Our school has had an international aim and dimension for years. We have ben participating in international projects and exchanges and we are now on our way to start a bilingual stream in English. We already have a French stream and want to offer our sudents a new opportunity to develop better their communication skills in English because we want to upgrade them and give them the chance to achieve their full potential, both academically and socially. Entrepreneurship, personal initiative, ambition and access to employabilty can´t be guaranteed if language competence is not real. We perceive languages as a tool to unite citizens, a tool that enables communication and, hence, cooperation. But nothing can be done if communication is not provided. Languages , which are part of an undeniable human and cultural heritage, are to unite people, to bring people near other people and cultures. Good languages skills and competences are essential to get another important goal: our students´ feeling that they are part of Europe. To get this, our teachers also need to be updated , qualified and well trained. For this reason our European Development Programme searches to implement our English stream and also to foster the training for those teachers who teach in French and English. Consequently, this programme includes on the one hand, the training for English and French teachers and teachers of other fields who teach in these two languages. There have been three job-shadowing (two in Crema, Italy and one in Nay,France) and three structured courses (one in Montepellier, France and two in United Kingdom, one in London and another one in Edimburgh) All teachers involved in training and job-shadowing are experienced enough and they have great efficiency. They are committed with teaching in bilingual streams and committed with the school goals. For this reason we consider this Programme to be perfect for them. The benefits and impact we expect to get is the teachers´good training in the short term and a better school , and in the long term a more European school where the majority of students and teachers are fluent in at least three European languages.
