Online higher education has attained scale and is poised to take the next step in its growth. Although significant obstacles to a full scale adoption of online education remain, we will see full scale adoption of online higher education within the next five to ten years. Practically all higher education students will experience online education in some form during their collegiate career, and college students will be able to take online or blended degree programs and certificates in almost any subject. Full scale online education will occur as the result of compounded growth, increased familiarity and acceptance, various models of scalability, and possible wildcards which may accelerate growth. Online education will also attain full scale by becoming fully integrated into mainstream education. This transformation is necessary for online learning to reach its potential to improve the quality of education.
