Bachelor Of Science In Nursing

I will graduate in three years with a Bachelor of Science in Nursing (University of Texas). I was thinking lately about getting PT, and some more information on training. I know grad school is necessary, but that is where my knowledge ends. I prefer not to transfer from UT, but I can if needed. I would like to know what graduate schools will look at what certification grad school gives me what I need to change my current job, if any, ect.Thank in advance for your help!
