I am completing my BSN-PhD degree in effort to teach at a university level as well. Keep in mind that many universities offer academic tracks other than just tenured and clinical tracks. You may also receive a research or a fixed-term faculty appointment as well where your time is divided between classroom teaching and research/policy, ect. My advice to you is to seek out a PhD (research degree) or a DNSc. You may be more utilized and employable in nursing, health care policy/legislation, research, consulting, pharmaceuticals, ect. An EdD is more of a degree of the past as far as nursing is concerned and is not favored among nursing schools. Many doctorate degrees are incorporating education cognates/electives into their curriculums to prepare nursing faculty as well. Good luck to you!
