Roughly 0.2% to 0.5% of ACT test takers earn a Composite 36 in a given year—on the order of a few thousand students nationwide out of more than a million sittings—not the majority of strong testers. A 36 is rare by design; most high achievers land in the low 30s.
How rare is a Composite 36?
National data consistently places Composite 36 in the 99th percentile and above—often cited as the 99.5th percentile or higher. That means well under one half of one percent of test takers hit a perfect Composite in a typical year. Section 36s are slightly more common than a full Composite 36 because you can miss a question or two on one section and still round up—see how many questions you can miss for a 36.
Section 36 vs Composite 36
More students earn a 36 on a single section than on all three core sections in one sitting (or across a superscore). A student with 36/34/33 might have a strong profile but still fall short of a Composite 36 because of rounding. That is why "perfect scorer" lists often mix Composite 36s with students who peaked on one or two sections.
What this means for your goals
- A 34 or 35 already puts you in elite national territory—see ACT percentiles explained.
- Most selective colleges admit plenty of students without a 36—see ACT scores for Ivy League.
- Chasing 36 when a 32–34 meets your list's ranges may not be worth months of marginal gains. Target setting: how to find your target ACT score.
State and school context
A 36 is rare everywhere, but average scores vary by state—students in higher-average states see more 30+ scores simply because more students test and prep intensively. Compare broadly in ACT scores by state, not just your high school hallway.

The bottom line
A Composite 36 is a national rarity—not a requirement for top colleges. Use percentile context to calibrate ambition, and invest retake energy where your target schools actually see gaps.
Start practicing
Start with a free diagnostic, then drill your weak spots with 15-question quizzes and track how you're doing across Reading, English, and Math. Compare plans whenever you're ready to go further.
