What is an ACT-Approved Calculator?
An ACT-approved calculator is a device that meets the specific guidelines set by the ACT organization for use during the mathematics section of the ACT test. The ACT aims to ensure fairness and prevent any unfair advantage, so they have strict rules about what calculator can you use on the ACT. Not all calculators are allowed, and understanding the ACT calculator policy is crucial before test day.
Essentially, you can use most four-function, scientific, or graphing calculators, as long as they do not have prohibited features like a Computer Algebra System (CAS), QWERTY keyboard, or wireless communication. Knowing what calculator can you use on the ACT helps you prepare appropriately.
Who Should Use This Information?
Students preparing for the ACT test, parents of ACT test-takers, teachers, and counselors should all be familiar with the ACT’s calculator rules. Using a prohibited calculator can lead to dismissal from the test center, and your scores may be canceled.
Common Misconceptions
A common misconception is that all graphing calculators are allowed. While many are, those with built-in CAS functionality (like the TI-89 or TI-Nspire CAS) are strictly forbidden. Another is that if a calculator was allowed on the PSAT or SAT, it’s automatically allowed on the ACT; this is not always true, as policies can differ. Always check the current ACT calculator policy for the most accurate information on what calculator can you use on the ACT.
ACT Calculator Policy Explained
The ACT calculator policy is designed to ensure a level playing field. Calculators are permitted on the Mathematics Test only. The core idea is that the calculator should be a tool to aid in computation, not to provide an unfair advantage through advanced functionalities or access to external information. Determining what calculator can you use on the ACT involves checking for specific prohibited features.
A calculator is generally **PROHIBITED** if it has any of the following features:
- Computer Algebra System (CAS): Calculators that can perform symbolic algebra (e.g., manipulate variables, factor, solve equations symbolically). Examples include TI-89, TI-92, TI-Nspire CAS, HP Prime, HP 48GII, and many Casio ClassPad models.
- QWERTY keyboard: Any calculator with a keyboard layout like a computer (A-Z keys).
- Wireless, Bluetooth, or Cellular Communication: Devices that can connect to the internet, other devices, or networks.
- Need for External Power: Calculators that must be plugged into an electrical outlet during the test.
- Paper Tape or Noise: Calculators that print, make noise, or have a paper tape.
- Part of Other Devices: Calculators on cell phones, smartphones, tablets, laptops, or smartwatches.
- Stylus or Pen-Based Input: Devices that use a stylus or are pen-based, like some PDAs or tablet-like calculators.
Some models are prohibited by name, even if they seem to fit general rules, often because they have CAS or other advanced features. Always check the official ACT website for the most current list of what calculator can you use on the ACT and prohibited models.
Variables Table (Prohibited Features)
| Feature | Meaning | Status if Present | Typical Examples |
|---|---|---|---|
| CAS | Computer Algebra System | Prohibited | TI-89, TI-Nspire CAS |
| QWERTY | QWERTY-style keyboard | Prohibited | Some older models |
| Wireless | Wireless, Bluetooth, Cellular | Prohibited | Calculators on phones |
| External Power | Needs to be plugged in | Prohibited | Desktop calculators |
| Paper Tape | Prints on paper tape | Prohibited | Adding machines |
| Part of Device | Integrated into phone/laptop | Prohibited | Smartphone calculator apps |
| Stylus/Pen | Uses a stylus for input | Prohibited | Some PDAs, ClassPad series |
If your calculator has NONE of these features and is not on the explicitly banned list, it is likely permitted. Standard scientific calculators (like TI-30X IIS) and many graphing calculators (like TI-83, TI-84 Plus, TI-84 Plus CE, Casio fx-9750GII) are generally allowed if they don’t have CAS.
Practical Examples
Example 1: TI-84 Plus CE
- Model: TI-84 Plus CE
- CAS: No
- QWERTY: No
- Wireless: No
- External Power: No
- Tape: No
- Part of Device: No
- Stylus: No
Result: Likely Permitted. The TI-84 Plus CE does not have CAS or any other prohibited features and is a very common calculator used on the ACT.
