Singh was educated at Doon School, Dehra Dun, a boarding school, which represented a departure from the usual practise of princes being educated by tutors at home. The school was very elite, but it nevertheless meant that Karan Singh shared the classroom (though not the hostel) with boys from non-royal backgrounds, and received a standard education. Unusually for the scion of an Indian royal family, he then enrolled in a college for a graduate degree, receiving first a B.A. degree from Jammu and Kashmir University, Srinagar, and subsequently an M.A. degree in Political Science and a PhD degree from University of Delhi.
