The Nuffic Glossary is a list with explanations of terms used in Dutch education.
One of the many types of university master's degree programmes. Two-year programme focussed on scientific research. Often there are extra admission requirements. The term itself does not convey this specifically Dutch meaning, however. In fact, some readers would be misled into a comparison to the MRes degree, which in Britain is a step midway between a first degree and a PhD. It would be safer simply to explain that this is a master's degree programme with a strong research component. (See the entry for mastersopleiding).
