Can You Use a Calculator on the ACT Science Test?
ACT Science Calculator Permissibility Checker
According to the official ACT policy, you are NOT permitted to use a calculator on the Science, Reading, or English sections. Calculators are only allowed on the mathematics test. However, understanding the general calculator rules is crucial. This tool helps you determine if a specific calculator would be allowed on the ACT Math test, which informs the overall testing policy.
Yes
CAS calculators can manipulate algebraic expressions symbolically (e.g., TI-89, TI-Nspire CAS).
Yes
Calculators with typewriter-like keyboards are prohibited.

Any device with internet or wireless communication capabilities is not allowed.
Yes
You cannot use the calculator on your phone or any other smart device.
Yes
Only battery-operated calculators are permitted in the testing room.
Permissibility Status for ACT Math Test
This reflects the rules for the Math test, which are the basis for ACT’s hardware policies.
Answering the Core Question: Can You Use a Calculator on ACT Science?
The answer from the official ACT governing body is unequivocally **no**. You are not permitted to use a calculator during the reading, science, or English sections of the ACT. The only section where a handheld calculator is allowed is the ACT Mathematics test. While all math problems can technically be solved without a calculator, it is a significant disadvantage not to use one on the math section. For the science section, however, you must rely on your ability to interpret data and perform mental calculations.
This policy ensures a level playing field, as the ACT Science test is designed to measure your scientific reasoning and data interpretation skills, not your ability to perform complex calculations. Therefore, when people ask “can you use a calculator on ACT science,” they are often trying to understand the test’s broader hardware limitations. The rules for the Math test dictate what kind of devices are allowed in the testing room at all.
ACT Calculator Policy Explained
The official ACT calculator policy is designed to ensure fairness and test security. For the Math test, you may use almost any four-function, scientific, or graphing calculator as long as it is not on the prohibited list. The primary restrictions are against devices that can communicate with other devices, access the internet, or store complex programs and notes.
Even though you can’t use it on the science section, knowing if your calculator is permitted for the math section is vital. If you bring a prohibited device, it may be confiscated, and you could be dismissed from the test.
Prohibited vs. Permitted Features Summary
This table summarizes what makes a calculator allowed or disallowed for the ACT Math test. Understanding this is key to the question “can you use a calculator on ACT science,” as a prohibited calculator isn’t allowed in the room at all.
| Feature | Status | Reasoning & Explanation |
|---|---|---|
| Basic Arithmetic (4-Function) | Permitted | Standard functionality for basic calculations. |
| Scientific Functions (sin, cos, log) | Permitted | Allowed for more complex math problems. Most scientific calculators are fine. |
| Graphing Capabilities | Permitted | Graphing calculators like the TI-84 series are explicitly allowed. |
| Computer Algebra System (CAS) | Prohibited | Calculators that can solve algebraic equations symbolically (e.g., TI-89, HP Prime) are banned. |
| QWERTY Keyboard | Prohibited | Considered a communication device and not allowed. |
| Wireless/Internet Access | Prohibited | Prevents cheating and access to external information. |
| Part of a Phone/Tablet/Laptop | Prohibited | Smart devices are strictly forbidden during the exam. |
Practical Examples
Example 1: A Permitted Calculator (TI-84 Plus)
A student brings a standard TI-84 Plus to the test center. During check-in for the math portion, the proctor inspects it. It does not have a CAS, no QWERTY keyboard, and no wireless features. This calculator is deemed **permitted** for the Math test. The student will use it for the math section and then put it away as instructed for the English, Reading, and Science sections.
Example 2: A Prohibited Calculator (TI-Nspire CX II CAS)
Another student brings a TI-Nspire CX II CAS. The “CAS” in the name stands for Computer Algebra System, which is explicitly on the prohibited list. The proctor identifies this and informs the student they cannot use this device. If the student has no backup, they must take the math test without a calculator, putting them at a severe disadvantage.
How to Prepare for the ACT Science Section Without a Calculator
Since the answer to “can you use a calculator on ACT science” is no, your preparation should focus on skills that don’t require one. The ACT Science section tests your ability to read graphs, understand experimental setups, and compare scientific viewpoints.
- Focus on Reading Data: Practice reading charts, graphs, and tables quickly and accurately. The answer is almost always in the data provided.
- Understand Experimental Design: Identify variables (independent, dependent, control) and the purpose of each experiment described.
- Practice Mental Math: The calculations required are typically simple arithmetic—differences, averages, or identifying trends (increasing/decreasing). You don’t need a calculator for these.
- Time Management: With about 5 minutes per passage, you need to work efficiently. Don’t get bogged down in complex details; find the main point and locate the data related to the question.
Key Factors for Success in ACT Science
Your success on this section, given you can’t use a calculator on ACT science, depends on several key reasoning skills:
- Data Interpretation: Can you look at a scatterplot and determine the relationship between variables? This is far more important than calculation.
- Trend Analysis: Identifying if a value is increasing, decreasing, or staying the same is a common question type.
- Scientific Vocabulary: Knowing terms like “hypothesis,” “control group,” and “variable” is essential.
- Passage Strategy: Many experts recommend skipping straight to the questions and referring back to the passage and figures to find answers, rather than reading the entire passage first.
- Comparing Viewpoints: The “Conflicting Viewpoints” passage tests your ability to understand and compare different scientific arguments.
- Outside Knowledge: While most answers are in the passages, 3-4 questions per test may require basic, foundational scientific knowledge.
Frequently Asked Questions (FAQ)
1. So, to be clear, can you use a calculator on ACT science at all?
No. The ACT policy explicitly states that calculators are not permitted on the Science, Reading, or English sections. They are only allowed for the Math test.
2. Why is there a calculator policy if I can’t use it on most of the test?
The policy exists to regulate the Math test and ensure no prohibited devices enter the testing room at all. A calculator with a QWERTY keyboard, for example, is a security risk regardless of the section.
3. What is the best calculator for the ACT?
For the Math section, a familiar graphing calculator like the TI-84 Plus or a scientific calculator like the TI-30XS is a great choice. The most important factor is your familiarity with it.
4. What happens if I’m caught using a calculator on the science section?
You would likely be dismissed from the test, and your scores would be invalidated for prohibited behavior.
5. Do I need to do complex math in the ACT Science section?
No. The math is typically limited to simple arithmetic, estimation, and interpreting numbers from graphs. The challenge is in the scientific reasoning, not the calculation.
6. Does the digital ACT have a built-in calculator?
Yes, for the Math test, the computer-based ACT includes an on-screen calculator. However, this calculator will not be available during the Science section.
7. Can I use a calculator on the ACT WorkKeys Applied Math test?
Yes, the calculator policy that applies to the ACT Math test also applies to the WorkKeys Applied Math test.
8. Where can I find the official, most up-to-date ACT calculator policy?
You should always refer to the official ACT website (act.org) for the latest version of the calculator policy before test day.
