"Qualified teachers" apparently isn't a necessity when the school's only goal is to flush the proverbial toilet (out with the old, in with the new).

After I finished my MA and was hunting around for PT teaching, I submitted a few course outlines/designs to local universities/colleges only to be ignored.  Well, not completely - I did have one enquiry asking me to go into further detail.  A year later, the school now offers a course that isn't just similar to the one I planned - it IS the course!  

And I'm not teaching it.

It seems that "Always accepting applications for adjunct positions" is just an academic bait & switch to get others to do their research for them.  

Maybe it's the department heads who are "unqualified".
