This isn't a correction - just a little more detailed answer.
The quickest route may have more to do with how "easy" it is to get into the various programs in your area. Several members on this site have stated that it was faster for them to get into a ADN (2 year) program, but almost as many have stated it was quicker for them to get into a BSN (4 year) program. And that really depends on how many students each school accepts - and whether they have only Fall entrance, or Fall & Spring entrances for their Nursing program.
As to a pay difference between ADN and BSN - that depends on the area you live in also. Here in the Dallas-Ft Worth area, the pay is either the same or 50 cents more per hour for BSN's. I've read many posts where nurses say the pay is roughly the same. Many (not all) nurses get their BSN because they want job security (every once in awhile there is talk about requiring a BSN), want to be in management, or they want to eventually get their MSN - either NP or MSN in Education.
I got my ADN, and I'm currently taking courses towards my BSN. Someday I'd like to have my MSN in Education so that I can teach when I retire from the bedside. And...I think I love going to school now! ha!:spin: It's really up to you - I think both programs can be great, and like people even two ADN or BSN programs aren't just alike. I'd say consider your life - whether you need to work, if you're married, have kids, etc. and go from there.
Good Luck & God Bless!
