This means that, from three to eighteen, the educational process of children will be governed by the same principles and will follow the same methodology. This unit and this coherence are guaranteed because in the different educational stages the different programs endorsed by the International Baccalaureate Organization are applied. That is to say, in Primary and Infantile the Program of Primary School; In Secondary, the Middle Years Program and in Baccalaureate, the Diploma Program.
