ABSTRACT This paper explores the effects of part-time instructors in the Principles of Marketing course at a comprehensive IIA university in the Mid-South. We find part-time instructors assign grades 0.86 points higher than assigned by full-time instructors. Using a multiple linear regression, in which the response variable is students' grades, the explanatory variable instructor status--i.e., full-time or part-time--is statistically significant at less than a 0.01 level of confidence (p-value = 3.4E-22). Additionally, the explanatory variable grade point average (GPA) is also significant at an alpha level less than 0.01 with a p-value of 1.57E-51. The model yielded an adjusted R2 value of 0.52, indicating that 52 percent of students' grades are accounted for by the explanatory variables included in the model.
