We had a personal statement but did not need references and this was a few years back. Acceptances were sent out mid to late April.
Securing clinical was always an issue. (Not the fault of the school) Hospitals, psych facilities, nursing homes, Pediatric skilled nursing care, etc depended on instructors, number of students, etc..
If anyone is put on a wait list, I suggest making an appointment with the admissions office to review your rubric. Believe me when I say they aren't perfect and occasionally make mistakes. (Miss a grade, or class) and that really affects your place on the wait list. I know this from personal experience. I was #10 on it and was going to give up. I just happened to have a day off and went down to discuss it. When they pulled up my application, they realized they missed 2 classes on my transcript that I had gotten an A in. It shot me to #1 on the list. They were extremely nice and very apologetic as they go through each app by hand.- Don't give up!
