Education helps to provide exposure and draw out the inherent abilities of an individual leading to holistic development. Thus, education is a process of an individual’s development. Home is the first school of an individual wherein parents play a major role.. Different psychologists have categorized the age limit of an individual stating the different stages.  The child takes admission in the school and gradually it becomes a second home. The teacher plays a role of the parents. The task becomes even more challenging since the teachers play a role of ‘counsellors’, ‘guides’, ‘parents’ and ‘teachers’ of not one but many students.
