Federal data, not an estimate: the middle 50% of Illinois State University's enrolled students and what to do with it.
By PrepScore · Updated · How we research and update content
The middle 50% of enrolled students at Illinois State University scored 990–1210 on the SAT — Reading and Writing 500–620, Math 490–590 — per the U.S. Department of Education's College Scorecard. A score at or above 1210 clears the band entirely; inside it, the upper half is the safer target. Illinois State University admits about 88% of applicants, so the score is one input among several, not a cutoff.
| 25th percentile | 75th percentile | |
|---|---|---|
| SAT total | 990 | 1210 |
| Reading and Writing | 500 | 620 |
| Math | 490 | 590 |
A middle 50% means a quarter of enrolled students scored below 990 and a quarter scored above 1210. It is a description of who enrolled, not an admission rule — people are admitted from below the band every cycle, and rejected from above it.
Federal data reports the students who enrolled. Admitted-student bands run slightly higher at most schools, because some of the strongest admits enrol elsewhere. Treat the band as a floor for planning, not a ceiling.

Work by section, not by mixed test. If Math is the weaker section, the Math domain pages split it into the skills the test actually samples; same for Reading and Writing. The method is set out in how to improve your SAT Math score and Reading and Writing.

The middle 50% of enrolled students scored 990–1210. A score in the upper half of that band is competitive, and 1210+ clears it entirely. There is no published cutoff.
A quarter of enrolled students did. Below the 25th percentile the rest of the application has to carry more weight, and a retake pays off most in this position.
Yes — 1210 is the 75th percentile of enrolled students, so it is above three quarters of the class. Past that point, more points buy little.
