While in-state enrollment is up, so is international student enrollment.
If you compare 2015 numbers with 2014, you’ll see that overall enrollment INCREASED. From 6,937 in 2014 to 7,565 in 2015. That’s how they increased in-state enrollment. In-state enrollment went from 71% to 72.6%, we’ll have to wait see if this is a trend, or if this is nothing more than a one time increase in enrollment.

On the ACT scores, keep in mind that since you apply to your major, the ranges of accepted ACT scores will also vary by major. Division of General Studies range is 25-30, while Engineering is 31 to 34. An overall ACT score of 28.28 doesn’t really tell us the whole story…
And did the ACT score drop because of an initiative to recruit more in-state students or simply as a result of increasing enrollment (to generate more tuition revenue and/or to placate the state legislature)?
