This article is a reflection derived from a broader regional comparative research that studies the changes within the processes of regionalization. Also, it shows the greater tendency toward forms of decentralization (new institutions and different mechanisms) over traditional forms of decentralization (offices, sub-offices or subsidiaries) that characterized the regionalization of higher education in the continent. This research reveals various mechanisms of regional higher education services, mainly public but also private, which are also those who have supported over the years the expansion of enrollment and have increased coverage.
