Development Commissioner for Hill Areas of Assam (DCHA) is the Plan preparation, co-ordination, monitoring and evaluation agency for the Plan Schemes of the two hill districts. This office compiles the physical and financial progress of the Entrusted and Non-entrusted schemes of all sectors and furnishes the same to the Planning Commission. DCHA allocates fund among the development sectors of the two Autonomous Councils. DCHA leads a team of Principal Secretaries of the two Hill Autonomous Councils and major nodal Officers in the Hill Areas Development Programme (HADP) discussion in the Planning Commission. These hill areas are administered as per the provisions of the Sixth Schedule of the Constitution of India. A Joint Centre-State Study Team was constituted in 1965 by the Planning Commission to study the development programmes of the Hill Areas of Assam. The team was headed by Shri Tarlok Singh, the then Member, Planning Commission, which later became known as Tarlok Singh Committee. The Committee suggested to “ (1) Constitute a Planning Board for the Assam Hill Region which should be presided over by the Chief Minister and (2) to appoint a Development Commissioner for the Assam Hill Region who would also function as Secretary to Planning Board for the region”. Office of the Development Commissioner for Hill Areas was created in 1966 to coordinate the developmental works in the Hill Areas of Assam more or less in the same line as the Planning and Development Department for the plains areas of the state.
