How to Read an ACT Score Report
ACT score reports are available online about two to eight weeks after testing (the timing varies by administration). The report includes several layers of information beyond the composite score.
Composite Score (1–36)
The composite is the average of the four section scores, rounded to the nearest whole number. This is the primary score colleges use when reviewing ACT results. A composite of 21 is close to the national average.
Section Scores (1–36 each)
| Section | Scale | What It Covers |
|---|---|---|
| English | 1–36 | Grammar, punctuation, sentence structure, style |
| Mathematics | 1–36 | Pre-algebra through trigonometry and statistics |
| Reading | 1–36 | Comprehension of prose passages in four genres |
| Science | 1–36 | Data interpretation, research summaries, conflicting viewpoints |
Subscores
ACT also reports subscores within each section, ranging from 1–18, that identify performance in specific skill areas. For example, the English section breaks into “Production of Writing” and “Knowledge of Language” and “Conventions of Standard English.” These subscores are useful for targeted preparation before a retake.
Percentile Ranks
The score report shows a national percentile rank for the composite and for each section. The ACT also provides percentile ranks for college-intending seniors, which will differ slightly from the overall national norms.
College Readiness Benchmarks
ACT publishes college readiness benchmarks for each section:
| Section | College Readiness Benchmark |
|---|---|
| English | 18 |
| Mathematics | 22 |
| Reading | 22 |
| Science | 23 |
Meeting these benchmarks means there is a 75% or higher chance of earning at least a B in the corresponding college course. They are not admissions cutoffs.
Score Verification and Retesting
If any score seems unexpectedly low, families can request hand scoring for an additional fee. Many students take the ACT two or three times; the score typically improves modestly on the second attempt. Most colleges superscore or consider the highest composite across multiple sittings.
