Post-graduate level higher education covers study undertaken after a first degree or equivalent qualification. Universities and other higher education providers offer courses such as master's degrees, postgraduate certificates and diplomas, research degrees including doctorates, and professional or specialist qualifications. Subjects range from arts and humanities to science, technology, business, education and healthcare. Courses may involve taught classes, independent research, practical training or a combination of these. Study can be full-time or part-time, and some providers offer distance or blended learning. Entry requirements vary by course and may include a relevant undergraduate degree, professional experience, a portfolio or evidence of research ability. Providers typically give information about applications, course content, assessment, supervision, academic support and the qualifications awarded.
