantage or disrupt the testing environment.

Step-by-Step Derivation of Eligibility Logic:

Check for QWERTY Keyboard: If the calculator has a QWERTY (typewriter-style) keyboard, it is disallowed.
Check for Computer Algebra System (CAS): If the calculator has CAS functionality (e.g., symbolic differentiation/integration, solving equations with variables), it is disallowed.
Check for Wireless Communication: If the calculator can communicate wirelessly (Bluetooth, Wi-Fi, infrared, etc.), it is disallowed.
Check for Paper Tape/Noise: If the calculator prints paper tape or makes noise, it is disallowed.
Check for Internet Access: If the calculator can access the internet, it is disallowed.
Check for Device Type: If the device is a phone, tablet, smartwatch, laptop, or similar general-purpose computing device, it is disallowed.
Final Determination: If any of the above conditions are met, the calculator is “Not Allowed.” Otherwise, it is “Allowed” (assuming no other specific model-based restrictions apply, which are rare for non-prohibited features).

Variable Explanations and Criteria Table:

The “variables” in this context are the specific features of a calculator that the ACT policy scrutinizes. Understanding these helps clarify what calculators can I use on the ACT.

Key Calculator Features and ACT Eligibility Impact
Variable (Feature)	Meaning	Unit	ACT Eligibility Impact
QWERTY Keyboard	A keyboard layout similar to a typewriter, used for text entry.	Boolean (Yes/No)	Disallowed if present.
Computer Algebra System (CAS)	Advanced functionality for symbolic manipulation (e.g., solving equations with variables, symbolic calculus).	Boolean (Yes/No)	Disallowed if present.
Wireless Communication	Ability to send/receive data wirelessly (Bluetooth, Wi-Fi, infrared).	Boolean (Yes/No)	Disallowed if present.
Paper Tape/Noise	Features that print results on paper or produce audible sounds.	Boolean (Yes/No)	Disallowed if present.
Internet Access	Ability to connect to the internet for browsing or data transfer.	Boolean (Yes/No)	Disallowed if present.
Device Type	Whether the device is primarily a phone, tablet, smartwatch, laptop, etc.	Boolean (Yes/No)	Disallowed if it’s one of these general-purpose devices.
Pre-stored Programs/Notes	User-defined programs or notes stored in the calculator’s memory.	Boolean (Yes/No)	Generally allowed, but specific programs giving unfair advantage are disallowed. Test proctors may clear memory.

Practical Examples: What Calculators Can I Use on the ACT?

To further clarify what calculators can I use on the ACT, let’s look at some real-world examples of popular calculator models and their eligibility status.

Example 1: Texas Instruments TI-84 Plus CE (Allowed)

The TI-84 Plus CE is one of the most commonly used and recommended calculators for the ACT. Let’s see why:

QWERTY Keyboard: No
CAS Functionality: No
Wireless Communication: No (though some models have USB for computer connection, not wireless for other devices during test)
Paper Tape/Noise: No
Internet Access: No
Device Type: Dedicated graphing calculator, not a phone/tablet.

Output: Allowed. The TI-84 Plus CE meets all ACT requirements and is a reliable choice for the math section.

Example 2: Texas Instruments TI-89 Titanium (Disallowed)

The TI-89 Titanium is a powerful graphing calculator, but it’s explicitly disallowed by the ACT.

QWERTY Keyboard: No (it has an alpha keyboard, but not QWERTY)
CAS Functionality: Yes (This is the primary reason for disqualification)
Wireless Communication: No
Paper Tape/Noise: No
Internet Access: No
Device Type: Dedicated graphing calculator.

Output: Not Allowed. The presence of CAS functionality makes the TI-89 Titanium ineligible for the ACT. This highlights the importance of checking specific features beyond just the brand or general type of calculator when asking what calculators can I use on the ACT.

Example 3: Casio fx-9750GII (Allowed)

The Casio fx-9750GII is another popular graphing calculator that is generally allowed on the ACT.

QWERTY Keyboard: No
CAS Functionality: No
Wireless Communication: No
Paper Tape/Noise: No
Internet Access: No
Device Type: Dedicated graphing calculator.

Output: Allowed. Similar to the TI-84 Plus CE, this Casio model lacks the prohibited features, making it a suitable option for the ACT.

Key Factors That Affect What Calculators Can I Use on the ACT? Results

Understanding the specific features that influence what calculators can I use on the ACT is crucial for test preparation. The ACT’s policy is designed to create a level playing field, and certain functionalities are deemed to provide an unfair advantage or cause disruption.

Computer Algebra System (CAS) Functionality: This is perhaps the most significant disqualifier. CAS calculators can perform symbolic manipulation, such as solving equations with variables, performing symbolic differentiation or integration, and simplifying algebraic expressions. This capability goes beyond numerical computation and could allow students to bypass understanding fundamental mathematical concepts, hence why they are disallowed. Examples include the TI-89, TI-92, Voyage 200, HP 48GII, and Casio ClassPad series.
QWERTY Keyboards: Calculators equipped with a QWERTY (typewriter-style) keyboard are prohibited. The ACT views these as devices that could be used for storing extensive notes or communicating, rather than purely for mathematical calculations. Even if the keyboard is small, if it’s arranged in a QWERTY layout, it’s generally not allowed.
Wireless Communication Capabilities: Any calculator that can communicate wirelessly (via Bluetooth, Wi-Fi, infrared, or other means) with other devices, such as other calculators, cell phones, or computers, is strictly forbidden. This rule prevents cheating or unauthorized information exchange during the exam.
Internet Access: Devices that can connect to the internet are explicitly disallowed. This includes any calculator with built-in web browsing capabilities, as it could provide access to external resources during the test.
Paper Tape and Noise-Making Features: Calculators that print paper tape or make any audible noise are prohibited. These features can be distracting to other test-takers and disrupt the quiet testing environment.
General-Purpose Computing Devices: The ACT policy clearly states that cell phones, smartphones, smartwatches, tablets, laptops, handheld computers, electronic writing pads, or devices with a pen input are not allowed. These are considered general-purpose computing devices, not dedicated calculators, and pose significant security risks.
Pre-stored Programs and Notes (with caveats): While many allowed graphing calculators can store programs, the ACT reserves the right to disallow any calculator with “pre-stored notes or programs that provide an unfair advantage.” Test proctors may inspect calculators and, in some cases, may require clearing the memory. It’s best to clear any potentially problematic programs or notes before test day.

Frequently Asked Questions (FAQ) About What Calculators Can I Use on the ACT?

Q: Can I use a TI-Nspire CX II CAS on the ACT?

A: No, the TI-Nspire CX II CAS model is NOT allowed because it has Computer Algebra System (CAS) functionality. Only the non-CAS versions of the TI-Nspire CX II (e.g., TI-Nspire CX II) are permitted. Always check for the “CAS” designation in the model name.

Q: What if my calculator has an alpha keyboard, but not a QWERTY keyboard?

A: Most standard graphing calculators have an alpha keyboard for variable input, which is generally allowed. The restriction specifically targets QWERTY (typewriter-style) keyboards. If your calculator’s alpha keys are not arranged like a computer keyboard, it’s likely fine.
