Most world universities use a multiple chapter format : Degree-awarding institutions often define their own house style that candidates have to follow when preparing a thesis document.
In addition to institution-specific house styles, there exist a number of field-specific, national, and international standards and recommendations for the presentation of theses, for instance ISO 7144.
"Dissertation" comes from the Latin dissertātiō, meaning "discussion".
Aristotle was the first philosopher to define the term thesis.
According to a committee resolution, the dissertation can be approved or rejected by an academic committee consisting of the thesis director, the thesis coordinator, and at least one evaluator from another recognized university in which the student is pursuing his or her academic program.
All the dissertation referees must already have achieved at least the academic degree that the candidate is trying to reach.
In the US, these committees usually consist of a primary supervisor or advisor and two or more committee members, who supervise the progress of the dissertation and may also act as the examining committee, or jury, at the oral examination of the thesis (see below).
At most universities, the committee is chosen by the student in conjunction with his or her primary adviser, usually after completion of the comprehensive examinations or prospectus meeting, and may consist of members of the comps committee.
Presentation requirements, including pagination, layout, type and color of paper, use of acid-free paper (where a copy of the dissertation will become a permanent part of the library collection), paper size, order of components, and citation style, will be checked page by page by the accepting officer before the thesis is accepted and a receipt is issued. Most Italian universities, for example, have only general requirements on the character size and the page formatting, and leave much freedom for the actual typographic details.
A thesis or dissertation committee is a committee that supervises a student's dissertation.
