n recent decades, the notions of leadership and governance have become invasive, polymorphic, and polysemous. Among other things, the interest in educational leadership has seen a surprising evolution in a short time. Educational management programs had to evolve until the departments themselves, and often their names, were transformed. It has also become relevant to examine the reality that this notion covers today. In education, some researchers suggest grouping all the management activities of a school within the notion of leadership. For others, everything is a component of leadership, including the context and the school environment. Thus, we can conceive three major phases in the development of the concept in education, which often remain present in hybrid forms: leadership as a personal attribute; leadership as a common process; leadership as part of a new governance of an education system. When it comes to educational success, researches show that teachers / teaching factors have a strong impact on student learning and educational success. Teachers are among the most important actors in influencing student success. Teachers' satisfaction with their relationships with school administration and human and material resources is positively linked to two well- known pedagogical practices to promote student success: teaching learning strategies and cooperative pedagogy.
