Understanding how many colleges and universities in North America use remote proctoring technologies matters to students, faculty, staff, and administrators, and it is important for practical, scholarly, and ethical reasons. Beyond rough estimates and statements on proctoring software sites, there’s little data on the prevalent of proctoring software. Royce Kimmons and I tried to estimate proctoring software penetration by programmatically searching 2,155 college and university websites in the U.S. (n = 1,923) and Canada (n = 232) to determine how widely these tools and services were being used. We found that nearly 63% of colleges and universities in the U.S. and Canada use proctoring software, with U.S. institutions being much more likely to use them than Canadian institutions. We report our detailed results in EDUCAUSE review.
