Under the supervision of the faculty, Graduate students often serve as instructors for beginning and intermediate language courses and as section leaders for large Classical Civilization courses. This is a general practice in American universities with graduate programs, and teaching is regarded as part of the essential duties of graduate students. They do not teach advanced courses in Greek and Latin or direct Classical Civilization courses except in extraordinary cases. Graduate student instructors are extremely knowledgeable and energetic, and they share the faculty’s goal of excellence in teaching.
