I wold thing that if the switch was made in 2015, it would have to be done so that NEW students just starting would have to be in a DNP program. Hopefully nurses aren't so short sighted as to say to people who are already students in master's program before 2015, here is your degree, its worthless, go back to school.
If it comes to pass that DNP is required, it will be after 2015 when all schools
are DNP programs already. No nursing board is going to create a requirement that can't be met.
I don't think conversion to a DNP compares to bachelor's for entry practice at all. That has been a controversy for years. But that is just for entry level nursing, not advanced practice. And the nation is dependant on associate degree programs providing nurses for basic practice. MSN to DNP would not require closing many programs, and hopefully won't decrease the advanced practice working pool--I have my doubts though. How many part time students who are full time caregivers will be able to burden a year or more of school? Will the increased tuition deter them?
Most associate programs would have to close completely, until a major nurse surplus occurs this just isn't going to happen. With the aging population there will be nursing shortages for years to come. The advanced practice nurses are in a much more secure footing to make the switch, ADN to BSN nurses are not.
