This is actually a great question! I wish I had knew what to expect. You can wear casual clothes but because some of your professors may be there you may want to dress really nice and semi-professional (read: dressy top and dark jeans or slacks. No need for a suit or anything like that). Be sure to bring something to hold all the paperwork that you will receive, some paper to write notes, a pen and a planner to record important dates. This is important: be sure to introduce yourself to a few classmates and exchange emails. **This is important if you have a question about something. You can help each other out!**
Orientation is where they welcome new students and literally "orient" them to what the program will be like. They can be a couple of hours long or last all day- so be prepared. Because its nursing school, the main speaker (usually the Dean, Assistant Dean, or such) try to lay out what nursing school is going to be like. They may talk about registration requirements such as BLS/CPR, vaccinations, etc. They will probably discuss how to register for the first semester. They will go over uniform
guidelines and give you a supply list. You may get a booklist for your first semester, as well as the book list for all of your courses. Lastly they discuss all of the departments that you may need throughout the program such as Advisement, FinAid, Public Safety etc. Good Luck!!!
