The National Accreditation Council (CNA) is a sectorial advisory and coordination body created to coordinate, plan, recommend and advise on the accreditation of higher education institutions and academic programs in Colombia. Program accreditation is a voluntary process and temporary in nature with periods ranging from three to ten years. The process includes external evaluations by peers and site visits. There are separate processes for undergraduate and graduate program accreditation. The CNA has recently developed various internationalization activities in order to participate on a broader international scope of accreditation and to promote ties of cooperation and integration with relevant agencies around the world.
