Understanding the ACT Calculator Policy for the Science Section

A common question among students is, “can you use calculators on act science section?”. The short answer is yes, you can. The official ACT calculator policy is the same for all sections of the test where a calculator is permitted, including the Math test. However, while technically allowed, the utility of a calculator on the Science section is very different from its role on the Math test. Most Science questions are designed to test reading comprehension of charts, graphs, and experimental setups, not complex calculation skills.

The key is ensuring the calculator you bring is compliant with the ACT calculator policy. Using a prohibited device can lead to dismissal from the test center. This guide and the checker above will help you determine if your device is test-day ready.

The Official ACT Calculator Rules (Not a Formula)

Unlike a math problem, the “formula” for whether a calculator is allowed is a set of rules. Your calculator is generally permitted if it is a standard four-function, scientific, or graphing calculator. However, it is prohibited if it has any of the features listed in the table below.

Prohibited Calculator Features

Feature	Meaning	Typical Examples
Computer Algebra System (CAS)	Functionality that can manipulate algebraic expressions symbolically.	TI-89, TI-92, TI-Nspire CAS, HP Prime
QWERTY Keyboard	A keyboard laid out like a computer/typewriter.	Calculators with this specific layout are banned.
Communication Capabilities	Any device with Wi-Fi, Bluetooth, cellular, or other communication tech.	Smartphones, tablets, laptops, smartwatches
External Power Requirement	Device needs to be plugged into a wall outlet to function.	Calculators with power cords.
Noise or Tapes	Makes audible sounds or prints to a paper tape.	Must be modified (sound muted, tape removed).

Practical Examples of Permitted and Prohibited Calculators

Example 1: Permitted Calculator

• Device: Texas Instruments TI-84 Plus CE
• Inputs: No CAS, no QWERTY keyboard, no communication features.
• Result: PERMITTED. This is one of the most popular and widely accepted calculators for the ACT.

Example 2: Prohibited Calculator

• Device: An Apple iPhone with a calculator app.
• Inputs: Has wireless and cellular communication capabilities.
• Result: PROHIBITED. All smartphones, regardless of the app used, are strictly banned.

Key Factors That Affect Your Calculator on Test Day

• Proctor’s Discretion: The test proctor has the final say. If they deem a calculator suspicious, they can disallow it.
• Battery Life: You are responsible for your calculator’s power. Bring extra batteries or a backup calculator just in case.
• Familiarity: Bring a calculator you are comfortable with. Test day is not the time to learn a new device. Knowing your device is crucial for the ACT math calculator section.
• Programs and Data: You must clear any stored programs or documents, especially those with CAS functionality.
• Required Modifications: If your calculator makes noise, you must mute it. If it has an infrared data port, you must cover it with opaque tape.
• No Sharing: Sharing calculators with other test-takers is strictly prohibited during the exam.

Frequently Asked Questions (FAQ)

1. So, can I use a calculator on the ACT Science section?

Yes. The same calculators allowed on the Math section are allowed on the Science section. However, you will find it much less useful, as the section requires more reading and data interpretation than calculation.

2. Are all scientific calculators allowed on the ACT?

Yes, virtually all standard scientific calculators are permitted. Models like the TI-30XS MultiView are very popular. The only exceptions would be rare models with prohibited features like a QWERTY keyboard.

3. Is the TI-84 Plus allowed on the ACT?

Yes, all versions of the TI-83 and TI-84 Plus are allowed, as they do not have CAS functionality. They are among the most common permitted calculators for ACT.

4. What happens if I bring a banned calculator?

If you are found with a prohibited calculator during the test, you may be dismissed, and your test score will be voided. It is critical to check your device beforehand.

5. Do I really need a calculator for ACT Science?

No. All questions on the ACT, including the Science section, can be solved without a calculator. For the Science test, you might perform a simple addition or subtraction, which can easily be done by hand.

6. Can I use my phone as a calculator if it’s in airplane mode?

No. All phones, tablets, and other communication devices are banned, regardless of their mode or settings.

7. What about calculators with memory or program functions?

You can use them, but you are required to clear any stored programs that have CAS functionality. Proctors may check your calculator’s memory.

8. Is there an on-screen calculator for the computer-based ACT?

For the digital ACT, an on-screen calculator (Desmos) is provided. You are still allowed to bring your own approved handheld calculator if you prefer.
