What makes online colleges popular? By popularity, we simply mean the number of students attending a school. The greater this number, the more popular the online college.
Although popularity doesn't directly gauge quality of education (see our ranking of the best online colleges for that), it is a good indicator of quality because students do not flock to a school unless it offers something valuable.
The most popular online schools on this list all have strong brands---they're established leaders in the online education field. The list includes schools specializing in online education as well as more traditional campus-based schools with a significant online presence.
We gathered the numbers, representing part-time and full-time students, from the U.S. Department of Education's Integrated Postsecondary Education Data System (IPEDS), the colleges' own websites, and news reports. We also contacted school representatives and received data directly from them.
We selected the most popular online schools based on online student enrollment. We rounded the numbers to the nearest 1,000.
