What is the Policy on AET Calculators?

When preparing for any standardized test, including the AET, a common question is: can you use a scientific calculator on the AET? The answer depends on the specific rules set by the test administrator, which are designed to ensure fairness and test security. While rules can vary, most standardized tests follow a similar framework for what is and isn’t allowed.

Generally, the policy aims to permit calculators as tools for computation, not as sources of unfair advantages. This means most basic four-function and scientific calculators are acceptable. However, devices with advanced functionalities like storing text, accessing the internet, or solving algebraic equations symbolically are almost universally prohibited. Our standardized test calculator rules guide provides more general information on this topic.

Permitted vs. Prohibited Calculator Features

Understanding the core differences between allowed and banned features is the key to choosing the right device. The policy isn’t about specific brand names but rather about the capabilities of the calculator.

This table outlines common features and their typical allowance status for tests like the AET.

Feature Type	Usually Permitted	Usually Prohibited
Basic Functions	Addition, Subtraction, Multiplication, Division	N/A
Scientific Functions	Sin, Cos, Tan, Log, Exponents, Square Roots	N/A
Graphing	Permitted on some tests (e.g., ACT, SAT) as long as it has no CAS.	Often prohibited, especially if it includes a CAS.
Computer Algebra System (CAS)	Never	Any calculator with CAS (e.g., TI-89, HP 50g).
Keyboard	Numeric keys only	QWERTY-style keyboards.
Connectivity	None	Wi-Fi, Bluetooth, Infrared ports.
Power	Battery or solar-powered	Requires an external power outlet.
Other	Silent operation	Makes noise, has a paper tape, or is part of a phone/tablet.

How to Use This AET Calculator Policy Checker

Our tool is designed to give you a clear indication of your calculator’s eligibility for the AET. Follow these simple steps:

1. Identify Your Calculator’s Features: Look at your calculator and check for the features listed in the tool, such as graphing, a QWERTY keyboard, or a “CAS” label.
2. Select the Checkboxes: Check the box for each feature your calculator possesses.
3. Check Compliance: Click the “Check Compliance” button to see the result.
4. Review the Details: The result will show “Likely Allowed” or “Likely Not Allowed” and provide a list of reasons based on your selections. This helps you understand exactly which feature is problematic. For a full exam day checklist, make sure to verify the official AET rules.

Practical Examples

Let’s look at two common scenarios to understand how the rules apply.

Example 1: A Standard Scientific Calculator (e.g., TI-30X)

• Inputs: “Is it a scientific calculator?” is checked. All other boxes are unchecked.
• Analysis: This calculator has standard scientific functions but lacks advanced features like graphing, CAS, or a QWERTY keyboard. It is battery-powered and silent.
• Result: Likely Allowed. It fits the profile of a standard computational tool without providing unfair advantages.

Example 2: An Advanced CAS Graphing Calculator (e.g., TI-89)

• Inputs: “Is it a scientific calculator?”, “Does it have graphing capabilities?”, and “Does it have a Computer Algebra System (CAS)?” are checked.
• Analysis: The key prohibited feature here is the Computer Algebra System (CAS). Even though it’s also a scientific and graphing calculator, the CAS functionality allows it to solve algebraic equations, which is not permitted.
• Result: Likely Not Allowed. The presence of a CAS is an automatic disqualifier for most standardized tests.

Key Factors That Affect AET Calculator Eligibility

• Computer Algebra System (CAS): This is the most critical factor. If your calculator can perform symbolic algebra (factor, expand, solve for x), it is almost certainly banned.
• QWERTY Keyboard: Calculators with typewriter-like keyboards are prohibited as they could be used to store notes.
• Wireless Communication: Any device that can communicate with other devices (via Bluetooth, Wi-Fi, etc.) is not allowed.
• Power Source: Calculators must be battery-operated. Devices requiring an electrical outlet are forbidden.
• Noise and Peripherals: Calculators that make noise or print to a paper tape are disruptive and not permitted.
• Part of Another Device: You cannot use the calculator function on a smartphone, tablet, or laptop. The device must be a standalone calculator. For more help, see our AET test prep guide.

Frequently Asked Questions (FAQ)

1. Do I need to clear the memory on my calculator before the AET?

While some tests require it, others do not. As a best practice, you should clear any stored programs or notes unless the official AET policy explicitly states it’s unnecessary. Check the latest official AET rules for confirmation.

2. What if my calculator is not on the official approved list?

If there’s an approved list, stick to it. If there isn’t one, use the feature-based rules. If your calculator has none of the prohibited features (like CAS or a QWERTY keyboard), it is likely fine.

3. Can I bring a backup calculator?

Most testing centers allow you to bring a backup calculator. It’s a wise precaution in case your primary one fails. Ensure your backup also meets the approved criteria.

4. Are all scientific calculators allowed on the AET?

No. While most are, some advanced “scientific” models include a CAS, which would make them prohibited. The term “scientific” is broad, so you must check for prohibited features. Our checker helps you determine if your specific model raises any red flags.

5. Is a graphing calculator considered a scientific calculator?

Yes, all graphing calculators are also scientific calculators, but not all scientific calculators have graphing functions. The key is whether the graphing calculator also has a prohibited feature like a CAS. A non-CAS graphing calculator is often allowed. Learn more about graphing calculator basics.

6. What happens if I bring a prohibited calculator?

You will not be allowed to use it. In the worst-case scenario, you could be dismissed from the test and have your score canceled.

7. Can I share my calculator with another test-taker?

No. Sharing calculators is strictly forbidden to prevent communication between test-takers.

8. What if my battery dies during the test?

You are responsible for ensuring your calculator is in working order, including having fresh batteries. Test proctors will not provide batteries. This is why bringing an approved backup calculator is recommended.
