Since its independence, Madagascar has not been able to easily improve its economic situation. This situation is also reflected in the educational system. The economic incapacity justifies the long-term financial dependence of the Malagasy education system on international organizations. Despite this, the success rates in public schools are very low compared to those in private schools. The analysis of the results of a survey of a sample of 80 private school managers in the Antananarivo renivohitra Cisco, allowed us to detect the reasons for the success of the educational system of these schools. The pedagogical strategies and the management system that they have adopted play a major role in their performance. Discipline, culture, academic achievement, and the quality of educational services offered are the hallmarks of an effective private educational institution. At the same time, the experience of private schools in resource management, their organizational cultures and the satisfaction of their teachers, justify their performance.
