Nowadays, teaching requires scientific, pedagogical and didactic quality, as well as knowledge and capacity for educational management and administration. To be a teacher is also to share the management and administration of the school organisation. The current teacher has to think about education, share and negotiate with his or her peers and, to do so, must have leadership skills. MAGE is an excellent opportunity for the training of middle and top leadership because it is a useful and timely “time” to “think” education and its management forms. The MAGE student has a magnificent opportunity to build a grounded knowledge, to learn to reflect, to investigate, to design and implement research projects.
