Adaptive technology in designing computerized educational systems is one of the major tendencies today. Student model here is the main component, on which adaptive course control is based. The paper is focused on a proposed approach to designing student knowledge model based on an expandable graph of concepts. The graph presents educational concepts and terms in a form of hierarchy. Each node is connected to related objects of computerized teaching system (e.g. chapters, pages, quizzes etc.). Thus, the system is able to track student’s level of knowledge of concepts from graph, node by node.  The proposed principle can be used to design  competence-oriented model of specialist knowledge.
