I am a former student of DSN and a recent new grad. Any school is going to have good and bad points, and I really think it is what you put into it. It is true the NCLEX pass rate for 2015 is not good as reported on the DORA website. Since I can only speak for myself, here it goes. I did have an OB rotation at Denver Health and other clinicals at other hospitals. The majority of my cohort passed their board exams on the first try and now have hospital positions throughout Denver and in other states - UCH, Children's, Swedish, Denver Health, Medical Center of Aurora, Porter, Rose, Lutheran, SJH just to name a few. In addition, I was selected, along with other DSN new grads, for a competitive SCL new grad residency program.
There are no perfect programs. I would recommend getting information about all the programs you are interested in and seeing which one works for you.
