Students were asked to rank instructors, who differed by age, gender and political leaning, by their expected helpfulness, and how much a student expected to learn. Students selected older instructors as those from whom they would learn the most, but chose young instructors as the most helpful. Overall, male instructors were preferred over female instructors, especially when emphasis was placed on learning. The political leaning of the instructor was a discriminating factor in humanities classes, with liberal instructors preferred over conservatives. The preferred age, gender and political leaning patterns were distinctly different for instructors who were helpful, and from those from whom students thought they would learn the most, indicating a dichotomy between perceived helpfulness and learning. The stereotypic images of instructors did not differ significantly by the students' own gender and academic major, except for male students ranking conservative instructors higher than females. Students do have stereotypical images of instructors based on the instructor's age, gender and political leaning.