Example 2: TI-89 Titanium
- Model: TI-89 Titanium
- CAS: Yes
- QWERTY: No (but has many letter keys)
- Wireless: No
- External Power: No
- Tape: No
- Part of Device: No
- Stylus: No
Result: Prohibited. The TI-89 Titanium has a Computer Algebra System (CAS), which is explicitly banned by the ACT.
Example 3: Calculator on a Smartphone
- Model: Smartphone Calculator App
- CAS: Maybe (some apps have it)
- QWERTY: Yes (on-screen keyboard)
- Wireless: Yes (phone feature)
- External Power: No (battery)
- Tape: No
- Part of Device: Yes
- Stylus: Maybe (touchscreen)
Result: Prohibited. Calculators on smartphones are not allowed because they are part of a communication device and have other prohibited features.
How to Use This ACT Calculator Checker
- Enter Model Name: Type the model name of your calculator (e.g., “TI-84 Plus”).
- Answer Feature Questions: For each feature (CAS, QWERTY, etc.), select “Yes”, “No”, or “I don’t know” based on your calculator’s capabilities. If unsure about CAS, check your calculator’s manual or look for “CAS” in the model name or on the device.
- Check Eligibility: Click the “Check Eligibility” button.
- Review Results: The “Primary Result” will indicate if your calculator is “Likely Permitted,” “Prohibited,” or “Potentially Prohibited.” The “Details” section will show which features flagged it.
- Consult Official Policy: This checker is a guide. Always double-check the latest official ACT calculator policy on the ACT website, as rules and banned model lists can change. Knowing what calculator can you use on the ACT directly from the source is best.
If the result is “Potentially Prohibited” or you selected “I don’t know” for CAS, research your calculator model thoroughly or consult the official ACT website to confirm what calculator can you use on the ACT.
Key Factors That Affect ACT Calculator Eligibility
- Computer Algebra System (CAS): This is a major factor. Calculators with CAS are not allowed because they can perform symbolic algebra, which the ACT considers too advantageous.
- QWERTY Keyboard: Calculators with typewriter-like keyboards are prohibited to prevent storage of text or formulas easily.
- Communication Capabilities: Any form of wireless, Bluetooth, cellular, or internet connectivity is banned to prevent cheating or access to external information.
- Power Source: Calculators needing an external power outlet are not practical or permitted in the test environment.
- Physical Characteristics: Features like paper tape, noise, or being part of another device (phone, laptop) make a calculator prohibited.
- Stylus/Pen Input: Devices requiring a stylus are generally not allowed as they often have more advanced, PDA-like functionalities.
- Specific Model Bans: The ACT explicitly bans certain models by name, often due to CAS or other advanced features not easily categorized. It’s vital to know what calculator can you use on the ACT by checking this list.
Frequently Asked Questions (FAQ)
- 1. Can I use a TI-84 Plus CE on the ACT?
- Yes, the TI-84 Plus CE is generally permitted as it does not have CAS or other prohibited features. It’s one of the most popular calculators for the ACT.
- 2. Is the TI-Nspire allowed on the ACT?
- It depends. The TI-Nspire CX (non-CAS) is usually allowed, but the TI-Nspire CX CAS is prohibited due to its Computer Algebra System. You must know what calculator can you use on the ACT specifically regarding the Nspire line.
- 3. What happens if I bring a prohibited calculator to the ACT?
- If you are found using a prohibited calculator, you may be dismissed from the test center, and your scores will likely be canceled.
- 4. Do I need a graphing calculator for the ACT?
- No, you don’t *need* one. A scientific calculator is sufficient for all math problems. However, a graphing calculator (without CAS) can be helpful for some problems if you know how to use it effectively. Check our guide on ACT Math Prep.
- 5. Can I use my phone as a calculator on the ACT?
- No, phones, smartwatches, and any devices with communication capabilities are strictly prohibited during the entire test.
