The term is self-explanatory. It refers to the education a teacher receives after he has entered the teaching profession. The teacher may have received his professional education in a teaching institute or in a college of education but he continues his education and should possess three types of competencies as under:
1. Competency in academic field.
2. Competency in teaching methodology.
3. Competency in class-room interaction analysis and application.
Some teachers start their career as matriculate teachers and during the course of their stay in the profession improve their academic qualification. They do it through formal or non-formal channels of education. In this process they improve their professional qualifications also.
In addition to this, there are other programmes, educational, social administrative or concerning other innovative classroom practices in which the teacher takes vital part, in short, all the extra education which becomes an integral part of his in-service education.
This, he may receive at different institutions by way of refresher and other professional courses, and all the travels and visits which he undertakes.
All these no college or course can teach a doctor that entire he has to learn; his practice will go on gradually widening the sphere of his knowledge. What is true of a doctor is also true of a teacher, the lawyer, the painter the psychiatrist, the engineer and the sculpture.
Education of a person is his self-culture and self- improvement and the process will go on to the end of one’s life. Teacher-education is continuous growth in the capacity to teach.
