The nineteenth century saw a great expansion in the variety of master's degrees offered. At the start of the century, the only master's degree was the MA, and this was normally awarded without any further study or examination. The Master in Surgery degree was introduced by the University of Glasgow in 1815.[8] By 1861 this had been adopted throughout Scotland as well as by Cambridge and Durham in England and the University of Dublin in Ireland.[9] When the Philadelphia College of Surgeons was established in 1870, it too conferred the Master of Surgery, "the same as that in Europe".[10]
For example, astronomy degrees take five to six years on average, but observational astronomy degrees take six to seven due to limiting factors of weather, while theoretical astronomy degrees take five. Though there is substantial variation among universities, departments, and individuals, humanities and social science doctorates on average take somewhat longer to complete than natural science doctorates. These differences are due to the differing nature of research between the humanities and some social sciences and the natural sciences, and to the differing expectations of the discipline in coursework, languages and length of thesis. However, time required to complete a doctorate also varies according to the candidate's abilities and choice of research. Some students may also choose to remain in a program if they fail to win an academic position, particularly in disciplines with a tight job market; by remaining a student, they can retain access to libraries and university facilities, while also retaining an academic affiliation, which can be essential for conferences and job-searches.

The Professional Science Master’s degree in Fisheries and Wildlife Administration (PSMFWA) provides advanced training for recently finished undergraduates looking to enter the workforce or early-career professionals employed by natural resources agencies, non-government organizations, and other entities seeking to advance their careers. The PSMFWA also provides an opportunity for employers to...

Currently, the department is concentrated primarily on earthquake engineering, a field in which Caltech researchers have been important contributors since the 1920's. Research is currently being conducted in areas such as seismic early warning, characterization of near-source motion in earthquakes, soil-structure interaction, nonlinear finite element analysis of civil structures, structural health monitoring and earthquake loss-estimation.
Some graduate programs also have a more significant research component than undergraduate studies. And other graduate schools offer professional degrees which may be more focused on practical skills and knowledge. Examples include the MBA, MPA, PsyD and DNP. The type of grad school you attend, degree you seek and chosen area of study will play a large role in determining your graduate school experience.
It might be awkward, but please don't scroll past this. This Sunday we humbly ask you to defend Wikipedia's independence. Our 2019 fundraiser is running out of time. 98% of our readers don't give; they simply look the other way. If you are an exceptional reader who has already donated, we sincerely thank you. If you donate just $2.75, Wikipedia could keep thriving for years. Most people donate for a simple reason—because Wikipedia is useful. If Wikipedia gave you $2.75 worth of knowledge this year, take a minute to donate. Show the volunteers who bring you reliable, neutral information that their work matters. Thank you.
