Academic achievement is assuming greater importance day by day, one reason for this is the tremendous growth of student’s population and competition. It forms the main basis of admission, promotion in a class, obtaining degree and getting job. For that there is a tremendous pressure on students to earn good grades. Home environment has a very important role in this regards. So far as the education of the child is concerned home is the first agency and parents act as a first educator. It is what parents do in the home that counts for learning development of children. The main objectives of the topic are to find out the significant impact of home environment on academic achievement of tribal region secondary school students.
