ACT Calculator Policy Checker
Check Your Calculator
Use this tool to check if your calculator is likely permitted on the ACT based on its features. Always double-check the official ACT calculator policy.
What is the ACT Calculator Policy?
The ACT calculator policy outlines which types of calculators are permitted and which are prohibited during the mathematics section of the ACT test. Understanding these rules is crucial for test-takers to ensure they bring an approved device and can use it to their advantage. The policy aims to ensure fairness and prevent any student from having an unfair advantage through calculator technology that goes beyond numerical calculations, such as those with Computer Algebra Systems (CAS) or communication capabilities. Anyone taking the ACT math test should be familiar with the latest ACT calculator policy to avoid issues on test day.
Common misconceptions include believing all graphing calculators are banned or that any scientific calculator is fine. While many graphing and scientific calculators are allowed, some specific models and features are strictly forbidden. It’s not just the type, but the specific capabilities that matter when considering **calculators you can use on the ACT**.
ACT Calculator Rules Explained
The ACT has clear guidelines regarding **calculators you can use on the ACT**. Here’s a breakdown:
- Allowed Calculators: Most four-function, scientific, and graphing calculators are permitted.
- Prohibited Features: Calculators are NOT allowed if they have any of the following:
- Computer Algebra System (CAS) – software that performs symbolic manipulation (e.g., solving algebraic equations, factoring, simplifying expressions symbolically).
- QWERTY-style keyboard.
- Wireless, Bluetooth, or infrared communication capabilities.
- Stylus or pen-based input.
- Require an external power source (power cord).
- Have paper tape or make noise.
- Are part of a phone, tablet, laptop, or other electronic device.
- Specifically Prohibited Models: Even without the above features, certain graphing calculator models are banned by name. These include:
- Texas Instruments: All TI-89 and TI-92 models, TI-Nspire CAS (the non-CAS Nspire is allowed).
- Hewlett-Packard: HP 48GII and all HP calculators with CAS (e.g., HP 40G, HP 49G, HP 50G, HP Prime).
- Casio: fx-CP400 (ClassPad 400), ClassPad 300/330, Algebra fx 2.0, CFX-9970G.
It is vital to check the latest official ACT website for the most current list of prohibited calculators ACT before your test date.
Allowed vs. Prohibited Features Summary
| Feature/Type | Allowed on ACT? | Notes |
|---|---|---|
| 4-Function Calculator | Yes | Unless it has other prohibited features (rare). |
| Scientific Calculator | Yes | Unless it has CAS or other prohibited features. |
| Graphing Calculator | Yes (most) | Unless it has CAS, QWERTY, or is on the prohibited model list. |
| Computer Algebra System (CAS) | No | Performs symbolic manipulation. |
| QWERTY Keyboard | No | Looks like a computer keyboard. |
| Wireless Communication | No | Includes Bluetooth, Wi-Fi, Infrared. |
| Stylus/Pen Input | No | Touch screens operated by stylus. |
| Needs Power Cord | No | Must be battery-operated. |
| Makes Noise/Paper Tape | No | Distracting features. |
| Part of Phone/Tablet | No | No smart devices. |
| TI-84 Plus / CE | Yes | Commonly allowed graphing calculator. |
| TI-Nspire (non-CAS) | Yes | The non-CAS version is permitted. |
| TI-89, TI-92, TI-Nspire CAS | No | Specifically prohibited models. |

Practical Examples (Real-World Use Cases)
Let’s look at a few examples of **calculators you can use on the ACT** (or can’t):
- Texas Instruments TI-84 Plus CE:
- Type: Graphing
- CAS: No
- QWERTY: No
- Wireless: No
- On prohibited list: No
- Result: Allowed. This is a very popular and permitted graphing calculator.
- Texas Instruments TI-Nspire CX II CAS:
- Type: Graphing
- CAS: Yes
- QWERTY: No
- Wireless: No (but has CAS)
- On prohibited list: Yes (due to CAS)
- Result: Prohibited. The “CAS” in the name indicates it has a Computer Algebra System.
