For a preliminary exploration of management models between two secondary schools, a Delphi method was used in order to identify and focus relevant topics for a larger research. A first approximation with this method proved to be a heuristic tool to focus and define some categories and guidelines of enquiry. It was found that in both of the schools explored, teachers and non-teaching staff assign a similar set of priorities to dimensions of management: first priority is assigned to principal`s leadership, different internal relations come in second and external affaires come at last. When teachers' answers are separated from non-teachers', in the school with better academic results, the former assigned a first priority to teachers' updating. From these results, different narratives could be constructed. [For complete volume, see ED567040.]
