UCLA started a BA in public policy a couple of years ago. It is a lot more practically oriented than their PoliSci major which is more widely known (and very popular at most colleges), because PubAff includes a wider range of courses and a full year capstone internship during senior year. PoliSci is often quite a short major so may be combined with other majors or minors eg PoliSci/Econ is a common combination.
