I think going back to school is a matter of personal goal. I am an APRN, MSN, FNP-C, PMHNP-BC. In the far future when DNP will be the entry level for Advance Practice Nursing, I'll be grandfathered in. However, I still have 20 years before retirement. So if I want to compete with the newly grads with their Doctorate, I feel that I can use that. DNP/PhD programs in Univ of AZ is a 5 year on-line program. DNP they say is more "clinical", in my current job it won't make a difference. PhD will open doors in teaching at State Universities. Still torn on doing the dual program or go straight to PhD.
