ACT Approved Calculators Checker
Your essential tool for verifying if your calculator is permitted for the ACT test.
Is Your Calculator ACT Approved?
Type your calculator’s model name. The checker will provide its status in real-time.
Enter a model to check its status.
What are ACT Approved Calculators?
The ACT has a strict policy regarding which calculators are allowed during the math portion of the test. The main goal is to ensure fairness and prevent any student from having an unfair advantage. Generally, any four-function, scientific, or graphing calculator is permitted, as long as it is not on the official prohibited list. All questions on the ACT Math test can be solved without a calculator, but using a familiar and approved calculator can be a significant time-saver.
Prohibited Calculators and Features
The ACT explicitly forbids certain calculators and features to maintain a level playing field. The most common reason for a calculator to be banned is the presence of a Computer Algebra System (CAS). CAS can solve algebraic equations, which is not allowed.
Prohibited devices include:
- Calculators with built-in CAS, such as the TI-89, TI-92, and TI-Nspire CAS.
- Laptops, tablets, or mobile phones.
- Calculators with a QWERTY keyboard.
- Devices with internet access.
Calculators Requiring Modification
Some calculators are allowed, but only after certain modifications are made. For example:
- Programs: Any programs with CAS functionality must be removed.
- Noise: Devices that make noise must be silenced.
- Infrared Ports: Data ports must be completely covered with opaque tape.
How to Use This ACT Approved Calculators Checker
Using this tool is straightforward. Follow these simple steps:
- Locate the model name on your calculator. This is usually printed on the front.
- Type the model name into the input field above. You don’t need to be exact; partial matches will work.
- The result will instantly tell you if your calculator is ‘Approved’, ‘Prohibited’, or ‘Approved with Modifications’.
Key Factors That Affect ACT Calculator Approval
Understanding the reasoning behind the rules can help you choose the right calculator. Here are the key factors the ACT considers:
- Computer Algebra System (CAS): This is the most significant factor. If a calculator can symbolically solve algebra problems, it’s banned.
- QWERTY Keyboard: Calculators with a typewriter-style keyboard are not allowed.
- Communication: Devices that can communicate with other devices (via infrared, Bluetooth, or Wi-Fi) are prohibited.
- Power Cords: A calculator cannot be used if it needs to be plugged into an electrical outlet.
- Paper Tape: Calculators that print to a roll of paper are only allowed if the paper mechanism is removed.
- Non-calculator Functionality: Phones, smartwatches, and laptops are never allowed, even if you only use their calculator app.
Frequently Asked Questions (FAQ)
- Can I use a TI-84 Plus?
- Yes, the entire TI-84 Plus series, including the CE and Python editions, is approved for the ACT.
- Is the TI-Nspire allowed?
- The standard TI-Nspire (non-CAS) is permitted. However, the TI-Nspire CAS model is prohibited.
- What if my calculator is not on any list?
- If your calculator is not on the prohibited list and doesn’t have any forbidden features (like CAS or a QWERTY keyboard), it is likely allowed. When in doubt, have a backup option.
- Do I need a graphing calculator for the ACT?
- No, all problems can be solved without a calculator. However, a graphing calculator can be helpful for visualizing problems and saving time. A simpler scientific calculator is also a great choice.
- What happens if I bring a prohibited calculator?
- Test proctors are trained to identify prohibited calculators. If you are caught with one, you may be dismissed from the test, and your score will be invalidated.
- Can I share my calculator with another student?
- No, sharing calculators during the test is not permitted.
- Should I bring a backup calculator?
- Yes, it is highly recommended to bring a backup calculator and extra batteries, just in case your primary one fails.
- Are there calculators available at the test center?
- No, the testing center will not provide calculators. You must bring your own.
