I see this as two different ways:
1) All of this is just a scare tactic so the school seems competitive. I am pretty sure the school will want to take in as many students as they can and are able to. I say this because if you look at classes for NUR 111 which would be the clinical classes as Jennifer has stated above, you see there are about more or less than 100 spots open for both the clinical and the lab classes for NUR 111. They would not lower the TEAS score unless they needed more of a turnout for students. From previous years postings on all nurses, you can see they accepted all eligible students that applied. They will keep accepting students up until they don't have any more space. Plus the traditional program is supposed to take in more students than the hybrid program. The hybrid program took about 80 sum students for fall 2015.
2) If you look for classes for Nursing 150, there is only one class with space for 46 students. Maybe they don't have another teacher to teach another session for NUR 150 or in the process of obtaining another teacher. Which could be why they said at first they would only accept about 20% of the students--roughly about 50ish students.
But then again I could totally be wrong for both ideas.
