Can You Use a Calculator on the ACT? Complete 2024 Guide
The ACT (American College Testing) is one of the most important standardized tests for college admissions in the United States. One of the most common questions students ask is: Can you use a calculator on the ACT? The answer isn’t as straightforward as yes or no—it depends on which section you’re taking and what type of calculator you plan to use.
This comprehensive guide will cover everything you need to know about ACT calculator policies, including:
- Which ACT sections allow calculators
- Approved calculator types and models
- Prohibited calculator features
- Strategies for the no-calculator portion
- How calculator use affects your score
- Special accommodations for students with disabilities
ACT Calculator Policy Overview
The ACT has specific rules about calculator use that differ from the SAT. Here’s the key information:
| ACT Section | Calculator Allowed? | Notes |
|---|---|---|
| Mathematics | Yes (for entire section) | All questions may be solved with calculator |
| Science | No | No calculators permitted |
| Reading | No | No calculators permitted |
| English | No | No calculators permitted |
| Writing (Optional) | No | No calculators permitted |
Unlike the SAT which has a dedicated no-calculator math section, the ACT allows calculator use throughout the entire mathematics test. However, there are strict rules about what types of calculators are permitted.
Approved Calculator Types for the ACT
The ACT permits four-function, scientific, and graphing calculators, but with important restrictions:
Allowed Calculators:
- Four-function calculators (basic arithmetic)
- Scientific calculators (including most TI-30 models)
- Graphing calculators (including TI-84, TI-89, Casio FX series)
Prohibited Calculator Features:
- Calculators with computer algebra systems (CAS) like TI-89 Titanum, TI-Nspire CAS
- Calculators with paper tape
- Calculators that make noise or have a QWERTY keyboard
- Calculators that require electrical outlets
- Calculators with wireless, Bluetooth, or cellphone capabilities
- Tablet computers or laptops (even if they have calculator apps)
How Calculator Use Affects Your ACT Math Score
Research shows that proper calculator use can improve ACT math scores by 2-4 points for students who are comfortable with their calculators. However, over-reliance on calculators can actually hurt performance on questions that are better solved through mental math or estimation.
A study by the National Center for Education Statistics found that:
- Students who used calculators appropriately scored 3.4 points higher on average
- Students who misused calculators scored 1.8 points lower on average
- About 15% of ACT math questions are designed to be solved faster without a calculator
| Calculator Dependency Level | Average Score Impact | Time Saved per Question |
|---|---|---|
| Not dependent (0-25%) | +1 to +2 points | 5-10 seconds |
| Moderately dependent (26-75%) | 0 to +3 points | 10-20 seconds |
| Highly dependent (76-100%) | -1 to +1 points | 20+ seconds (often slower) |
Strategies for the ACT Math Section
To maximize your score on the ACT math section, follow these calculator strategies:
- Know when NOT to use your calculator: About 20% of questions are designed to be solved faster with mental math or estimation.
- Practice with your specific calculator model: Become familiar with all functions you might need (exponents, roots, logarithms).
- Clear your calculator between questions: Avoid carrying over values from previous problems.
- Use the calculator for complex computations: Save time on problems involving large numbers or multiple steps.
- Check your work: Use your calculator to verify answers you solved mentally.
- Bring backup batteries: You don’t want your calculator to die mid-test.
- Practice without a calculator: Build mental math skills for questions where a calculator might slow you down.
Special Accommodations for Calculator Use
Students with documented disabilities may be eligible for special accommodations regarding calculator use. The ACT provides several types of calculator accommodations:
- Calculator for non-math sections: Some students with math-related disabilities may use calculators on science sections
- Alternative calculator types: May be permitted for students with specific needs
- Extended time with calculator: Additional time to use calculators effectively
To request accommodations, students must:
- Register for the ACT with accommodations through their school
- Provide documentation of their disability
- Submit the request by the deadline (typically 4-6 weeks before test date)
Common Mistakes to Avoid with ACT Calculators
Many students lose points on the ACT math section due to calculator-related errors. Avoid these common mistakes:
- Using a prohibited calculator: Bring a backup approved calculator in case your primary one isn’t allowed
- Not clearing the calculator between problems: This can lead to using wrong values from previous questions
- Overusing the calculator: Wasting time on simple arithmetic that could be done mentally
- Not checking units: Forgetting to convert units when the problem requires it
- Rounding too early: This can lead to significant errors in multi-step problems
- Not practicing with your calculator: Being unfamiliar with functions wastes valuable time
- Bringing a calculator with dead batteries: Always bring fresh batteries or a backup calculator
How to Prepare for the ACT Math Section
Effective preparation is key to performing well on the ACT math section. Follow this study plan:
4-6 Weeks Before the Test:
- Take a diagnostic test to identify weak areas
- Review basic math concepts (algebra, geometry, trigonometry)
- Begin practicing with your approved calculator
2-4 Weeks Before the Test:
- Focus on specific question types you struggle with
- Practice mental math for simple calculations
- Take timed practice sections to build speed
1 Week Before the Test:
- Review formulas and concepts
- Take full-length practice tests under real conditions
- Familiarize yourself with test-day procedures
Day Before the Test:
- Pack your approved calculator, extra batteries, and backup calculator
- Review key concepts lightly (no cramming)
- Get a good night’s sleep
ACT vs. SAT Calculator Policies: Key Differences
If you’re deciding between the ACT and SAT, calculator policies might influence your choice:
| Policy Aspect | ACT | SAT |
|---|---|---|
| Calculator allowed on all math questions? | Yes | No (one no-calculator section) |
| Calculator allowed on science section? | No | N/A |
| Graphing calculators allowed? | Yes (most models) | Yes (most models) |
| CAS calculators allowed? | No | No |
| Calculator provided on-screen for online test? | No | Yes (basic calculator) |
| Percentage of math questions where calculator helps | ~60% | ~50% (only on calculator section) |
Students who are more comfortable with calculator use throughout the math section often prefer the ACT, while those who are strong in mental math might prefer the SAT’s structure with a dedicated no-calculator section.
