Harvard's middle 50% ACT composite for enrolled students is 34-36, with an average of 35. That makes Harvard one of the most test-selective universities in the country, tied with Columbia for the highest ACT floor among Ivy League schools.
As of April 2024, Harvard reinstated mandatory standardized testing after a four-year test-optional period. The ACT (or SAT) is now required for all applicants. This guide covers what you need to know about ACT expectations at Harvard.
Harvard ACT Score Data
Source: Harvard 2024-2025 Common Data Set, compiled by Compass Prep and GradGPT. Section scores from the 2023-2024 CDS (Class of 2027). Official CDS available at Harvard OIRA.
The key takeaway: Harvard's 25th percentile is 34. That means 25% of enrolled students scored below 34, but the vast majority scored 34, 35, or 36. If your ACT is below 34, your score is below the range of most admitted students.
How Harvard Uses ACT Scores
Harvard uses holistic admissions. The admissions office has stated: "The Admissions Committee does not have testing cutoffs for applicants." Testing is one academic factor alongside grades, course rigor, essays, recommendations, extracurricular activities, and personal qualities.
That said, with a 4.2% acceptance rate and nearly 48,000 applicants for the Class of 2029, the reality is that most admitted students have test scores at or above the 99th percentile. Your ACT score does not get you in, but a low score (relative to the applicant pool) can raise questions about academic preparation.
Harvard vs Other Ivy League Schools
Harvard and Columbia have the highest ACT floor (34) among all Ivies. Yale, Dartmouth, and Cornell start at 33. If you are applying to multiple Ivy League schools, a 34 puts you in range at all of them. For a broader comparison, see our guide to good ACT scores by college tier.
Does Harvard Superscore the ACT?
Harvard accepts ACT superscores. When you send your superscore, Harvard also receives the full results from your best single sitting. In practice, they review both numbers. This means taking the ACT multiple times can help, particularly if you can improve one section score while maintaining the others.
Tips for Reaching Harvard's ACT Range
- Target a 35. A 35 puts you at the median of Harvard's enrolled class. Aiming for 35 gives you a buffer if one section dips slightly on test day.
- Focus on your weakest section. Harvard's section data shows Math has the widest range (25th percentile is 33 vs. 35 for English). If you are strong in English and Reading but weaker in Math, that is where your prep time should go.
- Plan for 2-3 test dates. With superscoring, you can combine your best section scores across sittings. Use your first attempt as a diagnostic.
- Remember the holistic picture. Your ACT is one factor. Harvard's admissions FAQ explicitly states there are no testing cutoffs. A 33 with exceptional extracurriculars, a compelling essay, and strong recommendations is a stronger application than a 36 with nothing else.
