Tertiary education, also referred to as third stage, third level, and post-secondary education, is the educational level following the completion of a school providing a secondary education. The World Bank, for example, defines tertiary education as including universities as well as institutions that teach specific capacities of higher learning such as colleges, technical training institutes, community colleges, nursing schools, research laboratories, centers of excellence, and distance learning centers. Higher education is taken to include undergraduate and postgraduate education, while vocational education and training beyond secondary education is known as further education in the United Kingdom, or continuing education in the United States.
