The modern teaching system has changed the traditional meaning of teaching. Today, the teachers are dangerously overloaded because traditional functions of instruction, socialization, evaluation and classroom management are not regarded sufficiently to make them effectively.

Teachers are facing a flux in the educational scenario which contains innumerable and complex situations. There are unstable home and community conditions for children from all social classes, poverty and hunger and the classroom becomes a mirror of society’s varied problems. Now the role of a teacher has been completely changed.

He/she has to manage resources, curriculum, co-curricular activities, examinations, innovation and changes, time, conflicts etc. Evaluation of a teacher’s performance becomes significant, to identify the strengths and weaknesses of the system.

The need for appraisal of teacher effectiveness becomes significant in the context of the resources that society allocates to education society has become particularly concerned with the failure of the education system to contribute to its socio-economic development.
