Federal data, not an estimate: the middle 50% of Rensselaer Polytechnic Institute'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 Rensselaer Polytechnic Institute scored 30–34 on the ACT Composite, per the U.S. Department of Education's College Scorecard. A Composite at or above 34 clears the band; inside it, aim for the upper half. The Composite is the average of English, Math and Reading, so the cheapest gain is always the weakest section. Rensselaer Polytechnic Institute admits about 63% of applicants — the score is one input, not a cutoff.
| 25th percentile | 75th percentile | |
|---|---|---|
| ACT Composite | 30 | 34 |
A middle 50% means a quarter of enrolled students scored below 30 and a quarter above 34. It describes who enrolled — it is not an admission rule.
It averages English, Math and Reading, rounded at the half. One raw question in your weakest section can move the Composite a full point — which makes the weakest section the cheapest place to gain. Science is optional and does not affect it.
Section-by-section ACT practice under the real clock, with an explanation on every question.
The middle 50% of enrolled students scored 30–34 on the Composite. The upper half of that band is competitive, and 34+ clears it. There is no published cutoff.
A quarter of enrolled students scored below 30. It is possible, and the rest of the application has to carry more weight.
