How do I become a nurse practitioner?

Diane is correct, you will need at least a year or more of work experience as an RN before any grad school will accept you to an NP program. What kind of NP are you interested in? Try to get at least a year of work experience in that specific area, for example, if you want to be a Pediatric NP, get a job in peds, it will be better on your application, shows you are dedicated to that specialty. You shouldn't rush into grad school anyway - you really should be sure the track you are choosing is the right one for you, because it would really suck to get part way through and decide you'd really rather be doing something else. Good luck!

Yes that is the exact path you would take to become one. Nurse practitioner programs are about 2 years in length. Some schools need the GRE to be taken, and you need a good gpa in your undergrad to be admitted.
