The article defines a teacher's mission in the era of social turbulence and high uncertainty, which characterize the transition of Russian society to the post-industrial stage of development. The lack of scientific ideas about the professional resources and personal potential of a teacher, the ways of scientific and methodological support of teacher's development in modern conditions determine the purpose of the work, which is to identify the most demandable professional resources in the context of a teacher's personal potential development in the era of social turbulence and transformation of education. The authors propose a model of teacher’s professional resources and personal potential, identify diagnostic methods for its studying, and determine the possibilities of additional pedagogical education in the development of a teacher. The authors conclude that it is necessary to improve the process of teachers’ professional development and retraining, taking into account the current requirements for a teacher's activity and level of competence. The experience of the Ulyanovsk State Pedagogical University in organizing comprehensive support for the development of teacher’s professional resources and personal potential, in managing teacher’s career, in developing advanced professional programs and professional retraining during additional professional education is presented.
