The National Center for Education Statistics (NCES) conducted a distance education study based on the 2001-2002 academic year at United States 2-year and 4-year degree-granting institutions that were eligible for U.S. federal student aid. The study reported that 56 percent of institutions surveyed offered distance education courses. The study also found that public institutions were more likely to offer distance education than private institutions were.[13]
The Sloan Consortium, based on data collected from over 2,200 U.S. colleges and universities, reports that nearly 3.2 million students took at least one online course during 2005 (a significant increase over the 2.3 million reported in 2004). According to the same report, about two-thirds of the largest institutions have fully online programs.[11] In 2010, more than 6 million students were taking at least one course online
