As far as schools go, you just have to look in your area. If you're looking for the cheapest alternative, an ADN through a community college will have you becoming an RN in half the time of a university. However, many big hospitals are starting to want their RNs to have bachelor's degrees. The plus side is many universities have programs that allow people with their ADN to get a BSN pretty quickly and many hospitals will pay for their employees to get it, so it ends up being very affordable!
If you have any other questions post them here and I will get back to you ASAP. Best of luck. Nursing is a wonderfully flexible, intelligent, interesting, and caring field. I've been working during this pandemic and I truly have never felt more proud.
First of all, you can congratulate yourself for researching one of the best professions around!
You will need to go to a college program that specifically grants you a nursing degree. In order to do this, you need a high school diploma or a GED.
Do an internet search for your local colleges (or not local if you are okay with relocating). I personally think that it is a good idea to start with some of the local community colleges and/or state schools. Most have very good nursing programs.
These schools will also have an admissions office that will tell you the requirements to get into their program. Most of the time they outline it on their website. They might also have an informational session.
Good luck and I hope this helps.
