The evaluation process generates not only procedures of assessment, but also negotiation of evaluation questions, criteria, indicators and, first of all, purposes. All participants in the process have their specific roles, rights and elaborate design of evaluation. Such approach to evaluation studies makes this type of research deeply involved in personal and social interaction of the participants and animates developmental resources of particular communities. That is why evaluation as an “invitation to development” is an important component of organizational and educational culture of each school. At the same time the process could be used in a very instrumental way to control and even manipulate the procedures and its results as a strategy of bureaucratic management.
