Innovations are changing everything from school culture to student assessment. Changing educational needs of the student and advancement in technology has widened the area of responsibilities of teachers. Pre-service and in-service teachers training became crucial in this aspect. However, studies in field of teacher education point towards various lacunas in pre-service as well as in-service teacher education. In a bid to robust education system in national Capital, the Government of Delhi, began reforming school education in Delhi in 2015 by designing and successfully implementing large scale programs. Placement of Teacher Development Coordinator (TDC) in each school is one of such initiative introduced by Delhi Government through SCERT in July, 2017 as part of the flagship programme of Mentor Teachers. The vision of this programme is to create a collaborative network of teacher-educators for professional development of all teachers teaching in DoE (Directorate of Education) schools for creating 'An education system where everyone learns together'. This programme was started with a view to strengthen the culture of sharing teachers' best teaching practice in the school system, and to identify and work on the specific needs of teachers in particular school to further strengthen the learning of all students. This paper presents a comprehensive understanding of Teacher Development Programme- an innovative project stated by Delhi Government.
