Abstract : The diagnosis of the Guinean educational system during the states general of education at the end of the 1980s showed the necessity of carrying out qualitative changes within itself. Since then, it has been subject to several reforms. The main objectives of the first one are the following: i) the restructuration of the system,ii) the improvement of the teaching and training quality;iii) the reinforcement of management, planning and educational administration capacities. Concerning the administration and the educational system management, it has been noticed that inspite of real recovery efforts, it remains a lot to do in order to reinforce the coordination and to make the decentralization more operational. Because, in spite of the putting in place of the decentralized structures, their autonomy as far as decision making is concerned has proven to be insufficient in addition to the lack of regular circulation of information, all of this constitute an obstacle to the good running of the system. From what preceeds, we can conclude by saying that the improvement of the guinean educational system just like the future of the school administrators in general and the institution heads in particular depends on a political decision which is in the hands of the educational authorities. They will be what they want them to be.
