<p>What weather test is that? Every single (tenure-track) faculty member that is hired has to stand up in front of the department (and often graduate students) and give an hour-long presentation on his or her research. The whole point is to assess the candidate’s oral communication skills. every single one has satisfactorily passed that hurdle on the way to being hired, implying that other department members and students have found it quite possible to understand him or her. What more would you have them do? TOEFL for faculty jobs? Stop hiring anyone whose native language isn’t English? It’s not something you can just wave your hands at and it will go away.</p>
<p>About the best you could hope for is job offers conditional on taking classes aimed at helping improve their grasp on the english language if that is the primary language of instruction.</p>
