About teachers, the Education Commission (1964-66) had observed, of all the factors that influence the quality of education the quality, competence and character of teachers are undoubtedly the most significant. In a view to strengthen the teacher education, the National Policy on Education (NPE 1986) and Programme of action (POA 1992) envisaged a District level Institute in the shape of District Institute of Education and Training (DIET).
Prior to the adoption of NPE, National level and State level Institutions like NCERT, NUPEA and SCERT provided support to the elementary Teacher Education particularly in the area of pre service teacher educaion. As per the guidelines of NPE, a Centrally sponsored Scheme of Restructuring and Reorganization of Teacher Education was approved in October 1987, thereby a third-distric-level-tier i.e. District Institute of Education and Training Institutes were formed throughout the country in all districts.
