Any candidate who has qualified the entrance examination is eligible for Central pool quota. The existing reservations are for Scheduled Caste (15%), Scheduled Tribe (7%), OBC-NCL (27%) and PWD (3%). Except for these there are no other reservations. If a wife of paramilitary soldier falls under any of these criteria then she is eligible for that specific criteria. However State quota might have reservation for serving/ex servicemen and it depends on the rules of that particular state.
