A double-degree program, sometimes called a combined degree, conjoint degree', dual degree, or simultaneous degree program, involves a student's working for two different university degrees in parallel, either at the same institution or at different institutions (sometimes in different countries), completing them in less time than it would take to earn them separately. The two degrees might be in the same subject area (especially when the course is split between countries), or in two different subjects. Undergraduate double-degree programs are more common in some countries than others, and are generally found in countries whose higher-education systems follow the British model.^{[citation needed]}Master's double-degree programs are more widespread. Interest in double-degree programs between member nations has spread in the European Union, as the gaining of qualifications from more than one country is seen as an advantage in the European labour market.

Typically in a double-degree program both of the participating institutions reduce the amount of time required to be spent at each. Common Undergraduate double degrees include Engineering and Economics program, Engineering and Business program such as Business and Computing. They often take 4–5 years to complete instead of 7–8 years to complete separate degrees. Common postgraduate double degrees are J.D./M.B.A. degrees, as well as M.B.A. and J.D. degrees combined with M.A. fields such as politics, economics, urban planning, and international relations. Many medical schools also offer joint M.D. degrees with J.D. and M.B.A. programs, as well as with a range of M.A. programs. Some universities even offer dual Ph.D./M.B.A degree, Ph.D. portion is mainly in science and engineering, which target entrepreneurs and venture capitalists.
