Calculators That Can Be Used On Act

What is an ACT Calculator Permissibility Checker?

An ACT Calculator Permissibility Checker is a tool designed to help students determine if the calculator they plan to use on the ACT exam is likely to be allowed under the official ACT calculator policy. The ACT has specific rules about which types of calculators are permitted and which are prohibited to ensure fairness and prevent academic dishonesty. This checker uses these rules, focusing on features like Computer Algebra Systems (CAS), wireless communication, QWERTY keyboards, and whether the calculator is part of another device like a phone or laptop. Understanding whether your calculator is permitted is crucial for test day preparation.

Anyone taking the ACT exam who plans to use a calculator should use an ACT Calculator Permissibility Checker or carefully review the official ACT policy. A common misconception is that all graphing calculators are allowed, but some advanced models, especially those with CAS, are prohibited. Another misconception is that if a calculator was allowed on the PSAT or SAT, it’s automatically allowed on the ACT; policies can differ. The ACT Calculator Permissibility Checker helps clarify these points based on features.

ACT Calculator Permissibility “Formula” and Logic Explanation

The permissibility isn’t determined by a single mathematical formula, but by a set of logical rules based on the calculator’s features, as outlined by the ACT. Here’s a step-by-step breakdown of the logic our ACT Calculator Permissibility Checker uses:

Check for Prohibited Features: The calculator first checks for features explicitly banned by the ACT. These include:
- Computer Algebra System (CAS)
- Wireless, Bluetooth, or internet connectivity
- QWERTY-style keyboard
- Being part of a phone, tablet, laptop, or smartwatch
- Making noise, having a paper tape, or needing an electrical outlet
Specific Model Checks: While this checker primarily uses features, the official policy also lists some specific models as prohibited (e.g., TI-89, TI-92, TI-Nspire CAS, HP 48GII, HP Prime). If a model is known to have CAS or other prohibited features, it’s flagged.
TI-Nspire Handling: The TI-Nspire series is treated specially. The TI-Nspire CAS is prohibited. The non-CAS TI-Nspire is generally allowed *if* it doesn’t have CAS or if the CAS functionality is disabled.
Assessment: If any explicitly prohibited feature is identified, the calculator is likely “Prohibited”. If no prohibited features are found, and it’s not on the prohibited list, it’s “Likely Allowed”. If it’s a borderline case (like a TI-Nspire non-CAS where CAS status is key), it might be “Check Again” or “Potentially Prohibited” with a note to verify CAS status.

Variables Table (Features Checked):

Feature/Variable	Meaning	Status	Impact on Permissibility
CAS	Computer Algebra System	Yes/No	Yes = Generally Prohibited
Wireless	Wireless/Bluetooth/Internet	Yes/No	Yes = Prohibited
QWERTY	QWERTY-like keyboard	Yes/No	Yes = Prohibited
Device Type	Part of phone, tablet, etc.	Yes/No	Yes = Prohibited
Noise/Tape/Outlet	Makes noise, has tape, needs outlet	Yes/No	Yes = Prohibited
TI-Nspire CAS	Is it a TI-Nspire with CAS?	Yes/No	Yes = Prohibited

Practical Examples (Real-World Use Cases)

Let’s see how the ACT Calculator Permissibility Checker evaluates different calculators:

Example 1: Texas Instruments TI-84 Plus CE

CAS: No
Wireless: No
QWERTY: No
Device Type: No (it’s a standalone calculator)
Noise/Tape/Outlet: No
TI-Nspire: No
Model: TI-84 Plus CE

Result: Likely Allowed. The TI-84 Plus CE is a standard graphing calculator without CAS and is widely permitted on the ACT.

Example 2: Texas Instruments TI-89 Titanium

CAS: Yes
Wireless: No
QWERTY: No (but has CAS)
Device Type: No
Noise/Tape/Outlet: No
TI-Nspire: No
Model: TI-89 Titanium

Result: Prohibited. The TI-89 Titanium has a Computer Algebra System (CAS), which is explicitly banned by the ACT.

