1. What is the ACT Score Percentile?

The ACT Score Percentile shows how your composite score compares to other test-takers. It represents the percentage of students who scored at or below your score.

2. How Does the Calculator Work?

The calculator uses the ACT Percentile equation:

Where:

• \( Per \) — Percentile estimate (%)
• \( CS \) — ACT composite score (1-36)

Explanation: This provides a simple estimate of your percentile based on the maximum possible ACT score.

3. Importance of Percentile Calculation

Details: Percentiles help colleges compare your performance with other applicants and understand your relative standing.

4. Using the Calculator

Tips: Enter your ACT composite score (1-36). The calculator will estimate your percentile ranking.

5. Frequently Asked Questions (FAQ)

Q1: Is this the official ACT percentile?
A: This is an estimate. Official percentiles vary slightly by testing year and population.

Q2: What's considered a good ACT percentile?
A: Generally, 75th percentile or above (score ≥27) is considered competitive for most colleges.

Q3: How often do ACT percentiles change?
A: Percentiles are updated annually but remain relatively stable year-to-year.

Q4: Does this calculator work for section scores?
A: No, this calculates percentiles for the composite score only.

Q5: Why is the maximum ACT score 36?
A: The ACT is scaled so that 36 represents the highest possible composite score across all four test sections.
