These three little letters stand for a big degree: a Doctorate in Nursing Practice. It is the terminal degree in nursing education, so it is the highest level of schooling in the field. In other words, this degree is for all you overachievers out there.
In all seriousness, though, the DNP degree pushes your career one step further in the best way possible. You become an expert, a leader and someone who influences patient care and policy.
