The National Commission for Scheduled Tribes (NCST) is an independent body set up to monitor and investigate the implementation of the rights and privileges accorded to the scheduled tribes in India. It also participates and advices in the planning process regarding tribal policy matters.

Of particular interest to me, for my research project was the document published by the NCST, elaborating its views on tribal education and steps to improve it, as forwarded to the Planning Commission for the five year plan for 2012-17
A detailed document explaining the structure of tribal welfare in India can be a good read to understand the scenario in India
