What does the middle 50% mean?

Schools publish the 25th and 75th percentile SAT scores of admitted students. The middle 50% is the range between them — half of admitted students scored inside it. Landing above the 75th percentile means your test score is stronger than three-quarters of admits.

How is ACT converted to SAT?

The tool uses the official ACT-SAT concordance published by the College Board and ACT. For example, an ACT composite of 30 maps to roughly an SAT total of 1370. The conversion lets you compare an ACT score against an SAT percentile range.

Does being above the 75th percentile guarantee admission?

No. Test scores are one factor among many — GPA rigor, essays, extracurriculars and institutional priorities all matter. At highly selective schools, even applicants above the 75th percentile face low acceptance rates because the applicant pool is enormous.

Why does the acceptance rate matter if my scores are high?

The base acceptance rate caps your realistic odds. A 5% acceptance rate school rejects most applicants who are academically qualified, so strong scores keep you in contention but do not lift you near a coin flip. The tool frames odds relative to that base rate.

Where do I find a school's percentile data?

Each school's Common Data Set (section C9) lists the 25th and 75th percentile SAT and ACT scores of enrolled students, and acceptance rates are in section C1. College profile sites republish these figures. Use the most recent year available.

College acceptance GPA + SAT guide

Whether your stats are good enough depends entirely on the school. This tool compares your GPA and SAT total (or ACT composite, auto-converted) against a school’s published admitted- student percentiles and acceptance rate, then tells you whether you sit below, inside, or above the middle 50% — the single most useful admissions yardstick.

How it works

Colleges publish the 25th and 75th percentile SAT scores of admitted students. The span between them is the middle 50%:

Below the 25th — your test score is a weak spot; you’re in the bottom quarter of admits.
Within the range — your score is typical for the school.
Above the 75th — your score beats three-quarters of admitted students.

If you enter an ACT composite, the tool converts it to an SAT-equivalent using the official ACT-SAT concordance before comparing. Your standing is then framed against the school’s overall acceptance rate, which sets the ceiling on realistic odds.

Notes

Percentiles describe test scores only. GPA rigor, essays, recommendations and institutional priorities can move an application in either direction, and at very selective schools a low base acceptance rate means even above-75th applicants are frequently turned away. Pull the school’s figures from its Common Data Set (sections C1 and C9) for the most accurate comparison.
