This quantitative study is designed to determine the impact of online proctoring software in graduate courses. The researchers compared the final grades of two groups of online graduate students who were taught by professors who had online exams before and after the university implemented proctoring software. Essentially the only difference between the groups was the use and nonuse of proctoring software. The overall sample in this study were 426 students in six different online graduate nursing courses at a medium-sized, public university in the United States. The findings showed the implementation of online proctoring software had a statistically significant impact on the students' course grade when all the graduate courses were regressed together. The authors also regressed the data using independent human capital variables (i.e. male/female, full/part-time status, and cumulative GPA). Student cumulative GPA also proved statistically significant for the group of graduate nursing courses.
