Re: Why Bachelors over Associates?!? is it worth it?
This is NOT, repeat NOT an answer designed to say one RN is better than another. It is an attempt to answer the differences in the two programs, based on a curriculum development class I just finished.
The BSN vs. ADN is the breadth and depth of education.
The "3 year" vs. "4 year" degree is very deceptive. It is possible to get enough hours in one year for entry into an ADN program, but not easy. Prereqs tend to cover the basics needed for nursing, English, Biology, Anatomy. Adds up to 90+ hours altogether, for graduation.
BSN curricula usually demand a least 60 hours of prereqs just to get in. (Not talking the bridge ones, didn't study those as hard

). The courses cover much more science than the ADN, as well as a lot of humanities courses, which is why its a Bachelors (something from every area of study). Some require political science, organic as well as basic chemistry, more than one psych class, philosophy, and general humanities classes, etc. The nursing courses include research, leadership & management, dedicated courses to public health nursing (6 hours, not as part of general nursing courses) and more. There are 66+ hours of upper level nursing courses alone, in many cases; nearly impossible to finish in 2 years, most BSN programs that I know of are 5 semesters, you WILL do the summer course.
So, the BSN is considered to have a wider exposure to knowledge (whether or not she uses all that info is another thread

)
This is a general description, no 2 programs at any level are exactly alike: and I am sure many ADN programs go beyond the basics I described. But the NLN and the AACN are the bodies setting the numbers of hours needed, and for accreditation the schools follow the guidelines pretty closely. Its really tough to try to fit everything in that faculty "think" should be there, my professor called it "credit creep".
