Act Graphing Calculator Allowed

Determine if your graphing calculator is permitted on the ACT exam instantly.

What is ACT Graphing Calculator Allowed?

The term "act graphing calculator allowed" refers to the specific set of policies enforced by ACT, Inc. regarding the types of calculators students can bring into the testing room. Unlike the SAT, which has a slightly more permissive policy, the ACT maintains strict guidelines to ensure test integrity. While most basic scientific and graphing calculators are permitted, any device with a Computer Algebra System (CAS), QWERTY keyboard, or internet access is strictly prohibited. Understanding these rules is crucial for test day success to avoid having your calculator confiscated.

ACT Calculator Policy Formula and Explanation

Determining if a calculator is allowed involves checking specific hardware attributes against a banned list. The logic is not based on processing power, but on specific features that could give a student an unfair advantage or facilitate cheating.

The Logic Formula

Allowed = (No CAS) AND (No QWERTY) AND (No Internet) AND (Not in Banned Model List)

Variable Definitions for Eligibility

Variable	Meaning	Unit/Type	Typical Range
CAS	Computer Algebra System capability	Boolean (True/False)	Must be False
QWERTY	Standard typewriter keyboard layout	Boolean (True/False)	Must be False
Connectivity	WiFi, Bluetooth, or Cellular hardware	Boolean (True/False)	Must be False
Model ID	Specific manufacturer model number	String	TI-84, Casio fx-9750

Practical Examples

Here are realistic scenarios using the ACT graphing calculator allowed logic to determine eligibility.

Example 1: Texas Instruments TI-84 Plus CE

• Inputs: Brand: Texas Instruments, Model: TI-84 Plus CE, CAS: No, QWERTY: No.
• Result: Allowed.
• Explanation: This model lacks a CAS and QWERTY keyboard. It is the standard for ACT test takers.

Example 2: TI-Nspire CX II CAS

• Inputs: Brand: Texas Instruments, Model: TI-Nspire CX II CAS, CAS: Yes, QWERTY: No.
• Result: Not Allowed.
• Explanation: Despite not having a QWERTY keyboard, the inclusion of "CAS" in the model name and functionality makes it prohibited.

Key Factors That Affect ACT Calculator Eligibility

Several hardware and software factors determine if a device falls under the "act graphing calculator allowed" category. Test proctors are trained to spot these specific attributes.

• Computer Algebra System (CAS): This is the most common reason for rejection. CAS calculators can solve equations symbolically (e.g., factoring x^2+5x+6 automatically), which is prohibited.
• QWERTY Keyboard: Any device with a keyboard layout similar to a typewriter is banned. This includes devices like the TI-92.
• Memory Storage: While having memory is allowed, proctors may require you to clear the memory before the test begins to ensure no stored programs or notes are used.
• Power Source: Calculators must be battery-operated. You cannot plug a calculator into a wall outlet during the test.
• Sound: Calculators that make noise must have the sound feature turned off. If it beeps, it may be removed.
• Mobile Apps: Using a calculator app on a smartphone, tablet, or smartwatch is strictly forbidden, even if the app mimics an allowed model.

Frequently Asked Questions (FAQ)

Is the TI-89 allowed on the ACT?

No, the TI-89 is not allowed because it features a Computer Algebra System (CAS).

Can I use a Casio fx-CG50 on the ACT?

Yes, the Casio fx-CG50 is generally allowed because it does not have CAS capabilities, unlike the Casio fx-CG500.

What happens if I bring a banned calculator?

The test proctor will dismiss you from the test if you are found using a prohibited calculator, and your scores will likely be cancelled.

Do I need to remove programs from my calculator?

While not strictly required to bring it in, proctors have the authority to inspect and ask you to delete programs or documents with memory.

Are iPad calculator apps allowed?

No, tablets and iPads are not permitted as calculators on the ACT.

Does the calculator policy change every year?

Rarely. The ACT policy is stable, but it is always best to check the official ACT student website for the most current updates before test day.

Can I use a calculator that prints paper tape?

No, calculators with paper tape (often used in accounting) are prohibited.

Is the HP Prime allowed?

The HP Prime is generally not allowed in its default CAS mode. However, some versions allow you to disable CAS. It is highly risky to bring it; a TI-84 or Casio non-CAS model is safer.
