Language skills take up a central position in every European projects. Our school strategy of international openness is willing to involve staff teaching, other than language teacher, to acquire proficiency in foreign language to ensure our educative policy. Since our commitment in projects such as the Comenius project (AbeilHomXXI 212-2014) we have developed high quality relation with our Spanish partners : the IES Ángel Corella and the IES Sierra de Guadarrama (Comunidad de Madrid).. Using this network, the “Learning Mobility of Individuals” project for education and formation, will enable us to respond to this necessity. Two kinds of motilities will be established. The first one, during the Spanish school year, will be an opportunity to exchange and improve our knowledge of the Spanish educational system and culture. The second one, during the university summer school, will allow us to acquire deep improvement in Spanish language. At the end of this project, the reached level will be approved by the official accreditation of the degree of fluency of the Spanish language (DELE) The acquisition of strong knowledge in Spanish and culture is essential for our future European projects. It will permit deeper and richer exchanges with our Spanish partners, a crucial support for the project elaboration.
