There are several important questions you need to ask yourself relative to your intended audience, setting, and subject matter. There are definite needs for nurse educators, but you will want to be sure you pursue the right program for your long term goal.
do you want to teach? Do you want to be a patient educator, work in the education department of a hospital (teaching other nurses), or work for a school of nursing and teach either RNs or prelicensure students? If you want to be a patient educator or a staff educator, a MSN in Education is an excellent option for you. If you want to teach students, then proceed to the next question.
2. Assuming you want to teach students, then the next question to ask is what kind of students (pre-licensure or post-licensure) and in what setting (community college, BSN program, MSN program, etc). Added to this, what type of school do you want to be on faculty -- a college that focuses on preparing RNs, or a university which is also engaged in research/practice innovation?
3. The last question to ask yourself is what
do you want to teach? If you want to teach something that is specialty based (critical care, pediatrics, community health, informatics) then you really should consider a graduate degree in that specialty area and perhaps minor in nursing education. If you want to teach more general items (health assessment, nursing skills, theraputic communication) to nursing students, then an advanced degree may not be needed. Also, do you want to teach clinicals only or teach didactic?
My University is a top-15 SON, and we teach nursing at many levels (high school entry all the way through DNP and PhD). We have approximately 100 faculty (tenure-track as well as regular track faculty on yearly contracts). We have only one faculty member (of 100) with a MSN in Education - she coordinates the testing and evaluation programs for the prelicensure students (HESI, Evolve, etc). The faculty with doctorates (DNP and PhD) do the classroom instruction at all levels; those with MSNs in specialty areas and DNPs are the clinical instructors. But keep in mind that there are over 1,000 accredited and non-accredited nursing programs
in the US - and different schools have different criteria for faculty. Individual hospitals also have different criteria to become a staff educator.
There is no requirement that you have to have a graduate degree by a set calendar year or a specific birthday. So before selecting a graduate program, I would recommend that you consider what you want to do 10 and 20 years from now and then select the right program to get you there. You do not want to do a doctoral program in something and then have an "oops" moment.