Example 3: Casio fx-115ES PLUS

CAS: No
Wireless: No
QWERTY: No
Device Type: No
Noise/Tape/Outlet: No
TI-Nspire: No
Model: Casio fx-115ES PLUS

Result: Likely Allowed. This is a scientific calculator without prohibited features.

How to Use This ACT Calculator Permissibility Checker

Answer the Questions: Go through each question about your calculator’s features and select “Yes” or “No” (or the appropriate option for the TI-Nspire question).
Enter Model (Optional): If you know your calculator’s model number, enter it in the text box. The tool may recognize some common models.
Check Results: The “Primary Result” will indicate “Likely Allowed,” “Prohibited,” or “Check Again/Potentially Prohibited.”
Review Intermediate Results: This section will explain *why* the calculator received that status, listing the problematic features found or confirming the absence of them.
Read the Explanation: Understand the logic based on ACT rules.
Always Double-Check: The final authority is the official ACT calculator policy for your test date. Visit the ACT website (official ACT calculator policy) to confirm. Our ACT Calculator Permissibility Checker is a guide, not a guarantee.

Key Factors That Affect ACT Calculator Permissibility

Several factors determine whether a calculator is allowed on the ACT:

Computer Algebra System (CAS): This is a major factor. Calculators that can symbolically manipulate algebraic expressions (like factoring, solving equations symbolically) are generally banned.
Communication Capabilities: Any calculator with wireless, Bluetooth, infrared, or internet access is strictly prohibited to prevent cheating.
Keyboard Type: Calculators with QWERTY or typewriter-like keyboards are not allowed as they could be used to store notes or formulas extensively.
Integration with Other Devices: Calculators that are part of phones, tablets, laptops, or smartwatches are not permitted.
Power and Output: Calculators that need an electrical outlet, make noise, or have a paper tape are banned as they can be disruptive or provide an unfair advantage.
Specific Prohibited Models: The ACT explicitly lists certain calculator models (like the TI-89, TI-92, TI-Nspire CAS, HP 48GII, HP Prime) as prohibited, regardless of other features, often due to built-in CAS or other advanced capabilities. Refer to the ACT calculator rules.
Prohibited Software/Apps: Even on an allowed calculator, certain programs or apps might be prohibited if they grant an unfair advantage or violate test security.

Using an ACT Calculator Permissibility Checker helps you navigate these factors, but always consult the official ACT website for the most up-to-date policy before your test day.

Frequently Asked Questions (FAQ)

1. Are all graphing calculators allowed on the ACT?: No. While many graphing calculators (like the TI-83, TI-84 series) are allowed, those with CAS (like TI-89, TI-Nspire CAS) are prohibited. Use an ACT Calculator Permissibility Checker or the official list to verify.
2. What is a Computer Algebra System (CAS)?: A CAS is software that allows a calculator to perform symbolic manipulation of mathematical expressions (e.g., solve for x symbolically, factor polynomials). Calculators with CAS are not allowed on the ACT.
3. Can I use my phone’s calculator app?: No. Phones, smartwatches, tablets, and laptops, and their calculator apps, are strictly prohibited during the ACT.
4. What if my calculator is not on the prohibited list but has CAS?: If your calculator has CAS, it is generally prohibited, even if not explicitly listed by model name. The ACT prohibits features, not just specific models.
5. Is the TI-Nspire allowed?: The TI-Nspire CAS is prohibited. The non-CAS TI-Nspire or a TI-Nspire with CAS disabled *might* be allowed, but you must ensure CAS is off. It’s risky; check the latest ACT policy carefully.
6. Where can I find the official ACT calculator policy?: The most current policy is always available on the official ACT website. Search for “ACT calculator policy” or visit their test day information section. See our link to the latest ACT policy.
7. What happens if I bring a prohibited calculator?: If you are found with a prohibited calculator, it will be confiscated, and you may be dismissed from the test, and your scores could be canceled.
8. Does this ACT Calculator Permissibility Checker guarantee my calculator is allowed?: No. This checker is a guide based on published ACT rules. The final decision rests with the test center staff and the official ACT policy on your test date. Always verify with the official source. See how to use this checker for more guidance.
