How much public policy is it? What kind of internships do people get? I really want to study politics, but I would prefer to get the more practical education in public policy rather than the theoretical political science version.
Also if anyone could comment on the city and regional planning minor that would be awesome!
I’m not currently a GW student, but I just applied ED for the Poli Sci w/Public Policy focus major for what sounds like very similar reasons to you. When I stayed overnight for a GW program I got the chance to sit in on a Poli Sci class and talked to the professor about the Public Policy concentration. I asked her if it geared away from the theoretical and more into the applicational. She said that it very much did, and that it truly put their motto of “Knowledge in action.” to work. Public Policy focused students take more applicational classes for that concentration than you would otherwise not get with a straight poli sci major. I don’t know if the internships differ between the poli sci major and the public policy focused major, but I do know that many students of both majors apply and often get internships at the White House, the Capitol, the Peace Corp, and other non-profit and for-profit organizations in the city. I’m afraid I’m not very specific, but I hope that’s all helpful. As for the city and regional planning minor, I’m afraid I don’t know much about it, sorry. Maybe someone else who knows more about it could comment? Anyways, good luck with college apps! 
Hey, I’m a current sophomore at GW majoring in Poli Sci with a Policy concentration. First of all I just want to point out that a student doesn’t necessarily get more internship opportunities based solely on their major/concentration. For instance, I interned for a historical commission last spring though I’m neither a history major or minor. Where you intern is more about searching online (G Work is a very good source–that’s where I found my current internship) and just networking well.
Also the concentration is really not much different from the general major. You have to take three courses in Poli Sci relating to policy (a few people I know have basically done that w/o declaring this as a concentration), plus two econ classes and two statistics classes. Of course, upper level economics and statistics are not for everyone, so again this concentration isn’t required to go into a career in policy. Really it’s simply a nice qualification to get if you intend on taking policy and economics classes (as I am).
Also I’ve never heard of GW offering a city planning minor, though that sounds great. Good luck!
