In this paper special consideration certain ethnic minority groups, traditionally re- ferred to as tribes or tribals, as Scheduled Tribes (STs) who constitute around 8 per cent of the total population of the country. There are 573 STs living in different parts of the country. Since primacy was accorded to elementary education, a broad policy frame for education was adopted in the tribal sub-Plans according equal importance to quantitative and qualitative aspects of education. A second important development in the policy towards education of tribals came with recommendations of the National Policy on Education (NPE) in 1986. The reasons for this can be categorized as external, internal, and socio-economic and psychological. The external constraints are related to problems and difficulties at levels of policy, planning, implementation, and administration. Internal constraints refer to problems associated with the school system, content, curriculum, medium of instruction, pedagogy, academic supervision, monitoring, and teacher-related problems. The third set of problems relates to social, economic, and cultural background of tribals and psychological problems of first-generation learners. This goes against the culture of free interaction and absence of force as embedded in tribal ethos and culture prevalent at home. This has led to sharp division between home and school leading to lack of interest among the children towards school, and research findings have shown this as a major factor behind non- enrolment.In this paper special consideration certain ethnic minority groups, traditionally re- ferred to as tribes or tribals, as Scheduled Tribes (STs) who constitute around 8 per cent of the total population of the country.
