During the British Raj, some methods for upliftment of these lower castes were introduced by the British, progressive thinkers and Hindu reformers. These included reservations in the legislature and in government jobs. After independence, the Indian constitution introduced provisions for reservations for the Scheduled Castes and Tribes (SC/ST) in government institutions, to give a fair representation to the weakest sections of society i.e. Dalits and Adivasis. 22.5% of the seats (SC- 15%, ST- 7.5%) in higher education institutes and public sector undertakings at both state and central level were set-aside for them. Uplifting the SC/ST's representation par with the upper castes has not yet been achieved.