- Casio fx-115ES PLUS:
- Type: Scientific
- CAS: No
- QWERTY: No
- Wireless: No
- On prohibited list: No
- Result: Allowed. A standard scientific calculator without prohibited features.
- HP Prime:
- Type: Graphing
- CAS: Yes
- QWERTY: No (but has CAS)
- Wireless: No
- On prohibited list: Yes (due to CAS)
- Result: Prohibited. The HP Prime includes CAS functionality.
These examples illustrate how to apply the ACT’s rules to specific **calculators you can use on the ACT** and those you cannot.
How to Use This ACT Calculator Checker
Our checker helps you quickly assess if your calculator is likely one of the **calculators you can use on the ACT**:
- Select Calculator Type: Choose whether your calculator is basic (4-function), scientific, or graphing.
- Check Prohibited Features: Look at your calculator and check the box for any features listed that it possesses (like CAS, QWERTY keyboard, wireless, etc.).
- Enter Specific Model (Optional): Type in the model name (e.g., “TI-84 Plus”). This helps check against the known prohibited list.
- Check Results: The tool will show “Likely Allowed,” “Prohibited,” or “Check Official List.” It will also list the reasons based on your input.
- Read Explanation: The explanation below the results summarizes the general ACT rules applied.
- Always Verify: While this tool is helpful, always consult the official ACT website for the definitive and most up-to-date ACT calculator policy before test day.
The “Copy Results” button allows you to copy the findings for your records or to share.
Key Factors That Affect Calculator Allowance
Several factors determine whether a calculator is among the **calculators you can use on the ACT**:
- Computer Algebra System (CAS): This is a major disqualifier. Calculators that can perform symbolic algebra are banned.
- QWERTY Keyboard: Calculators with typewriter-like keyboards are not allowed.
- Communication Features: Any form of wireless communication (Bluetooth, infrared, Wi-Fi) is prohibited.
- Specific Model Prohibitions: The ACT explicitly bans certain models like the TI-89, TI-92, and TI-Nspire CAS, regardless of other features, often due to their advanced capabilities or CAS.
- Power Source: Calculators needing an electrical outlet are not permitted. They must be battery-operated.
- Other Prohibited Elements: Features like paper tape, sound, or being part of another device (phone, tablet) will get a calculator banned.
- Test Center Discretion (Rare but possible): While the ACT sets the policy, test center supervisors have the final say on the day, although they usually follow the ACT’s guidelines strictly.
Understanding these factors is key to choosing one of the allowed calculators ACT offers.
Frequently Asked Questions (FAQ)
1. Can I use a TI-84 Plus or TI-84 Plus CE on the ACT?
Yes, both the TI-84 Plus and the TI-84 Plus CE are generally allowed on the ACT as they do not have CAS and are not on the prohibited list.
2. Is the TI-Nspire allowed on the ACT?
The TI-Nspire (non-CAS version) is allowed. However, the TI-Nspire CAS is prohibited. Make sure you have the non-CAS model.
3. What happens if I bring a prohibited calculator to the ACT?
If you are found with a prohibited calculator, it will likely be confiscated for the duration of the math test, or you may not be allowed to use any calculator. In some cases, your scores could be invalidated.
4. Can I bring two calculators to the ACT?
You can bring a backup calculator, but only one calculator can be out and in use at any given time during the test.
5. Are all scientific calculators allowed on the ACT?
Most scientific calculators are allowed, but you must ensure they do not have any prohibited features like CAS. Some very advanced scientific calculators might have features that blur the line, so check carefully.
6. Where can I find the official list of calculators you can use on the ACT?
The most up-to-date information is always on the official ACT website (act.org) under their test day policies section. Checking the official list of **calculators you can use on the ACT** is highly recommended.
7. Do I have to clear my calculator’s memory before the ACT?
While the ACT doesn’t explicitly require clearing memory for allowed calculators, it’s a good practice, and some test centers might request it. Programs and data that give an unfair advantage are not allowed.
8. Can I use my phone’s calculator app?
No, phones, smartwatches, and any devices with communication capabilities or that are general-purpose computers are strictly prohibited during the ACT test, including their calculator apps.
