MBA professors must meet the school's minimum number of hours in a subject. A professor who wants to teach accounting, for example, may be required to have passed 12 hours of graduate-level courses in accounting. Some large schools prefer professors with a Ph.D. in the subject matter they wish to teach. This is less common with small schools and community colleges.
Since class times change from semester to semester, professors need to be ready to teach at different times and in different buildings. Professors can't always determine their schedule, but they can state their preferences when they are hired. Professors who are just starting out may need to work for multiple schools at the same time in order to make ends meet.
The majority of colleges require applicants to have been teaching assistants (TAs) or to have passed seminars about teaching methods. TAs are students who get paid to assist professors. The teaching seminars provide instruction on topics like creating a syllabus and grading papers.
Applicants at some schools are expected to have had research or a book published. These schools tend to be ones that are known for research. Professors with published work add prestige to a college's reputation. This requirement is also an indicator that the school expects its professors to publish regularly.
Schools want applicants with academic references who can vouch for their experience and work habits. Your best references will come from a dean from your old school or from previous teachers. Give your references plenty of time to write a reference, and give them instructions on how to submit the reference.
