To complete the school team, eTwinning was searched for the most suitable ones with the idea of jointly and complementarily developing a project on the use ofthe CLIL methodology in bilingual teaching, prioritizing the development of materials and didactic proposals for the classroom, from the strengths that each partner country has as a result of its previous experience.
