You have your RN? You just don't have a BSN?
If you want to be an NP you need to first decide which type...family, peds (acute or primary), adult, neonatal.... You then need to look at schools that have the specialty you want...not all schools that have NP programs have all the specialities. Look at their requirements to get in. Do they require experience? Many, but not all, do. If you need experience...get it. It really isn't complicated.
If you don't have a BSN you have to decide i you want to do an RN to BSN and then move on or try and find an RN to MSN. An RN to MSN will be harder to find.
If you get an MSN in something that isn't associated with an NP program you can still become an NP. You then just look for a post master's certificate program. You will then just do the NP portion.
So you can get an MSN in education...then go back and do a post master's certificate in an NP program.
