The first step is to find a nursing program in your area. Here are some places to look!
Petersons has a specific search for nursing programs, or you can order the Nursing Programs Guide there. Choose "College Bound," then "Nursing" from the left hand menu.
Discovernursing.com has a good list of nursing programs, including graduate and vocational programs.
AllNursingSchools.com probably has the most comprehensive list of schools out there, along with profiles of individual programs. Check it out!
