You are incorrect. Professor is a position at a college or university, NOT dependent on a doctorate (the appropriate title for a person with a doctorate is "Doctor" unless he/she also is a professor). Many many professors at universities and colleges have only a Master's degree, and there are some appointed professors out there with only a Bachelor's degree (or even no degree), their being hired/appointed based on their career experience.
I have a Master's in Parapsychology from JFK University, AND am an Adjunct Professor at JFK University AND a faculty member at Atlantic University (with the title "Professor").
I know numerous Associate Professors and Assistant Professors who worked YEARS and YEARS just to attain the deserved title of Professor - ALL Ph.D's. I have taught at the university level, and do not hold a Ph.D and would NEVER consider myself a professor. I know of no professors who do not hold a doctorate. I am glad you have found a place that gives out the title of Adjunct Professor to non-doctoral instructors and stand corrected in your case.
Wiki:
A
professor is a scholarly
teacher; the precise meaning of the term varies by country. Literally,
professor derives from
Latin as a "person who professes" being usually an
expert in arts or sciences, a teacher of high rank.
[1] In much of the world, including most
Commonwealth nations (such as the
United Kingdom,
Australia,
New Zealand,
South Africa, English-speaking Caribbean) and northern Europe
professor is reserved only for the most senior
academics at a university, typically a department chair, or an awarded chair specifically bestowed recognizing an individuaI at a university or similar institution.
A professor is a highly accomplished and recognized academic, and the title is
in most cases awarded only after decades of scholarly work to senior academics.
In the United States and Canada the title of professor is granted to most scholars with doctorate degrees or equivalent qualifications (typically Ph.D.s) who teach in two- and four-year colleges and universities, and is used in the titles
assistant professor and associate professor,
which are not considered professor-level positions [2] in many other countries, as well as for full professors.
Beyond holding the proper academic title, universities in many countries also append famous artists, athletes and foreign dignitaries with the title
honorary professor, even if these persons don't have the academic qualifications typically necessary for professorship. However, such "professors" usually do not undertake academic work for the granting institution.
