I’ve done an MPP [or MBA]. Are the core courses I had in economics and statistics likely to fulfill PRGS requirements?
It depends, and you’ll have to talk it over with your professors here. Sometimes the answer turns out to be no. The right way to think about this may be that the usual master’s program tries to create people who are good consumers of research, while PRGS enables people to be excellent producers of research. It’s not that the prior work isn’t useful, rather that it may be a good conceptual foundation on which to build advanced research skills.
