What is the ACT Calculator Policy?

The ACT Calculator Policy is a set of rules established by ACT, Inc. to define which calculators are allowed and prohibited during the ACT test. The primary purpose of this policy is to ensure a fair and equitable testing environment for all students, prevent academic dishonesty, and maintain the security of the test. The core principle is that calculators are tools for computation, not for storing information or solving problems through prohibited means. Therefore, the question of “can you use a basic calculator on the ACT” is a fundamental one, and the answer is yes, but it’s part of a much broader set of regulations.

These rules apply only to the Mathematics section of the test; calculators are not permitted on any other section. While all math problems on the ACT can technically be solved without a calculator, some calculations can be complex and time-consuming. Using an approved calculator efficiently can be a significant strategic advantage. The policy outlines prohibited features, lists specific banned models (like those with a Computer Algebra System), and explains modifications required for certain permitted calculators. Students are responsible for bringing their own approved, working calculator to the test center.

ACT Calculator Rules and Feature Explanation

Instead of a mathematical formula, the ACT policy is a logical one based on calculator features. The rule is simple: if a calculator has any single prohibited feature, it is not allowed. To determine if you can use a calculator on the ACT, you must verify it has none of the forbidden characteristics. Below is a breakdown of the key features and their status according to the ACT.

Permitted vs. Prohibited Calculator Features

Feature/Characteristic	Meaning	Status	Typical Range/Example
Four-Function	Performs basic arithmetic (add, subtract, multiply, divide).	Permitted	Any basic, simple calculator.
Scientific Functions	Handles logarithms, trigonometric functions, and exponents.	Permitted	TI-30X, Casio fx-115ES
Graphing Capability	Can plot equations on a coordinate plane.	Permitted	TI-83, TI-84 Plus series.
Computer Algebra System (CAS)	Manipulates algebraic expressions and solves equations symbolically.	Prohibited	TI-89, TI-Nspire CAS, HP Prime.
QWERTY Keyboard	A typewriter-style keyboard layout.	Prohibited	TI-92 Plus, HP-95LX
Wireless/Internet	Any device that can communicate externally (Wi-Fi, Bluetooth).	Prohibited	Smartphones, tablets, smartwatches.
Needs Power Cord	Requires being plugged into an electrical outlet to function.	Prohibited	Printing calculators, desktop models.
Makes Noise / Prints Tape	Has audible tones or a paper printing function.	Modification Required	Must be muted; tape must be removed.

Practical Examples (Real-World Use Cases)

Example 1: The Standard Graphing Calculator

A student wants to bring a Texas Instruments TI-84 Plus CE to the test. They use our checker:

• Is it a device? No.
• QWERTY Keyboard? No.
• Internet? No.
• CAS? No (this model does not have CAS).
• Power Cord? No.
• Noise/Tape? No.

The result is a clear “Permitted”. The TI-84 Plus CE is one of the most common and recommended calculators for the ACT, and this confirms it meets the policy. Knowing you can use this familiar calculator on the ACT is a great confidence booster.

Example 2: The Prohibited Advanced Calculator

Another student has a Texas Instruments TI-89 Titanium, a powerful calculator they use for advanced high school math classes. They run it through the checker:

• Is it a device? No.
• QWERTY Keyboard? No.
• Internet? No.
• CAS? Yes.

The moment they check “Yes” for the Computer Algebra System (CAS), the checker immediately returns “NOT Permitted”. The TI-89 is explicitly banned by the ACT because its CAS functionality provides an unfair advantage. This student now knows they need to find a different, compliant calculator for test day.

Key Factors That Affect Your Calculator Choice

Choosing the right calculator for the ACT involves more than just checking the rules. Several strategic factors can impact your performance. How you weigh these factors helps determine if you should use a basic calculator on the ACT or a more advanced one.

1. Familiarity and Speed

The best calculator is the one you know inside and out. The ACT is a timed test, and fumbling with an unfamiliar device can waste precious seconds. If you’ve used a TI-84 for two years, don’t switch to a new brand a week before the exam. Speed and accuracy with your chosen tool are paramount.

2. Your Personal Math Level

If you are in advanced math courses like calculus, a graphing calculator is likely second nature to you. Its ability to graph functions, find intersections, and run statistical analysis can be very helpful. However, if you are more comfortable with basic algebra, a simpler scientific or even a four-function calculator might be less distracting and perfectly adequate. You don’t need a graphing calculator to ace the test.

3. Graphing vs. Non-Graphing

Graphing calculators can be a powerful tool for solving problems related to coordinate geometry and functions. Visualizing a parabola or the intersection of two lines can be much faster than solving it algebraically. However, the vast majority of ACT math questions don’t require graphing. Decide if the potential time-savings on a few questions is worth it for you. Explore our advanced math strategies page for more.

4. The “No Calculator” Reality

A crucial point to remember is that every single question on the ACT Math test can be solved without a calculator. The test is designed this way. Over-reliance on a calculator can actually slow you down, especially on questions that are faster to solve with mental math or simple logic. Your primary skill should be math, with the calculator as a secondary tool.

5. Battery Life and Reliability

This is a simple but critical logistical factor. Ensure your calculator has fresh batteries or is fully charged before test day. Many students bring a backup calculator (and extra batteries) just in case. An identical backup is ideal so you don’t have to switch to an unfamiliar model mid-test.

6. Basic vs. Scientific Calculator

So, can you use a basic calculator on the act? Yes, absolutely. For many students, a simple scientific calculator (like a TI-30XS) is the perfect balance. It handles all the necessary operations—trigonometry, exponents, etc.—without the complexity of a graphing calculator. This often prevents you from getting bogged down in menus and focuses you on the math itself.

Frequently Asked Questions (FAQ)

1. What is the best calculator for the ACT?

There is no single “best” calculator; it’s the one you are most familiar and efficient with. For most students, the TI-84 Plus series is a popular and effective choice because it balances powerful graphing features with widespread use in high school classrooms. However, a scientific calculator like the TI-36X Pro is also an excellent, less-distracting option.

2. Can I use a TI-89 or TI-92 on the ACT?

No. Both the TI-89 and TI-92 series are explicitly prohibited because they contain a built-in Computer Algebra System (CAS). This feature can solve algebraic equations symbolically, which is against ACT policy.

3. Is the TI-Nspire allowed on the ACT?

It depends on the model. The standard TI-Nspire (non-CAS) and the TI-Nspire CX are permitted. The TI-Nspire CAS and TI-Nspire CX CAS are not allowed due to their CAS functionality. You must be careful to bring the correct version.

4. What happens if I bring a prohibited calculator to the test?

The testing staff will check calculators. If you are found with a prohibited model, you will not be allowed to use it. If you are caught using one during the test, you could be dismissed from the test center and have your score voided. It’s not worth the risk.

5. Do I need to clear my calculator’s memory?

The ACT requires that you remove any programs or documents that have CAS functionality. While proctors may not always check, the official policy requires it. It is a good practice to clear any non-essential programs or data to be safe.

6. Can you use a basic calculator on the ACT?

Yes, you can absolutely use a basic, four-function calculator on the ACT. It is fully permitted and can be used for all arithmetic. While it lacks advanced functions, it is sufficient to solve the problems, as no problem requires a calculator.

7. Can I share a calculator with another student?

No. Sharing calculators is strictly prohibited during the test. You must bring your own device. This is why having a reliable calculator with good batteries (or a backup) is so important.

8. Can I use my calculator on the Science section?

No. Calculator use is only permitted during the Mathematics section of the ACT. You may not have your calculator out during the Reading, English, or Science sections. For help on that section, see our Science reasoning tips.
