What Calculator Can You Use on ACT? – Permitted Calculator Checker
ACT Calculator Policy Checker
Enter your calculator’s model and features to check if it’s likely allowed on the ACT test.
What is the ACT Calculator Policy?
The ACT (American College Testing) has a specific policy regarding which calculators are permitted during the mathematics section of the test. The main goal of the policy is to ensure fairness and prevent any student from having an unfair advantage through the use of advanced calculator features. Understanding what calculator can you use on ACT is crucial before test day.
Students are allowed to use a calculator on the ACT mathematics test, but not on any other section. It’s the student’s responsibility to bring an acceptable calculator and ensure it’s in working order with fresh batteries. You should know what calculator can you use on ACT well in advance.
Common misconceptions include believing all graphing calculators are allowed (some with CAS are not) or that any scientific calculator is fine (those with QWERTY keyboards are not).
ACT Calculator Rules and Prohibited Features
The ACT explicitly prohibits calculators with certain features. The core idea is to prevent access to tools that perform symbolic algebra, communicate wirelessly, make noise, or require an external power source. Here’s a breakdown of prohibited features:
- Calculators with built-in Computer Algebra Systems (CAS): These can perform symbolic manipulation (e.g., solve equations like ‘x + y = z’ for x, simplify expressions symbolically). Examples include TI-89, TI-92, TI-Nspire CAS, HP 48GII, HP Prime, and Casio ClassPad series.
- Calculators with QWERTY keyboards: Any device with a typewriter-like keyboard is not allowed.
- Calculators that can communicate wirelessly: This includes infrared, Bluetooth, or Wi-Fi capabilities.
- Calculators that use an electrical outlet, make noise, or have a paper tape: They must be battery-operated and silent.
- Pen-input or stylus-required devices: Unless it’s a TI-Nspire (non-CAS) with its original stylus, these are generally not allowed. This includes most tablet-based calculators.
- Cell phone calculators, smartwatches, or any communication devices.
Knowing what calculator can you use on ACT means checking for these features.
| Feature/Model Type | Status | Examples/Notes |
|---|---|---|
| Most four-function, scientific, or basic graphing calculators | Permitted | TI-83, TI-84 Plus, Casio fx-9750GII |
| Calculators with Computer Algebra System (CAS) | Prohibited | TI-89, TI-Nspire CAS, HP Prime |
| Calculators with QWERTY keyboards | Prohibited | – |
| Wireless communication | Prohibited | Bluetooth, Wi-Fi, Infrared |
| Needs external power | Prohibited | Must be battery-powered |
| Pen/Stylus based (most) | Prohibited | Exception: TI-Nspire non-CAS |
| TI-89, TI-92, TI-Nspire CAS | Prohibited | Explicitly banned |
| TI-83, TI-84 (any version without CAS) | Permitted | Widely used and allowed |
This table helps understand what calculator can you use on ACT.
Practical Examples
Let’s see how to determine what calculator can you use on ACT with examples:
Example 1: TI-84 Plus CE
- Model: TI-84 Plus CE
- CAS: No
- QWERTY: No
- Wireless: No
- Outlet: No
- Pen/Stylus: No
- Result: Likely Permitted. The TI-84 series (without CAS) is generally allowed.
Example 2: TI-Nspire CX CAS
- Model: TI-Nspire CX CAS
- CAS: Yes
- QWERTY: No
- Wireless: No (unless with wireless module, which is prohibited)
- Outlet: No
- Pen/Stylus: Yes (but CAS is the main issue)
- Result: Prohibited due to CAS.
Example 3: Casio ClassPad fx-CP400
- Model: Casio ClassPad fx-CP400
- CAS: Yes
- QWERTY: No (but has on-screen)
- Wireless: No
- Outlet: No
- Pen/Stylus: Yes
- Result: Prohibited due to CAS and stylus/touch interface typical of ClassPad.
How to Use This ACT Calculator Checker
Using our “What Calculator Can You Use on ACT” checker is simple:
- Enter the Model Name: Type the model name of your calculator as accurately as possible.
- Answer Feature Questions: Select “Yes,” “No,” or “I don’t know” for each feature (CAS, QWERTY, etc.). If you select “I don’t know,” the checker will rely more on the model name if it’s recognized, or give a more cautious result.
- Check Results: The tool will instantly show “Permitted,” “Prohibited,” or “Check Model/Features.” It will also give a reason based on your input.
- Read Intermediate Results: See a summary of the features you selected.
If the result is “Check Model/Features,” it means either the model name wasn’t fully recognized or you were unsure about a critical feature. In this case, double-check your calculator against the official ACT calculator policy on their website.
Key Factors That Affect Permissibility
Several factors determine what calculator can you use on ACT:
- Computer Algebra System (CAS): The most common reason for prohibition. If it has CAS, it’s not allowed.
- QWERTY Keyboard: Any calculator resembling a computer keyboard is banned.
- Wireless Communication: No form of wireless data transfer is permitted.
- Power Source: Must be battery-operated.
- Input Method: Pen/stylus input is generally prohibited, with a specific exception for the non-CAS TI-Nspire.
- Explicit Model Bans: The ACT website lists specific models that are prohibited (e.g., TI-89, TI-92, TI-Nspire CAS, HP Prime, HP 48GII, Casio ClassPad). Even if you think it lacks prohibited features, if it’s on the banned list, it’s out.
- Modifications: Any modification to an allowed calculator that gives it prohibited features will make it disallowed.
Frequently Asked Questions (FAQ)
Q1: Is the TI-84 Plus allowed on the ACT?
A1: Yes, the TI-84 Plus, TI-84 Plus CE, and other TI-84 versions that do NOT have CAS are generally permitted.
Q2: Is the TI-Nspire allowed on the ACT?
A2: It depends. The TI-Nspire (non-CAS) is allowed, even with its touchpad/stylus. However, the TI-Nspire CAS is PROHIBITED.
Q3: What if I don’t know if my calculator has CAS?
A3: Look for a “CAS” button or menu option, or check the calculator’s manual or model number online. If unsure, it’s safer to bring a more basic calculator or one you know is permitted.
Q4: Are all scientific calculators allowed?
A4: Most standard scientific calculators are allowed. However, if a scientific calculator has a QWERTY keyboard or CAS (rare but possible), it would be prohibited.
Q5: What happens if I bring a prohibited calculator?
A5: You will not be allowed to use it during the test. The test proctor will likely ask you to put it away, and you may have to take the math section without a calculator or with one provided by the center if they have any (which is unlikely).
Q6: Can I use my phone as a calculator?
A6: No, cell phones, smartwatches, and any devices with communication capabilities are strictly prohibited.
Q7: Do I need the most advanced permitted calculator?
A7: No. While a graphing calculator can be helpful, the ACT math test is designed so that a calculator is not strictly necessary for any question. A good scientific calculator is often sufficient. Knowing what calculator can you use on ACT and being comfortable with it is key.
Q8: Where can I find the official ACT calculator policy?
A8: The most up-to-date policy is always on the official ACT website (act.org). Always check there before your test date.
