Every human society always includes socio-professional groups, that perform major functions. In the contemporary context it is primarily social strata that form human capital. Most of these groups generally belong to the middle class. The structure of this stratum can be presented as kernel and periphery. Teachers should be included into the middle class croup according to nature of their work, functions and level of education. Otherwise, they would fail to perform fully their functions. The aim of this research was to emphasize conditions, factors, parameters that define position of teachers as representatives of the middle class in the Russian society. The work shows that the level of school teachers’ living standard and social comfort as well as the status of teachers clash with the accepted parameters of the middle class.
