Higher education includes teaching, research, exacting applied work (e.g. in medical schools and dental schools), and social services activities of universities. Within the realm of teaching, it includes both the undergraduate level (sometimes referred to as tertiary education), and beyond that, graduate-level (or postgraduate level) for qualified students who wish to go further in their education and skills. This level of education is often referred to as graduate school, especially in North America.
In the United Kingdom and certain other countries (e.g. Ireland), post-secondary school education below the level of higher education is referred to as "further education". "Higher Education" in the U.K. generally involves work towards a college-degree-level or foundation degree education.
