What is a Caste Certificate and Why is it Needed?

A Caste Certificate is the proof of one's belonging to a particular caste, especially in case one belongs to any of the 'Scheduled Castes', as specified in the Indian Constitution. The Government felt that the Scheduled Castes and Tribes need special encouragement and opportunities to progress at the same pace as the rest of the citizenry. As a result, as part of the Indian system of Protective Discrimination, there exist certain special privileges granted to this category of citizens, such as reservation of seats in the Legislatures and in the Government Service, waiving off a part or the whole of the fees for admission to schools and colleges, quotas in educational institutions, relaxation of upper age limits for applying to certain jobs, etc. To be able to avail these privileges, a citizen belonging to a Scheduled Caste must be in possession of a valid Caste Certificate.
