As I checkout job posting for teaching jobs, I see many ask for a doctorate with a specialization or concentration in a particular discipline. I have a Master Degree in Entrepreneurship (Not an MBA but 30 credit hours of Entrepreneurship). Would this combined with a general DBA meet the above qualifications, if the dissertation was focused on Entrepreneurship?
If the position was for teaching Entrepreneurship, than I would think your masters degree and a DBA with a dissertation focused on Entrepreneurship would meet their requirement. However, it is really up to the people doing the hiring.
Entrepreneurship is normally not a recognized specialization within a DBA, a general DBA should do it as I strongly doubt that there are many specialized programs at the doctoral level in this area. Most specialized DBAs are in Finance, Accounting, Management, Marketing and OM.
Another question is how much competition you'd have. That's pretty specialized. Depending on which schools you've attended and will attend, and which school is hiring, I'd think you'd be attractive to hiring committees with that combination.
Walden University Accredited Online University Degree Programs | Online College | Online School | Walden University and California Intercontinental University Caluniversity | Online University Degree Programs | CalUniversity Accredited Programs both offer the DBA in Entrepreneurship.
Keep in mind those job ads may be crafted with a view to rolling over an existing incumbent into a new contract. They may need to post the ad to satisfy HR fairness policies, but there often is someone in the job who is doing well and it's more of a formality. Whenever you see an ad looking for very specific and rare credentials, then that can be a sign that there is an incumbent. If you know people in the school, ask them. It's theoretically possibly that someone remarkable can come in from the outside and knock out an incumbent, but it rarely happens in my experience.
You don't have to get one, but it's wise to align at least 18 credits into a specialization that you're interested in. Don't get a doctoral specialization in entrepreneurship since you already have a graduate specialization in it. Broaden your horizons (and marketability) by getting a different specialization, even if it's just in management or some other soft business subject.
Agreed, although if you can do it, finance or accounting would be useful both for entrepreneurs and just because there's more demand for instructors in those areas.
