A terminal degree is the highest-level college degree that can be achieved and awarded in an academic discipline or professional field. In other cases, it is a degree that is awarded because a doctoral-level degree is not available nor appropriate. An earned academic (or research) doctorate such as a Ph.D., Ed.D. or D.B.A. is considered the terminal degree in most academic fields, as well as the most advanced degree possible, advancing the boundaries of human knowledge through research and dissertation defense, in the United States. However, professional doctorates may be considered terminal degrees within the professional degree track, even though they are prerequisites for research degrees, for example, Doctor of Medicine (MD) or Juris Doctor (JD) in the United States. The phrase "terminal degree" is used heavily in the United States, but is used less in other countries. The term is not generally used in the United Kingdom or Canada, for example, and its exact meaning varies somewhat between those areas and disciplines in which the term is used. In some countries there are degrees which are more advanced than the PhD, such as the higher doctorates in the United Kingdom and Russia, and the habilitation degree awarded in Germany and Austria. Not all terminal degrees are doctorates. For example, in professional practice fields there are often terminal master-level degrees, some which are called doctorates e.g. MEng (Master of Engineering), MLArch standing for Master Landscape Architect or BEng for Engineers, MB (Bachelor of Medicine (UK)). Architecture was a discipline where the M.Arch was considered terminal as a professionally oriented degree, but a Doctor of Architecture (D.Arch) that is recognized by the National Architectural Accrediting Board (NAAB) establishes the doctoral level as the highest level of "professional degree" in architecture in the United States. For the same discipline of Architecture, the "Laurea di Dottore" is the terminal degree in Italy. Interior design and Interior Architecture have terminal master-level degrees such as MID, MA, MS interior design education. Most non-doctoral degrees are not terminal in academic terms, with the exception of the Master of Fine Arts (MFA), an academically recognized terminal degree given to practitioners in the fine arts and performing arts. The Master of Business Administration (MBA) is also considered a terminal professional degree. Research degrees In academic fields, the typical terminal degree is that of Doctor of Philosophy, although others also exist. The first phase of the Ph.D. consists of
