What is a "full-time teaching faculty" (and does advising count)?
You'd have to ask him to know for sure, but I would expect "full-time teaching faculty" to refer to full-time faculty whose duties include a substantial amount of teaching.  It would exclude adjunct professors and other part-time faculty, and would also exclude faculty who never or rarely teach.  I expect that very few college or university faculty positions literally involve teaching "full-time".
