A thesis or dissertation[1] is a document submitted in support of candidature for an academic degree or professional qualification presenting the author's research and findings.[2] In some contexts, the word "thesis" or a cognate is used for part of a bachelor's or master's course, while "dissertation" is normally applied to a doctorate, while in other contexts, the reverse is true.[3] Dissertations and theses may be considered as grey literature.
The required complexity and/or quality of research of a thesis or dissertation can vary by country, university and/or program, therefore, the required minimum study period may vary significantly in duration.
The word dissertation can at times be used to describe a treatise without relation to obtaining an academic degree. The term thesis is also used to refer to the general claim of an essay or similar work.
