Laura, at University of Wisconsin-River Falls (a primarily undergraduate institution of fewer than 6,000 students, standard teaching load 12 hours per semester), we have no blanket policy--it's up to the dept chair, dean and/or provost.  A dean recently refused to allow a faculty member to buy out all of her teaching time through grants (she had several).  That's an unusual circumstance for us; typically, grant recipients will buy out one course, occasionally two.

Replacements are almost always adjuncts, what we call in Wisconsin academic staff (teaching), who have no responsibilities outside the classroom.  But once again, there is no blanket policy.

Regards, Bill
