ACT Calculator Policy Checker
Instantly check if you can use a solar calculator on the ACT.
Is Your Calculator ACT-Approved?
Answer the following questions about your calculator to determine if it meets the official ACT calculator policy. This tool helps you see if you can use your solar calculator on the ACT or if you need a different device.
Is your calculator solar, battery-powered, or does it require an outlet?
Calculators that print are prohibited.
Noisy devices that can cause disturbances are not allowed.
Cell phones, smart watches, and laptops are strictly forbidden.
Calculators with typewriter-like keyboards (e.g., TI-89) are prohibited.
Calculators that can solve algebraic equations (e.g., TI-Nspire CAS) are banned.
What is the ACT Calculator Policy?
The ACT calculator policy is a set of rules designed to ensure fairness and test security for all students. The main goal is to prevent any student from having an unfair advantage through a powerful calculator while also allowing most students to use a device they are familiar with. A common question is, can you use a solar calculator on the ACT? The simple answer is yes, provided it does not have any prohibited features. Solar power itself is not a disqualifying factor. The policy focuses on functionality, not the power source.
Anyone taking the ACT math test should use this policy to check their device. The most common misconception is that expensive or graphing calculators are banned, which isn’t true. Many graphing calculators are perfectly acceptable. The ban applies to specific features like computer algebra systems (CAS), QWERTY keyboards, and wireless communication. Understanding whether you can you use a solar calculator on the ACT is the first step to being prepared. For more information, check out the official ACT prep course resources.
ACT Calculator Compliance Rules Explained
There isn’t a mathematical formula to determine if a calculator is allowed. Instead, the ACT provides a checklist of prohibited features. A calculator is deemed “prohibited” if it has one or more of these features. The core question, “can you use a solar calculator on the ACT,” is answered by checking it against these rules.
Below is a table breaking down the key features the ACT checks for. If your calculator has any feature in the ‘Prohibited’ category, you cannot use it on the test.
| Feature | Meaning | Status | Typical Example |
|---|---|---|---|
| Solar Power | Calculator runs on light. | Permitted | Most basic scientific calculators (e.g., TI-30X) |
| Computer Algebra System (CAS) | Can manipulate and solve symbolic algebra. | Prohibited | TI-Nspire CAS, HP Prime |
| QWERTY Keyboard | A typewriter-style keyboard. | Prohibited | TI-89, TI-92 |
| Paper Tape | Prints a record of calculations. | Prohibited | Adding machines |
| Makes Noise | Beeps or makes sounds that cannot be muted. | Prohibited | Talking calculators (unless pre-approved for accommodation) |
| Communication Device | Part of a phone, tablet, or laptop. | Prohibited | Any smartphone calculator app |
| Needs Outlet | Must be plugged into a wall to work. | Prohibited | Desktop calculators |
Practical Examples (Real-World Use Cases)
Example 1: The Standard Scientific Calculator
A student wants to bring a Texas Instruments TI-30X IIS, a very common scientific calculator that is both solar and battery-powered.
- Inputs: Power Source (Solar/Battery), No Paper Tape, No Noise, Not a Communication Device, No QWERTY, No CAS.
- Output: PERMITTED.
- Interpretation: This calculator is perfectly acceptable. It meets all ACT guidelines, confirming that you can you use a solar calculator on the ACT when it’s a standard model like this.
Example 2: The Advanced Graphing Calculator
Another student has a TI-89 Titanium graphing calculator.
- Inputs: Power Source (Battery), No Paper Tape, No Noise, Not a Communication Device, Yes to QWERTY keyboard, Yes to CAS.
- Output: PROHIBITED.
- Interpretation: This calculator is banned because it has both a Computer Algebra System (CAS) and a QWERTY keyboard. It provides an unfair advantage according to the SAT vs ACT calculator rules.
