Current research indicates that online student grades have dropped at for-profit online institutions, where adjunct online faculty made up for 80-90% of online faculty. Evidence of low online student grades in an era of increased use of adjunct online faculty exists. A quantitative nonexperimental study examined the relationship between adjunct online faculty working at a private for-profit online institution and online student grades. A total of 81 out of 148 faculty members participated. Results indicated technological, pedagogical, and content knowledge of adjunct online instructors did not predict online student grades; however, other variables are discussed in this article that may contribute to low online student grades.
