What is the ACT Calculator List?
The act calculator list refers to the specific guidelines provided by ACT, Inc. regarding which electronic devices are permitted during the mathematics portion of the ACT exam. Unlike the SAT, the ACT has very specific restrictions on the types of calculators you can bring. Understanding this list is as crucial as knowing your subject matter, as bringing a prohibited device can lead to dismissal from the test center.
While our tool above helps you calculate your scores, the official act calculator list dictates the hardware you can use to solve math problems. Generally, most graphing calculators (like the TI-84 Plus) are allowed, but those with Computer Algebra Systems (CAS) like the TI-89 or TI-Nspire CAS are strictly prohibited. Always verify your device against the current year’s rules.
ACT Composite Score Formula and Mathematical Explanation
The ACT Composite Score is simply the average of your four section scores, rounded to the nearest whole number. Understanding the math behind the scoring can help you strategize. For instance, because of the rounding rule, you don’t need a perfect average to get a higher score.
The formula is:
Composite = (English + Math + Reading + Science) / 4
Standard rounding rules apply: any result ending in 0.5 or higher rounds up to the next whole number. This implies that a 29.5 becomes a 30.
| Variable | Meaning | Unit | Typical Range |
|---|---|---|---|
| English Score | Score on English section | Points | 1 – 36 |
| Math Score | Score on Math section | Points | 1 – 36 |
| Reading Score | Score on Reading section | Points | 1 – 36 |
| Science Score | Score on Science section | Points | 1 – 36 |
Practical Examples (Real-World Use Cases)
Example 1: The Round-Up Benefit
Sarah has strong language skills but struggles slightly with Science. She checks the act calculator list to ensure her calculator is allowed for Math, then scores the following:
- English: 30
- Math: 28
- Reading: 31
- Science: 27
Calculation: (30 + 28 + 31 + 27) = 116 points.
Average: 116 / 4 = 29.0.
Final Composite: 29.
Example 2: Leveraging the Half-Point
Jason wants to hit a composite of 24. He currently has:
- English: 22
- Math: 23
- Reading: 24
- Science: 25
Calculation: (22 + 23 + 24 + 25) = 94 points.
Average: 94 / 4 = 23.5.
Final Composite: 24.
Jason achieves his goal because the 23.5 rounds up to 24.
How to Use This ACT Calculator List & Score Tool
- Enter Section Scores: Input your actual or practice test scores into the four fields (English, Math, Reading, Science).
- Review the Composite: The large number at the top of the results is your estimated ACT composite score.
- Analyze the Chart: Look at the bar chart to see which sections are pulling your average down.
- Check “Points to Next”: This intermediate value tells you exactly how many more raw section points you need (across any subject) to bump your composite score up by 1 point.
- Consult the ACT Calculator List: Before your exam, use the links below to verify your physical calculator is permitted.
Key Factors That Affect Your ACT Results
Achieving a high score involves more than just studying. Several factors influence your final number:
- Calculator Policy Compliance: Familiarizing yourself with the act calculator list is vital. Bringing a prohibited calculator can result in your scores being cancelled.
- Time Management: The ACT is a speed-intensive test. Pacing yourself ensures you answer every question, which maximizes your total point input.
- Guessing Strategy: There is no penalty for wrong answers on the ACT. Never leave a bubble blank; statistically, guessing improves your raw score.
- Section Balance: Since the composite is a straight average, a very low score in one section (e.g., Science) can drastically pull down high scores in others.
- Test Anxiety: Nervousness can lead to simple arithmetic errors. Confidence in your tools (like knowing your calculator is on the approved act calculator list) helps reduce stress.
- Preparation Quality: Consistent practice with real prompts helps stabilize your section scores, making your composite prediction more accurate.
Frequently Asked Questions (FAQ)
Generally, calculators with CAS (Computer Algebra System) functionality, QWERTY keyboards, or wireless communication capabilities are prohibited. Examples include the TI-89 and TI-Nspire CAS.
No. The Writing (essay) score is reported separately and does not factor into the 1-36 composite score calculation used by most colleges.
Because the score is an average, every 4 additional points you earn across the four sections (e.g., +4 in Math, or +1 in each section) raises your average by exactly 1 point.
Yes, the TI-84 Plus family is generally permitted and is one of the most popular choices for the exam.
According to ACT rounding rules, a 29.5 rounds up to a 30. A 29.25 would round down to a 29.
No. Cell phones, tablets, and smartwatches are strictly prohibited and are not on the permitted act calculator list.
The ACT has four required sections: English, Math, Reading, and Science. All four carry equal weight in determining your composite score.
This tool uses the exact mathematical formula used by ACT, Inc. However, real exams involve equating procedures that adjust raw scores to scale scores differently per test version.