How to Use This ACT Calculator Policy Checker
Using this tool is straightforward and provides instant clarity on whether you can you use a solar calculator on the ACT. Follow these simple steps:
- Select Power Source: Choose how your calculator is powered. Note that “Needs Electrical Outlet” will immediately prohibit the device.
- Answer Feature Questions: For each feature, select “Yes” or “No” from the dropdown menu. These questions cover all the major restrictions in the ACT’s policy.
- Review the Result: The large result box will immediately update to “PERMITTED” or “PROHIBITED”.
- Understand the Reasons: Below the main result, the “Prohibited Features” list will tell you exactly why your calculator is not allowed. If all features are compliant, it will state “None”.
- Reset if Needed: Click the “Reset” button to clear your selections and start over with a new calculator. This is helpful for comparing different models you might own.
This calculator helps you make an informed decision and avoid a stressful situation on test day. Knowing your best calculator for ACT math is a key part of preparation.
Key Factors That Affect Calculator Permissibility
Several key factors determine whether your calculator is allowed. While the question of if you can you use a solar calculator on the ACT is a common starting point, the ACT is more concerned with the following functionalities:
- Computer Algebra System (CAS): This is the most significant factor. A CAS can solve equations, factor, and expand expressions symbolically. This goes beyond numerical calculation and is strictly prohibited as it can solve many ACT math problems automatically.
- QWERTY Keyboards: Any calculator with a keyboard laid out like a computer (in QWERTY format) is banned. This is to prevent the use of devices with text-storing capabilities.
- Communication Ability: Any device that can communicate wirelessly (e.g., Wi-Fi, Bluetooth, Infrared) is banned. This includes phones, smart watches, and certain advanced calculators with data ports.
- External Power Requirement: Your calculator must be battery and/or solar-powered. You cannot use a device that needs to be plugged into an electrical outlet. This is a logistical and fairness rule.
- Disturbing Features: Any calculator that makes noise it cannot be muted or has a paper tape that prints results is considered a disturbance and is not allowed in the testing room.
- Device Type: The calculator must be a dedicated calculator. You cannot use the calculator function on a laptop, tablet, or phone. Before the test, review your options from our list of free practice tests.
Frequently Asked Questions (FAQ)
1. So, can you use a solar calculator on the ACT?
Yes, absolutely. The fact that a calculator is solar-powered has no bearing on its permissibility. As long as it doesn’t have any other prohibited features (like a QWERTY keyboard or CAS), it is allowed.
2. What happens if I bring a prohibited calculator to the test?
The test proctor will not allow you to use it. You will have to take the math section without a calculator. You will not be provided with a replacement. This is why checking your device with a tool like this beforehand is critical.
3. Is a TI-84 Plus allowed?
Yes, the TI-84 Plus family (including the Plus CE) is one of the most popular and widely approved graphing calculators for the ACT. It does not have a CAS or a QWERTY keyboard.
4. Can I share my calculator with another student?
No. Sharing calculators during the test is strictly prohibited under all circumstances.
5. Do I need to clear the memory on my graphing calculator?
While the ACT policy doesn’t always require it, it’s a good practice to clear your calculator’s memory before the test to ensure no programs or notes are stored. Some proctors may ask to see that the memory has been reset.
6. Is the calculator policy the same for the SAT?
The policies are very similar but not identical. Both ban phones, CAS on the non-calculator section, and QWERTY keyboards. However, you should always check the specific policy for each test. For a detailed comparison, see our SAT vs ACT guide.
7. What if my calculator runs out of battery?
You are responsible for ensuring your calculator works. It’s highly recommended to install fresh batteries before test day or bring a backup calculator. A solar-powered calculator is a great choice to minimize this risk. This is a key advantage when considering if you can you use a solar calculator on the ACT.
8. Are there any calculators that are specifically recommended?
The ACT does not recommend specific brands, but popular approved models include the TI-84 Plus, TI-Nspire (non-CAS version), and basic scientific calculators like the TI-30X series. Your online tutoring professional can help you choose one.
