My accelerated / 2nd degree BSN program at Research College of Nursing in Kansas City is a 12 month program that runs from August to August. Before the start of the program, we are required to take 15 credits at Rockhurst University, which RCoN is affiliated with. I took all the 15 credits in the summer before the start of the program, so it ends up being a 14 month program.
It takes longer if you still need to finish your prereq's, but to be honest, the prereq's for nursing school are easy (as are most of the nursing school classes). The only difficulty in my program is the volume, not the depth of information.
Sigh...I wish there was a PA program in KC.
