The purpose of the study presented in this chapter was to examine students’ perceptions of the importance of various indicators of teaching presence for their success in online courses. A cross-sectional survey design was used to identify the indicators that students perceived to be most important and to determine whether there were potential differences between graduate students and undergraduate students in terms of the students’ perceptions. Although the indicators that students rated as most important were similar for both groups of students, there were statistically significant differences for a few of the indicators. Students’ comments suggested additional indicators and provided insights about the importance of dispositions in online courses.
