What Does “Can You Use 2 Calculators on the ACT” Really Mean?

The question of whether a student can use 2 calculators on the ACT is a frequent source of confusion. The short answer is yes, you can bring a backup calculator, but you cannot have two calculators on your desk or actively use them simultaneously during the test. The ACT’s policy is designed to allow for a backup in case of technical failure, not to provide an advantage by using two different devices for different functions. Understanding this distinction is key to a smooth test day experience.

The Official ACT Calculator Policy Explained

The ACT has a detailed policy to ensure fairness and test security. While all math problems can be solved without a calculator, using one can be a significant time-saver. The policy centers on two main areas: the type of calculator and how it’s used.

Permitted vs. Prohibited Calculators

You may use any 4-function, scientific, or graphing calculator, as long as it is not on the prohibited list. Key restrictions include calculators with built-in computer algebra systems (CAS), QWERTY keyboards (like on a phone), or those that require an external power source. Devices like phones, tablets, and laptops are strictly forbidden. You can find more details by searching for the ACT Calculator Policy.

The “Backup Calculator” Rule

The ACT explicitly allows you to bring a backup calculator. However, it must be stored away (e.g., in your bag or under your desk) and cannot be on your desk at the start of the test. You may only retrieve and use the backup if your primary calculator fails. You are not allowed to switch back and forth between two calculators. This is the official answer to “can you use 2 calculators on the ACT” – one for active use, and one for emergency backup only.

Calculator Policy Summary

Variable	Meaning	Unit/Type	Typical Range
Primary Calculator	The main calculator you intend to use.	Approved Device	TI-84, TI-Nspire (non-CAS), most scientific calculators
Backup Calculator	A second calculator brought in case the primary one fails.	Approved Device	Any approved model, often a simpler one.
Test Day Usage	How the calculators are handled during the exam.	Policy Rule	Only one calculator on desk at a time.

Practical Examples

Example 1: The Prepared Student

• Inputs:
  • Primary Calculator: Approved (TI-84 Plus)
  • Backup Calculator: Approved (Basic Scientific)
  • Usage Plan: Backup only
• Result: Allowed. The student can keep the scientific calculator in their bag. If the TI-84 Plus fails, they can ask the proctor for permission to use the backup. This is the correct way to handle the “can you use 2 calculators on the act” scenario.

Example 2: The Misinformed Student

• Inputs:
  • Primary Calculator: Approved (Graphing)
  • Backup Calculator: Approved (Scientific)
  • Usage Plan: Use both simultaneously
• Result: Not Allowed. Attempting to use two calculators at once is a violation of ACT policy and could lead to dismissal from the test. Proctors will enforce the “one calculator on the desk” rule.

How to Use This Calculator Policy Checker

Using this tool is straightforward and helps clarify the rules so you can be confident on test day.

1. Select Primary Calculator Status: Choose whether your main calculator is on the ACT’s approved list. If you’re unsure, check the official ACT test day rules.
2. Select Backup Calculator Status: Do the same for your backup calculator.
3. Define Your Usage Plan: Be honest about how you intend to use the second calculator. This is the most important factor.
4. Check Eligibility: Click the button to see the outcome. The result will tell you if your plan is compliant with ACT policy.

Key Factors That Affect Calculator Eligibility on the ACT

• Prohibited Features: The most common reason a calculator is banned is due to features like a Computer Algebra System (CAS), which can solve algebraic equations symbolically.
• QWERTY Keyboards: Any calculator with a typewriter-style keyboard is prohibited.
• Communication Capability: Devices that can communicate via Wi-Fi, Bluetooth, or infrared are not allowed.
• Power Source: Calculators that need to be plugged into an outlet are not permitted.
• Noise: Calculators that make noise must be muted.
• Proctor Discretion: Ultimately, the test proctor has the final say. Always be respectful and follow their instructions. Wondering “can you use 2 calculators on the ACT” is valid, but the proctor’s word is final.

Frequently Asked Questions (FAQ)

1. Can you use 2 calculators on the ACT at the same time?

No. You are only permitted to have one calculator on your desk at any given time. Using two simultaneously is a violation of the rules.

2. What happens if my main calculator dies during the test?

If you brought an approved backup calculator, raise your hand and inform the proctor. They will typically allow you to retrieve your backup and continue.

3. Do I have to tell the proctor I have a backup calculator?

No, you do not need to declare it beforehand, but it must be kept out of sight (e.g., in your bag) unless your primary calculator fails.

4. Is a TI-89 allowed on the ACT?

No, the Texas Instruments TI-89 is a prohibited model because it has a built-in CAS.

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

Absolutely not. Cell phones and all other communication devices must be turned off and put away for the entire duration of the test, including breaks.

6. What’s the best backup calculator to bring?

A simple, reliable scientific calculator that you are familiar with is an excellent choice. It doesn’t need to be a fancy graphing model.

7. If I use my backup, can I switch back to my primary if it starts working again?

This is unlikely to be permitted. Once you switch, you should expect to finish the test with your backup calculator.

8. Does this policy apply to the Science section too?

No. Calculators are only permitted for the Mathematics section of the ACT. They are not allowed during the English, Reading, or Science sections.
