ACT Calculator Policy Checker
The ultimate tool to check your device against the official act calculator policy. Avoid surprises on test day by verifying your calculator model and features right now.
Compliance Verification Tool
Compliance Analysis:
Logic Explained: Our tool uses a logical checklist based on the official act calculator policy. A calculator is marked “PROHIBITED” if it matches any explicitly banned model or feature. It’s marked “REVIEW” if it has features that must be modified (e.g., covering an IR port). Otherwise, it’s considered “ALLOWED”.

What is the ACT Calculator Policy?
The act calculator policy is the official set of regulations from the ACT organization that defines which calculators are permitted for use during the Math Test. Its primary purpose is to maintain a fair and equitable testing environment for all students. By standardizing the available tools, the ACT ensures that the test measures mathematical aptitude, not a student’s ability to operate a powerful computing device. Understanding and adhering to the act calculator policy is a critical part of test preparation.
This policy is for any student planning to take the ACT. A common misconception is that all graphing calculators are forbidden, which is false; many popular models are perfectly acceptable. The rules specifically target calculators with features that could provide an unfair advantage, such as solving algebra problems symbolically or communicating with other devices.
The “Formula” of the ACT Calculator Policy Explained
There isn’t a mathematical formula for the act calculator policy; rather, it’s a logical decision tree based on a series of “if-then” conditions. A calculator’s compliance is determined by checking it against a hierarchy of rules. If a calculator fails any single critical rule, it is deemed prohibited.
The logical steps are:
- Explicit Model Check: Does the model name appear on the official list of prohibited calculators (e.g., TI-89, HP Prime)? If yes, it is prohibited.
- Core Feature Check: Does it have prohibited core features like a Computer Algebra System (CAS) or a QWERTY keyboard? If yes, it is prohibited.
- Conditional Feature Check: Does it have features that are only allowed if modified (e.g., an infrared port, a paper printer)? If yes, it requires review and modification to be compliant.
- Device Type Check: Is the device a general-purpose computer or communication device (e.g., phone, tablet)? If yes, it is prohibited.
If a calculator passes all these checks, it is compliant with the act calculator policy. For further reading, check our guide on SAT calculator rules, as policies can differ between tests.
Key Policy “Variables”
| Variable / Feature | Meaning | Policy Status | Typical Example |
|---|---|---|---|
| CAS | Computer Algebra System | Prohibited | Found in models like the TI-Nspire CAS and HP Prime. |
| QWERTY Keyboard | Typewriter-style letter keys | Prohibited | Rare on calculators, but an immediate disqualifier. |
| Communication | Wireless or IR capability | Prohibited | Phones, smartwatches, or calculators with IR ports. |
| Power Cord | Requires external power | Prohibited | Any device that must be plugged into a wall. |
| Model Series | The specific family/name | Conditional | The TI-84 series is allowed; the TI-89 series is not. The act calculator policy is very specific about this. |
Practical Examples (Real-World Use Cases)
Example 1: The Compliant Student
Maria owns a Casio fx-9750GIII. Before her test, she uses this tool. She enters the model name and confirms it has none of the prohibited features. The tool immediately returns “ALLOWED.” The compliance chart shows 100%. She can now focus on her studies, confident that her calculator meets the act calculator policy and is ready for test day. She also reads our best ACT calculator guide to confirm her choice.
Example 2: The Prohibited Calculator
Leo has a Texas Instruments TI-89 Titanium, a powerful calculator he uses for his advanced physics class. When he checks it using our tool, the result is instant: “PROHIBITED.” The reason given is that the TI-89 series is explicitly banned due to its built-in Computer Algebra System (CAS). Leo now knows he must borrow or purchase a compliant model, like a TI-83 or TI-84, and spend time practicing with it to be prepared.
How to Use This ACT Calculator Policy Tool
Using this calculator is a simple, three-step process to ensure you comply with the act calculator policy.
- Enter Your Model: Start by typing the model name of your calculator into the input field. Be as specific as possible.
- Select Features: Carefully review the checklist of prohibited and restricted features. Check the box next to any feature your calculator possesses.
- Analyze the Results: The tool provides an instant verdict—ALLOWED, PROHIBITED, or REVIEW. Read the details in the “Compliance Analysis” section to understand the specific reasons for the outcome. Use this information to make a final decision.
This streamlined process removes any ambiguity and gives you a definitive answer based on the current act calculator policy. For more help, download our Free ACT Study Guide.
Key Factors That Affect Policy Compliance
Six main factors determine whether a calculator is compliant. Ignoring any of these could put your test score at risk.
- Computer Algebra System (CAS): This is the number one disqualifier. A CAS can perform symbolic algebra, which the ACT tests as a manual skill. Banning it keeps the test fair.
- Communication Capabilities: Any feature that allows a calculator to communicate with other devices (infrared, Bluetooth, Wi-Fi) is strictly forbidden to prevent cheating.
- QWERTY Keyboards: To prevent students from storing notes or typing text, calculators with typewriter-style keyboards are banned from the testing room.
- Explicitly Banned Models: The ACT publishes a list of specific calculator models that are not allowed under any circumstances. This is a core part of the act calculator policy.
- Power Source: The calculator must be battery-powered. For logistical and safety reasons, devices that need to be plugged into a wall are not permitted.
- Required Modifications: Some features are only allowed if modified. For example, a printing calculator is fine if the paper tape is removed, and an IR port is acceptable if covered with opaque tape. This is a nuanced but important part of the act calculator policy.
Frequently Asked Questions (FAQ)
It depends. The standard TI-Nspire CX is allowed. The TI-Nspire CX CAS is explicitly prohibited. You must check that the letters “CAS” do not appear on your calculator’s face.
The Texas Instruments TI-84 Plus family (including the CE version) is overwhelmingly the most popular and widely recommended calculator that is fully compliant with the policy.
The ACT requires you to remove any programs that have CAS functionality or that violate the policy. While proctors may not check every device, you are responsible for ensuring it is compliant. Our ACT math prep course covers these best practices.
Calculators that make any audible sound are not allowed unless the sound feature can be disabled. Ensure your calculator is silent before entering the test center.
Generally, no. Per the act calculator policy, devices with a stylus are prohibited, with a few very specific exceptions for older, discontinued models.
The policy’s strictness is designed to ensure fairness. It guarantees that the ACT Math test is a measure of your mathematical reasoning skills, not your access to advanced technology. It’s a key part of standardized college entrance exams.
No. If a calculator has any prohibited feature (like CAS), it is not allowed, even if its specific model name is not on the banned list. The feature rules override the model list.
You can always find the most current version of the policy on the official ACT website (act.org). Our tool is designed to reflect these rules, but checking the official source is always a good idea.
