Formula Explanation: This tool checks your input against the ACT’s official list of prohibited features and models. The result is based on a “logic formula” that flags calculators with Computer Algebra Systems (CAS), QWERTY keyboards, wireless capabilities, and other banned attributes.

What are ACT Allowable Calculators?

ACT allowable calculators are the specific handheld electronic devices that students are permitted to use during the mathematics section of the ACT test. The ACT organization has a detailed policy designed to ensure fairness and test security. While all math problems on the ACT can be solved without a calculator, using a familiar and permitted device can significantly improve speed and accuracy. Understanding the rules for act allowable calculators is a critical part of test preparation.

This policy affects any student taking the ACT. Bringing a non-compliant calculator can result in it being confiscated, or in the worst case, dismissal from the test and voiding of your score. A common misconception is that any graphing calculator is fine, but many powerful models, especially those with a Computer Algebra System (CAS), are strictly forbidden. Another mistake is assuming a calculator allowed on the SAT is automatically one of the act allowable calculators; policies can differ.

The ACT’s “Formula” for Prohibited Calculators

There isn’t a single mathematical formula, but rather a set of rules or logical conditions that determine which devices are not act allowable calculators. The policy primarily targets features that could provide an unfair advantage. The check involves identifying if a calculator possesses any of these prohibited attributes.

Here’s a step-by-step explanation of the logic used to evaluate calculators:

1. Check for CAS: The system first checks if the model has a Computer Algebra System (CAS), which can perform algebraic manipulations. This is the most common reason for a calculator to be banned.
2. Check for QWERTY Keyboard: It then checks for a typewriter-style (QWERTY) keyboard.
3. Check for Wireless/Communication: Any device with Wi-Fi, Bluetooth, or cellular capability is prohibited. This includes all smartphones, tablets, and smartwatches.
4. Check for Other Prohibited Features: The logic also accounts for other banned features like paper tape, sound, or the need for a power cord.

The successful use of act allowable calculators depends on avoiding models with these features.

Key Prohibited Feature “Variables”

Variable (Feature)	Meaning	Status	Typical Models
CAS (Computer Algebra System)	Can simplify and solve algebraic expressions symbolically.	Prohibited	TI-89, TI-Nspire CAS, HP Prime
QWERTY Keyboard	Has a typewriter-style keyboard for text input.	Prohibited	Older models with text entry features.
Wireless Capability	Can connect to the internet or other devices.	Prohibited	Phones, Tablets, Laptops
Paper Tape	Prints calculations on a roll of paper.	Modification Required	Printing calculators (tape must be removed).
Power Cord Needed	Cannot operate on battery power alone.	Prohibited	Devices that must be plugged in.

Practical Examples of ACT Allowable Calculators

Let’s look at two real-world examples to understand the policy for act allowable calculators in action.

Example 1: A Permitted Calculator

• Input Model: Texas Instruments TI-84 Plus CE
• Analysis:
  • Does it have CAS? No.
  • Does it have a QWERTY keyboard? No.
  • Does it have wireless? No.
• Output: ALLOWED
• Interpretation: The TI-84 Plus CE is one of the most popular and widely recommended act allowable calculators. It provides powerful graphing capabilities without any prohibited features.

Example 2: A Prohibited Calculator

• Input Model: Texas Instruments TI-89 Titanium
• Analysis:
  • Does it have CAS? Yes. The TI-89 has a powerful Computer Algebra System.
• Output: PROHIBITED
• Interpretation: Despite its visual similarity to the TI-84, the TI-89 is banned specifically because its CAS functionality can solve equations algebraically, which violates ACT testing rules. This highlights the importance of checking the exact model when looking for act allowable calculators. See our guide to financial planning for more resources.

