Nursing school

The questions you are asking are very program specific. You need to find programs you're interested in and ask them if your credits would transfer, etc.

Finish your current ES degree and then apply to BSN schools as a second degree seeking student. Between now and being accepted, you will need to find out what pre-reqs Carrinton requires and finish them before being accepted. You may have already taken some of the pre-reqs during your ES education.

This step will take two years for the nursing program, plus however long it takes to complete the pre-reqs and wait for acceptance. You're likely looking at a 3 year process after finishing your ES degree.

I would highly suggest you meet with an advisor at the Carrington College nursing school and get the most accurate answer.

I disagree about finishing the ES degree first, it'll be a waste of time and money- 75 credits toward a bachelor's is only about 5 semesters through (average) and OP probably has completed only most of the general courses and maybe a semester in total of core courses.

Assuming you've completed all of your generals as you would in a typical Bachelor's program, your best bet would be to just go for your BSN. If you can't get into any BSN programs that you would want to attend, then I would look into Associate's programs as a last resort. I would look at your school's nursing program first, if it has one, and see what you need to do to be competitive to apply to that, or find another uni/college that will accept the credits you've completed. If you need to complete any other pre-reqs or generals before transferring programs, complete them in whatever way would be most effective for your time and money. All of the rest of the information we could help you with would be school specific, I think, so you'll need to look into what schools you would be interested in attending and compare their programs. Be sure to make an inquiry to the schools so they can give you an idea of what they require to apply to the nursing program, tuition costs, time required, how clinicals are set up, if you'll be able to work while in the program if needed, etc.

Nursing program hierarchy is set up like this:

ADN: Associate's in Nursing leading to RN certification

BSN: Bachelor's in Nursing leading to RN certification

ABSN: Bachelor's in Nursing leading to RN certification- accelerated program typically for applicants who have already completed a Bachelor's and pre-reqs

MSN / PhD: could lead to RN cert (pretty sure I've seen those mentioned around here before) but typically will be for those already practicing. These are for nurses who want to have more specialized knowledge (Nurse Midwife, CRNA, NP, APRN, etc.) in their field.

(Also I am currently getting out of a program that leads to a teaching certification and finally taking the plunge into nursing after 5 years of internal BS / anxiety about applying to nursing programs- the state of education is too precarious in the US right now; districts need teachers but don't have enough funding to support their staff, charter schools are opening and closing within months... just all kinds of things happening that I don't trust to support a good environment for my child's education let alone my career. Not that I really want to influence you toward either field, just be aware that education is going to continue changing and more responsibility will be placed on teachers with little benefit to the employee or students.)

You can either go straight into a BSN program from the get, or you can go from a 2 year ADN program and then take a BSN transition program after. If you want to go the really long route, you could even be an LPN, then an LPN-RN program, then an RN-BS program.

However, be wary of Carrington. It's a for profit school that charge a lot for courses that may not be transferable. Some due diligence is recommended on your part researching if Carrington is your best option.
