IES Ramiro de Maeztu is a bilingual High School located in the Autonomous Community of Madrid, Spain. In the Compulsory Secondary Education English Section and Programme, lessons are taught both in English and Spanish, whereas in the German Section students attend classes in German and Spanish as well. There is also an International Baccaularate Programme established in our school and functioning since 1983. Nowadays 124 teachers give lessons to almost 2000 students. Next year, a new English Section in Baccaularate will be set up in the Spanish Baccaularate Section. The spreading of Bilingual Programmes to both Spanish Baccaularate and International Section requires an improving of the profesional and linguistic competences of the teachers involved in those programmes. Therefore a set of best practices must be implemented so as to get the standards of excellence we find in the leading schools of other European countries. Besides, the improvement of the language skills of those teachers who are not involved in Bilingual Education is also necessary to allow them to join in these Programmes. Therefore we are requesting this KA1 which will be applied to 10 teachers of our school. Two "job shadowing" actions will be developed in Schools of Excellence in Sweden and the Netherlands, which are partners of this Project, and also 4 mobilities are requested for teacher language trainings in United Kingdom. There will be three expected impacts: - first of all, the improvement of teaching and language competences in both bilingual and excellence Programs developed in our school. - Secondly, triggering innovation and new Bilingual Programmes in the Baccaularate and broader understanding af different education systems of the EU. - Finally, the establishment of a partnership association with some schools of Excellence in different countries of the EU could become developing a new project, such as a KA2, which would open the international mindness of our school.
