What Does “Can You Use Two Calculators on the ACT” Mean?
The question “can you use two calculators on the ACT” is about understanding the official test day policy. It’s not about using two calculators simultaneously, but rather about the permissibility of bringing a backup device. The ACT’s policy is designed to ensure fairness and prevent academic dishonesty while acknowledging that technical issues, like a dead battery, can occur. The core of the policy is that you are allowed to have a backup, but specific rules govern its presence and use.
The ACT’s “Two Calculator” Formula Explained
There isn’t a mathematical formula, but a logical one. The policy can be broken down into a series of conditions. Your allowance to bring and potentially use a second calculator depends entirely on both calculators adhering to the ACT’s approved list.
| Variable | Meaning | Unit / Type | Typical Range |
|---|---|---|---|
| Primary Calculator | The main calculator you intend to use. | Device Model | Any 4-function, scientific, or graphing calculator not on the prohibited list. |
| Backup Calculator | A second calculator brought in case the primary one fails. | Device Model | Any 4-function, scientific, or graphing calculator not on the prohibited list. |
| Prohibited Features | Features that disqualify a calculator, such as CAS, Wi-Fi, or a QWERTY keyboard. | Boolean (Yes/No) | Must be ‘No’ for both calculators. |
| On-Desk Limit | The number of calculators you can have on your desk at one time. | Integer | Exactly 1. |
Practical Examples
Example 1: The Prepared Student
- Inputs:
- Primary Calculator: TI-84 Plus (Permitted)
- Backup Calculator: TI-30XIIS Scientific (Permitted)
- Result: Allowed. The student can bring both. The TI-30XIIS must stay under the desk unless the TI-84 Plus fails. She cannot use both at the same time.
Example 2: The Unprepared Student
- Inputs:
- Primary Calculator: TI-89 Titanium (Prohibited due to CAS)
- Backup Calculator: TI-84 Plus (Permitted)
- Result: Not Allowed. The proctor will likely confiscate the TI-89 before the test begins. The student will be allowed to use the TI-84 Plus, but the situation will cause unnecessary stress.
How to Use This “Can You Use Two Calculators on the ACT” Calculator
This tool functions as a policy checker to quickly determine if your calculator plan for test day is compliant with ACT rules. Here’s how to interpret it:
- Primary Calculator Check: First, determine if your main calculator is on the ACT’s prohibited list. If it is, you cannot bring it. Check the official approved ACT calculators list for details.
- Backup Calculator Check: Indicate if you are bringing a second device.
- Backup Policy Check: If you are bringing a backup, confirm that it is also a permitted model. A prohibited backup is not allowed.
- Review Your Result: The calculator will output a clear “Allowed,” “Conditionally Allowed,” or “Not Allowed” status with a detailed explanation of the official policy and how it applies to your situation.
Key Factors That Affect the ACT Calculator Policy
- Computer Algebra System (CAS): This is the most common reason a graphing calculator is prohibited. Models like the TI-89, TI-Nspire CAS, and HP Prime are banned.
- QWERTY Keypads: Calculators with typewriter-style keyboards are not allowed.
- Wireless Communication: Any device with Wi-Fi, Bluetooth, or infrared capabilities is forbidden unless the port is completely covered with opaque tape.
- Power Cords and Noise: Calculators that need to be plugged in are not allowed. If your calculator makes noise, the sound must be muted.
- Proctor Discretion: The test proctor has the final say. An unfamiliar or modified calculator may be inspected, so ensure your device clearly meets all requirements.
- Backup Is Not for Switching: You cannot switch between two calculators for different types of problems. The backup is strictly for emergency use if your primary calculator fails. More details can be found in our ACT math section tips.
Frequently Asked Questions (FAQ)
1. Can I have two calculators on my desk at the same time?
No. The official ACT policy states you may only have one calculator on your desk or in operation at a time. Your backup must be stored away (e.g., in your bag or under your desk).
2. What happens if my primary calculator dies during the test?
You should raise your hand and inform the proctor. You can then ask to retrieve your backup calculator to continue the test.
3. Can I use a scientific calculator and a graphing calculator?
Yes, as long as both are permitted models. However, you can’t switch between them. You would choose one as your primary and keep the other as a backup. See our guide on the best graphing calculators for high school.
4. Do I have to clear the memory on my calculator?
The ACT requires that you remove any programs with Computer Algebra System (CAS) functionality. While proctors rarely check, it is your responsibility to ensure your calculator complies.
5. Is the policy the same for the digital ACT?
For the digital ACT, a built-in Desmos calculator is provided. However, you are still allowed to bring your own handheld calculator as long as it meets the same policy guidelines.
6. Why would I want two calculators anyway?
The primary reason is for a backup. Batteries can die unexpectedly, or a calculator can malfunction. Having a backup provides peace of mind and is recommended by the ACT.
7. What is the most common mistake students make regarding the calculator policy?
Bringing a prohibited model, most often a calculator with a CAS like the TI-89 or TI-Nspire CAS. Always check your model against the official list before test day. Learn more in our ACT test day checklist.
8. Can I share my calculator with a friend?
No. Sharing calculators during the test is strictly prohibited.
