Score Profile Visualization

This chart represents your scaled scores (1-36) across the four sections.

Formula Used: Composite Score = (Scaled English + Scaled Math + Scaled Reading + Scaled Science) / 4. Scaled scores are estimated based on historical raw-to-scale conversion curves.

What is “Can You Use a Calculator During the ACT”?

The question “can you use a calculator during the act” is one of the most common inquiries from high school students preparing for college admissions. To be precise, the ACT (American College Testing) permits the use of calculators only during the Mathematics section of the exam. This section consists of 60 questions to be answered in 60 minutes. While “can you use a calculator during the act” is a yes for math, the use of calculators is strictly prohibited in the English, Reading, and Science sections.

Who should use this calculator? Any student aiming to benchmark their current performance or understand how their raw score (the total number of correct answers) impacts their final composite score. Misconceptions often arise regarding which models are allowed. While most graphing calculators like the TI-84 are acceptable, any model with built-in Computer Algebra Systems (CAS) is generally banned.

Can You Use a Calculator During the ACT Formula and Mathematical Explanation

The conversion of your raw effort into a 1-36 score involves a statistical process called equating. This ensures that scores are comparable across different test dates. The basic mathematical steps are as follows:

  1. Calculate Raw Score: Sum of all correct answers in a section.
  2. Map to Scaled Score: Use a section-specific table to convert raw (e.g., 45/60) to scaled (e.g., 29/36).
  3. Average: Sum the four scaled scores and divide by four.
  4. Round: Round the result to the nearest whole number.
Variable Meaning Unit Typical Range
Raw Score (R) Total correct answers per section Count 0 – 75
Scaled Score (S) Standardized ACT metric Points 1 – 36
Composite (C) Final average of all four sections Points 1 – 36
Efficiency (E) Time spent per question Seconds 36s – 60s

Practical Examples (Real-World Use Cases)

Example 1: The STEM-Focused Student
A student excels in Math and Science but struggles with speed in English. They score a raw 58 in Math (Scaled 35) using a permitted TI-84 calculator. In English, they score a raw 50 (Scaled 24). Reading raw is 32 (Scaled 29) and Science raw is 35 (Scaled 32).
Calculation: (35 + 24 + 29 + 32) / 4 = 30 Composite. This shows that despite high math proficiency, “can you use a calculator during the act” math scores only account for 25% of the total.

Example 2: The Humanities Student
A student who focuses on Reading and English. Raw English: 70 (Scaled 35), Raw Math: 30 (Scaled 20), Raw Reading: 38 (Scaled 35), Raw Science: 30 (Scaled 27).
Calculation: (35 + 20 + 35 + 27) / 4 = 29.25, rounded to a 29 Composite score.

How to Use This Calculator

To determine your potential performance and address the query “can you use a calculator during the act”, follow these steps:

  • Step 1: Take a practice ACT exam under timed conditions.
  • Step 2: Grade your test and find the raw number of correct answers for each of the four sections.
  • Step 3: Enter these raw counts into the input fields above.
  • Step 4: Review the “Estimated Composite Score” to see your predicted ranking.
  • Step 5: Observe the “Secs per Math Question” to evaluate if your calculator use is efficient enough to finish the 60 questions in time.

Key Factors That Affect ACT Results

When asking “can you use a calculator during the act”, consider these critical factors that influence your final score:

  • Calculator Type: Using a TI-84 vs a basic four-function calculator can save minutes on complex graphing problems.
  • Battery Life: A dead battery mid-test can result in a significant score drop. Always bring spares.
  • Raw Score Curve: Every test date has a slightly different difficulty, affecting how raw scores map to scaled scores.
  • Speed vs. Accuracy: Rushing to use a calculator for simple arithmetic (like 7×8) can actually slow you down.
  • Memory Clearing: Proctors often require you to clear your calculator’s RAM, which removes stored programs or notes.
  • Familiarity: Using a brand-new calculator on test day is a recipe for disaster; use the tool you practiced with.

Frequently Asked Questions (FAQ)

Can you use a calculator during the act science section?

No, calculators are strictly prohibited during the Science section. You must rely on data interpretation and basic mental math.

Is the TI-Nspire CAS allowed?

No. Any calculator with Computer Algebra System (CAS) functionality is banned. The non-CAS version of the TI-Nspire is allowed.

Can I bring a backup calculator?

Yes, you can bring a backup, but it must stay on the floor under your desk unless your primary device fails.

What happens if I use a calculator in the Reading section?

You will be disqualified and your scores will be cancelled. “Can you use a calculator during the act” only applies to math.

Do I need a graphing calculator for a high score?

Not necessarily, but it is highly recommended for time-saving on coordinate geometry and functions.

Can I use a calculator on my phone?

Absolutely not. All mobile phones and wearable technology are strictly prohibited in the testing room.

Are there any specific “banned” brands?

It’s based on features, not brands. Most TI, Casio, and HP models are fine unless they have CAS or qwerty keyboards.

Does the ACT provide calculators?

No. You must bring your own permitted device to the testing center.