3. Review the Result: The tool will display one of three outcomes:
   • ALLOWED: Your calculator is permitted for use on the ACT.
   • PROHIBITED: Your calculator is explicitly banned and cannot be used. The reason will be provided.
   • REVIEW NEEDED/NOT FOUND: The model may have versions with and without prohibited features (like CAS), or it may be an uncommon model. You must verify its features against the official ACT policy. This is a key step in ensuring you have one of the valid act allowable calculators.
4. Decision-Making: If your calculator is prohibited, you must acquire a new one for the test. The investment calculator on our site can help you budget for a new device. If it’s allowed, ensure it has fresh batteries and you are familiar with its functions.

Key Factors That Affect ACT Allowable Calculators

Several key features determine a calculator’s eligibility. Understanding these factors is crucial for selecting from the pool of act allowable calculators.

• Computer Algebra System (CAS): This is the most significant factor. A CAS can perform symbolic algebra, such as factoring, expanding, and solving equations with variables. The ACT prohibits this to ensure students demonstrate their own algebraic skills.
• QWERTY Keyboards: Calculators with typewriter-style keyboards are banned. This is to prevent the storage of notes or the use of unapproved programs. Letter keys in a non-QWERTY format (like an ABC layout) are generally permitted.
• Communication Capabilities: Any device that can communicate wirelessly (e.g., Wi-Fi, Bluetooth, NFC, infrared) is strictly forbidden. This rule prevents cheating and maintains test security. When considering retirement planning, think of this as a strict security measure.
• External Power Source: The calculator must be battery-operated. Models that require an electrical outlet are not allowed in the testing room.
• Noise and Printing: Calculators that make noise must be muted. Those with a paper tape feature are only allowed if the paper tape is removed before the test. These rules for act allowable calculators are to prevent disruptions.
• Pen-Input or Stylus: Most devices that use a stylus or pen-input are prohibited, as they are considered a form of computer. The Sharp EL-9600 is a notable exception to this rule. A proper assessment of act allowable calculators must consider this.

Checking these factors is a core part of confirming you have one of the approved act allowable calculators. For other tools, check out our loan calculator.

Frequently Asked Questions (FAQ)

1. Can I use my phone’s calculator app on the ACT?

No. All phones, smartwatches, tablets, and laptops are strictly prohibited from the testing room. Using one will result in immediate dismissal. Your device must be a dedicated handheld calculator.

2. What’s the difference between the TI-Nspire and the TI-Nspire CAS?

The TI-Nspire (non-CAS version) is an allowed calculator. The TI-Nspire CAS has a Computer Algebra System and is explicitly prohibited. You must check the calculator’s faceplate to see if the letters “CAS” are present. This is a critical distinction for act allowable calculators.

3. What happens if my calculator is not on any official list?

If you can’t find your model on any list, it’s your responsibility to prove it’s an allowable device. This means ensuring it has no prohibited features like CAS, a QWERTY keyboard, or wireless capabilities. When in doubt, it is safest to use a common, explicitly approved model.

4. Are all scientific calculators allowed?

Yes, virtually all standard scientific calculators are allowed. They do not have the advanced graphing or CAS features that are typically prohibited, making them a safe choice among act allowable calculators.

5. Do I need a graphing calculator for the ACT?

No, you do not need one. Every question can be solved without a calculator. However, a graphing calculator can be a powerful tool for solving complex equations, visualizing functions, and saving time, provided you know how to use it efficiently.

6. My calculator has games on it. Is that allowed?

While the ACT policy focuses on CAS and communication, proctors may require you to clear your calculator’s memory, which would delete any programs or games. It is best practice to remove all non-essential programs before test day. A guide to act allowable calculators would always recommend this. Our savings calculator can help you plan for educational expenses.

7. Can I share my calculator with another student?

No. Sharing calculators is strictly forbidden during the test. You should bring your own primary calculator and consider bringing a backup with fresh batteries in case of failure.

8. What is the best ACT allowable calculator to buy?

The “best” calculator is the one you are most comfortable with. However, the TI-84 Plus series (including the CE) is widely considered the standard for a reason: it’s powerful, allowed, and used in many high school math classes. This familiarity makes it a top choice for those seeking reliable act allowable calculators.
