Is it lower than instate?
Google is your friend. These stats are from 2015 so 2016 acceptance rate of OOS will probably be lower. Mandated reduction in OOS acceptances which required increase enrollment of in-state applicants will change these numbers.
Also OOS applicants no longer get financial aid so expect to be full pay at $55K/year to attend.
The OOS acceptance rate for out-of-state students for the class of 2020 was 12.9%. Contrast this to the acceptance rate of in-state students, which was 18.3%.
