What is the ACT Calculator Policy?
The ACT calculator policy outlines the rules for using a calculator on the ACT math section. The purpose is to ensure fairness for all test-takers and prevent any unfair advantages. While you are allowed to use a calculator on the entire math test, not all calculators are permitted. The fundamental rule is that any four-function, scientific, or graphing calculator is allowed as long as it’s not on the prohibited list. Knowing whether your device is acceptable before test day is critical to avoid issues. Answering the question “can you use a calculator on the act math sectino” is simple: yes, but with important restrictions.
Common misunderstandings often involve Computer Algebra Systems (CAS). A calculator might look standard, but if it has a CAS, which can solve algebraic equations symbolically, it’s banned. This is because such features undermine the skills the test is designed to measure.
The ACT’s Prohibited Features “Formula”
Instead of a mathematical formula, the ACT policy is a set of logical rules. A calculator is deemed **PROHIBITED** if it has one or more of the following features. This is the core logic our can you use a calculator on the act math sectino checker uses. For more details on specific models, consider reviewing the official ACT policy.
| Variable (Feature) | Meaning | Unit / Type | Status if Present |
|---|---|---|---|
| CAS | Computer Algebra System | Boolean (Yes/No) | Prohibited |
| QWERTY Keyboard | Typewriter-style letter keys | Boolean (Yes/No) | Prohibited |
| Communication Device | Part of a phone, tablet, laptop | Boolean (Yes/No) | Prohibited |
| Power Cord | Requires external power source | Boolean (Yes/No) | Prohibited |
| Audible Noise / Paper Tape | Makes sound or has a printer | Boolean (Yes/No) | Prohibited (unless modified) |
Practical Examples
Example 1: The TI-84 Plus
- Inputs: No CAS, not a communication device, no QWERTY keyboard, battery-powered.
- Result: LIKELY PERMITTED
- Reasoning: The TI-84 Plus is one of the most common and widely accepted graphing calculators for the ACT. It meets all the necessary criteria.
Example 2: The TI-89 Titanium
- Inputs: Has a Computer Algebra System (CAS).
- Result: PROHIBITED
- Reasoning: The TI-89 is explicitly banned because its CAS functionality allows it to perform algebraic manipulations that students are meant to do by hand. This is a key example for anyone researching can you use a calculator on the act math sectino.

Key Factors That Affect Calculator Permission
Several key features determine if a calculator is allowed. Understanding these will help you choose the right tool for test day.
- Computer Algebra System (CAS): This is the most common reason for a graphing calculator to be banned. CAS can perform symbolic algebra, which is against the rules.
- QWERTY Keyboards: Any calculator with a keyboard in the standard QWERTY layout is prohibited.
- Communication Capabilities: Devices like phones, tablets, and smartwatches are strictly forbidden.
- Power Source: Calculators that need to be plugged into an electrical outlet are not allowed.
- Noise and Paper Tape: If your calculator makes noise or has a paper tape printer, the sound must be turned off and the tape removed.
- Programs and Documents: You may be required to clear your calculator’s memory of any programs or documents before the test.
Frequently Asked Questions (FAQ)
1. Can you use a calculator on the entire ACT math section?
Yes, the current ACT policy permits the use of an approved calculator on all 60 questions of the math test.
2. What happens if I bring a prohibited calculator?
A test proctor will check your calculator. If it’s on the prohibited list, you will not be allowed to use it. You may be dismissed from the test.
3. Is a TI-Nspire allowed?
It depends. The TI-Nspire CX (non-CAS) is permitted, but the TI-Nspire CX CAS is prohibited. You must check the specific model.
4. Do I need to clear my calculator’s memory?
Yes, the ACT requires that you remove any programs with CAS functionality. It’s a good practice to clear all non-essential programs and documents. If you’re wondering can you use a calculator on the act math sectino with games, the answer is no; they must be removed.
5. Can I use my phone’s calculator?
No. All devices with communication capabilities, including phones, are strictly prohibited.
6. What is the best approved calculator to use?
Models like the TI-84 Plus series are very popular and widely recommended because they offer advanced graphing capabilities without having a prohibited CAS. For further guidance, check out TI’s approved list.
7. Are calculators allowed on the ACT Science section?
No, calculators are only permitted on the mathematics test.
8. What if my calculator has an infrared data port?
You must completely cover the port with opaque material like duct tape or electrician’s tape for it to be permitted.
