What is the ACT Calculator Policy?
Many students wonder, “can you use a calculator on the ACT science test?” The answer is simple and strict: No. According to the official ACT calculator policy, calculators are only permitted during the Mathematics Test. They are strictly forbidden for use on the Science, Reading, English, and Writing sections of the exam.
This policy is in place to ensure fairness and to test the intended skills for each section. While the Mathematics test assesses your ability to solve complex problems, where a calculator can be a useful tool, the other sections test different abilities. For example, the Science section is not a test of your calculation skills; it’s a test of your scientific reasoning and data interpretation abilities.
Why Can’t You Use a Calculator on the ACT Science Section?
The core reason you cannot use a calculator on the ACT Science test is that it’s designed to measure your scientific reasoning skills, not your mathematical computation abilities. The test presents you with passages, charts, and graphs and asks you to interpret data, evaluate experiments, and understand scientific concepts.
The math required for the Science section is intentionally basic, usually limited to simple arithmetic (addition, subtraction, multiplication, division), reading values from a graph, or identifying trends. A calculator would not provide a significant advantage and would detract from the section’s purpose. The policy ensures that a student’s score reflects their ability to think like a scientist, not their ability to punch numbers into a machine.

Practical Examples
Example 1: Student Taking the Mathematics Test
- Inputs: Student selects “Mathematics” in the calculator.
- Units: The test section is the unit of evaluation.
- Results: The tool shows “Permitted (With Restrictions).” The student knows they can use their approved TI-84 Plus graphing calculator for this portion of the exam.
Example 2: Student Taking the Science Test
- Inputs: Student selects “Science” in the calculator.
- Units: The test section is the unit of evaluation.
- Results: The tool shows “Prohibited.” The student understands they must put their calculator away before the Science section begins, confirming the rule for can you use a calculator on the act science.
How to Use This ACT Section Calculator
This tool provides a quick and easy way to verify the calculator policy for any section of the ACT.
- Select the Section: Click the dropdown menu labeled “Which ACT test section are you taking?”.
- Choose Your Section: Select Mathematics, Science, Reading, English, or Writing from the list.
- Interpret the Results: The result box will immediately update to show whether a calculator is allowed for that specific section. A green box means “Permitted,” and a red box means “Prohibited.” The explanation provides more context on the official rule.
Key Factors That Affect Calculator Use on the ACT
Understanding the full scope of the ACT’s calculator policy is crucial. Here are the key factors that determine if and how you can use a calculator.
| Factor | Meaning | Unit / Type | Typical Range |
|---|---|---|---|
| Test Section | The specific part of the ACT exam being administered. | Categorical | Math, Science, Reading, English, Writing |
| Calculator Functionality | The features built into the calculator, which are only relevant for the Math test. | Boolean (Allowed/Prohibited) | Prohibited features include Computer Algebra Systems (CAS), QWERTY keyboards, and wireless communication. |
| Calculator Model | The specific make and model of the device (e.g., TI-84 Plus). | Text | Models like the TI-89 and TI-Nspire CAS are explicitly banned. |
| Programs/Documents | Stored programs or files on a graphing calculator. | Boolean (Allowed/Prohibited) | All programs with CAS functionality and documents must be removed before the test. |
| Physical Modifications | Covering infrared ports or removing paper tape. | Action Required | Required for certain older models to be compliant. |
| Power Source | Calculators must be battery-powered. | Requirement | Devices that need to be plugged into an outlet are prohibited. |
Frequently Asked Questions (FAQ)
1. So, can you use a calculator on the ACT science section at all?
No, you absolutely cannot. Calculators are strictly prohibited during the ACT Science test. The test is designed to be completed without one.
2. What about the ACT Math test? What calculators are allowed?
For the Math test, you can use most four-function, scientific, and graphing calculators. The main restrictions are on models with Computer Algebra Systems (CAS), like the TI-89 or TI-Nspire CAS. A great resource for this is our guide on {related_keywords}.
3. Is my TI-84 Plus graphing calculator okay for the ACT?
Yes, the TI-84 Plus series (including the CE) is one of the most popular and widely accepted calculators for the ACT Mathematics test.
4. What happens if I’m caught using a calculator on the Science section?
Using a calculator on a non-permitted section is a form of prohibited behavior. You would likely be dismissed from the test, and your scores would be voided.
5. Why is the policy so strict?
The policy exists to ensure a level playing field for all test-takers and to make sure the test accurately measures the intended skills for each section (e.g., scientific reasoning vs. calculation).
6. What kind of math is on the ACT Science test if I can’t use a calculator?
The math is very basic. You might need to read values from a chart, find a difference between two numbers, or identify a trend (e.g., as one value increases, another decreases). It does not require complex calculations.
7. Where can I find the official, most up-to-date list of prohibited calculators?
The official ACT website is the definitive source. They maintain a page dedicated to the {primary_keyword} and list all specific rules and prohibited models. It’s wise to check it before test day. See our list of {internal_links} for more.
8. Are scientific calculators allowed?
Yes, scientific calculators are allowed on the ACT Math test. Many students prefer them. However, like all other calculators, they are not permitted on the Science section.
