Can You Use 2 Calculators On The Act

The short answer is no, you cannot use two calculators at the same time. However, the official policy allows you to bring a backup. Use our interactive checker below to see if your calculator strategy is compliant with the ACT’s rules.

ACT Calculator Policy Checker

This check is based on the official ACT Calculator Policy, which prioritizes fairness and test security. Your eligibility depends on your calculator model, features, and how you manage backups.

What is the ACT Calculator Policy?

The ACT Calculator Policy is a set of rules designed to ensure fairness for all test-takers by standardizing the tools available during the math section of the exam. The core principle is to allow calculators as a tool for speeding up computation, not for solving problems outright using advanced software. This is why tools with Computer Algebra Systems (CAS) are banned. The question of whether you can you use 2 calculators on the ACT is common, and the policy is clear: you may only have one calculator on your desk and in operation at a time. However, you are strongly encouraged to bring a backup in case of malfunction.

This policy applies only to the mathematics test; calculators are not permitted on any other section. The ACT organization explicitly states that every problem on the math test can be solved without a calculator, but using a familiar and permitted device can significantly help with time management. Understanding the nuances of this policy is a critical part of preparing for test day.

The ACT’s Core Calculator Rules Explained

Instead of a mathematical formula, the ACT policy is a logical one based on a series of checks. The question of whether can you use 2 calculators on the ACT is just one part of this logic. Here’s a step-by-step breakdown of the rules to determine if your device is compliant.

ACT Calculator Rule Components

Rule Component	Meaning	Permitted Status	Typical Examples
Calculator Type	The category of the device.	Four-function, scientific, and graphing calculators are allowed.	TI-84 Plus, Casio fx-9750GII
Prohibited Features	Functions that give an unfair advantage.	Devices with QWERTY keyboards, pen-input, or wireless communication are banned.	Cell phones, tablets, laptops
CAS Functionality	Computer Algebra System (CAS) performs symbolic algebra (e.g., solves x+2=4 for x).	Strictly prohibited.	TI-89, TI-92, HP Prime
Backup Policy	Rules regarding a secondary calculator.	A backup is allowed but must be stored away and not on the desk.	Bringing a main graphing calculator and a backup scientific one.

Practical Examples (Real-World Use Cases)

Example 1: The Prepared Student

A student arrives with a TI-84 Plus CE, a widely permitted graphing calculator. They also have a TI-30XS MultiView (a scientific calculator) in their bag as a backup. During check-in, the proctor confirms the TI-84 is allowed. The student keeps the TI-30XS in their backpack. This is a perfect execution of the policy. They have a primary, approved device and follow the rules about the backup, which addresses the “can you use 2 calculators on the ACT” query correctly.

Example 2: The Prohibited Calculator Scenario

Another student brings a TI-89 Titanium. This calculator has a built-in Computer Algebra System (CAS), which is explicitly on the ACT’s prohibited list. The testing staff identifies the model and informs the student they cannot use it. Since the student did not bring a backup, they must take the math test without a calculator. This highlights the critical importance of checking your model against the official prohibited list before test day, rather than just assuming it’s fine.

How to Use This ACT Calculator Policy Checker

Our interactive tool is designed to simplify the ACT’s rules. Follow these steps to ensure you’re prepared:

1. Answer the Backup Question: Select ‘Yes’ or ‘No’ based on whether you’ll bring a second calculator. This helps clarify the rule about using one at a time.
2. Select Your Model Type: Be honest about your calculator model. If it’s a known prohibited model like a TI-89, choose it from the dropdown.
3. Identify Prohibited Features: Check if your device has a QWERTY keyboard or other banned hardware features.
4. Review Your Result: The tool will provide an instant “ALLOWED” or “NOT ALLOWED” status with an explanation. This gives you a clear action plan. Following this guidance is key, as is understanding the policy on whether can you use 2 calculators on the ACT.

Key Factors That Affect ACT Calculator Approval

Several factors determine whether your calculator will be allowed. Misunderstanding these can lead to being without a calculator on test day.

• Computer Algebra System (CAS): This is the most common reason for a calculator being banned. CAS can solve algebraic equations symbolically, which the ACT considers an unfair advantage.
• QWERTY Keypad: Any calculator with a typewriter-style (QWERTY) keyboard is prohibited.
• Communication Ability: Devices that can connect to the internet, use Bluetooth, or have any form of wireless communication are strictly forbidden. This includes smartwatches and phones.
• Backup Calculator Storage: While bringing a backup is wise, the policy on if can you use 2 calculators on the ACT is firm: only one is allowed on your desk. The backup must remain powered off and stored.
• Modifications Required: Some calculators are only allowed if modified. For example, those that make noise must have the sound turned off, and those with paper tape must have the tape removed.
• Proctor’s Discretion: Ultimately, the testing staff has the final say. If your calculator looks suspicious or has been modified in a way that is not permitted, they have the right to confiscate it.

Frequently Asked Questions (FAQ)

1. So, can you use 2 calculators on the ACT, literally at the same time?

No. You can only have one calculator on your desk and in use. You can bring a second one as a backup, but it must be put away. The rule is one at a time.

2. What is the most popular approved ACT calculator?

The Texas Instruments TI-84 Plus series is extremely popular and widely permitted. It’s a powerful graphing calculator without a prohibited CAS. Many high school math classes use it, so students are often familiar with it.

3. What happens if my calculator dies and I don’t have a backup?

You would have to complete the rest of the math test without a calculator. Test staff will not provide one. This is why bringing a backup or at least spare batteries is highly recommended.

4. Is the TI-Nspire allowed on the ACT?

This is tricky. The standard TI-Nspire (non-CAS) model is permitted. However, the TI-Nspire CAS model is strictly prohibited. You must know which version you have.

5. Can I use my phone’s calculator app?

Absolutely not. All cell phones and smart devices must be turned off and put away for the entire duration of the test, including breaks. Using one is a dismissible offense.

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

No, it is not required. A scientific calculator is sufficient, and all problems can be solved without any calculator. However, a graphing calculator can be a helpful tool if you know how to use it efficiently.

7. Does the ACT provide a list of approved calculators?

The ACT provides a list of explicitly *prohibited* calculators and features. Their policy is that any four-function, scientific, or graphing calculator is allowed as long as it’s *not* on the prohibited list. This is an important distinction.

8. What’s the best strategy regarding the backup calculator rule?

Bring a backup you are familiar with. Ensure both your primary and backup calculators have fresh batteries a few days before the test. This simple preparation eliminates a major source of potential test-day stress related to the question of whether can you use 2 calculators on the ACT.
