Restructuring is examined in this article, not as the official educational policy of decentralization, autonomy or change of the form of the accountability of school systems, but as a homeostatic answer of a school system to important changes that are happening to its ecology. It is about a case study concerning the transformation of an one-culture demography of a school system in the Cypriot Educational System. Through ethnographic methods of observation, interviews, official documents and data analysis in the depth of time, the impeding changes that the “unexpected” multicultarism of the student population brings to the structure of the school system and their diffusion in the higher administrative levels of authority are being examined. The results show a new theoretical perspective: that of the operation of restructuring as a homeostatic change of the elements of the structure of a school system spontaneously, as a dynamic bottom-up change in the centralized Cypriot educational system.
