Yes, there is a reservation policy for candidates in the UPSC civil services examination, aimed at enhancing social equity. Categories such as Scheduled Castes (SC), Scheduled Tribes (ST), and Other Backward Classes (OBC) receive certain percentage benefits in terms of seats reserved. Additionally, a quota is available for economically weaker sections (EWS) to ensure inclusivity. These reservations not only provide opportunities for marginalized groups but also help in fostering diversity within civil services, ultimately contributing to a more representative governmental framework.
