Criteria for selecting UPSC examination centers include geographical accessibility, amenities, and sufficient infrastructure to handle the candidate volume. Proximity to urban areas often ensures better facilities and public transport options. Availability of necessary resources such as libraries or coaching centers also plays a role in decision-making for aspirants. Additionally, past experiences of candidates, including exam security and center management, influence future center selections. The UPSC aims to provide centers that create a conducive environment for candidates, balancing accessibility with the necessary facilities to support candidates in fulfilling their aspirations.
