I am a current NIU student who has applied to the nursing program for the fall 2016/spring 2017. From my knowledge, they take 100 per semester. 30-50% (from what I have read) are transfers. I was told the average G.P.A. of those accepted was typically a 3.7-4.0, but it varies from year to year. They also take into consideration how many pre-requisites you have completed (need a minimum of 5 to be considered)
