This research explores teacher leadership as a necessary skill in modern education. First, the foundations of teacher leadership were addressed through three axes: the definition of the concept, the essential skills of the teacher leader, and the different leadership styles. Then, the impact of this leadership on students, particularly on their motivation and personal development, as well as on the school, particularly through the commitment of the teaching team and the evolution of educational programs, was analyzed. On a practical level, an observation grid was designed to assess leadership mastery among primary school teachers. The results show gaps in the application of this skill and a notable variation between teachers specializing in educational sciences (LEE) and other teachers. To address this, concrete proposals are put forward, such as the integration of this skill into teachers' professional skills frameworks, in order to give it a central place in the evaluation and supervision processes.
