The department also cares about its accreditation. The professors want grad students who can handle advanced chemistry. <i>Someone</i> has to teach them.<p>&gt; The grad class doesn&#x27;t make the university any money.<p>Odd, I could have sworn that my grad school listed a cost for credit hours. While there was a tuition waiver, that money came from somewhere, and I&#x27;m pretty sure that includes grant overhead.<p>I&#x27;m sure too the funding agencies might wonder about all the overhead needed for a grad school with no one teaching graduate-level courses.
