Higher education is an educational level that follows the completion of a school providing a secondary education, such as a high school, secondary school, or gymnasium. Tertiary education is normally taken to include undergraduate and postgraduate education, as well as vocational education and training. Colleges, universities, and institutes of technology are the main institutions that provide tertiary education (sometimes known collectively as tertiary institutions). Examples of institutions that provide post-secondary education are vocational schools, community colleges, independent colleges (e.g. institutes of technology), and universities in the United States, the institutes of technical and further education in Australia, CEGEPs in Quebec, and the IEKs in Greece. They are sometimes known collectively as tertiary institutions. Completion of tertiary education generally results in the awarding of certificates, diplomas, or academic degrees.
