Teacher education means professional preparation of teachers. It is not merely training of teachers but it is something deeper than mere teacher-training (Deb, 2004). It means the acquisition of knowledge, skills and ability which helps a teacher to discharge his professional duties and responsibilities effectively and efficiently and also reshaping the attitudes, habits and personality of teacher. But as per NCTE Act 1993 the term "Teacher education" means programmes of education, research and training of persons for equipping them to teach at preprimary, primary, secondary and senior secondary stages in schools and includes non-formal education, part-time education, adult education and correspondence education.
