The criteria considered for reserved categories in the UPSC include age relaxation, number of attempts, and specific qualifying marks. These provisions aim to promote inclusion and equal opportunities for individuals from Scheduled Castes, Scheduled Tribes, and Other Backward Classes. Age limits are typically extended by a few years for these categories, acknowledging systemic disadvantages faced by underrepresented groups. Moreover, the number of attempts allowed may be higher compared to the general category, ensuring that candidates from reserved categories have fair access to government services through affirmative action.
