On the basis of theoretical and empirical analysis of the main conditions for the creation of technologies, methodological requirements for the development of the process, the criteria for manufacturability are analyzed. The scientific substantiation of technology of development of professional culture of the heads of the out-of-school education institutionsin postgraduate pedagogical education as a system of logically sound operations aimed at achieving a certain goal diagnostically is given.
