Working for the chair of the foreign language and methodology in Volgograd State Academy of Advanced Training and Retraining of Education Workers for about 4 years, the author has noticed that on the one hand, teachers of English have a reluctance to speak English in front of their colleagues (peers) while harboring an unwillingness to have any lessons for development of their linguistic competence. On the other hand, they are isolated while back at school and have little to no time, to work on improving their English. Despite the increase in number of courses aimed at the professional development of teachers of English, there remains a lack of availability of the ones designed for teachers' language development. Not only does the administration of the state schools feel that their employees will benefit more from courses with a goal of language development, but, teachers themselves realise the advantages of such courses. The main idea of this article then is to focus on the specially-designed course in In-Service Teacher-Training Academy that helps language teachers to advance their proficiency in English.
