“Ninth of October Public School” is a K-12 school located in Alcacer, Valencia. Approximately 420 students from kindergarten to grade 6 from low socio-cultural and economic background attend our school and we have over 30 faculty members. The centre offers bilingual education in Valencian and Spanish and it has adopted a multilingual program to teach non-linguistic subjects through English. This Erasmus + KA1 project arises from the need to have more teachers certify to teach subjects in English to implement our multilingual project; therefore the main objective of the project was to train teachers linguistically and methodologically to expand the supply of non-language subjects taught in English at all grades thus improving the quality of language teaching and contributing to the development of linguistic and intercultural competence of all students at the school. Another objective was to establish contacts with teachers from other countries to carry out projects in the future and to contribute in this way to internationalize our institution incorporating the European dimension. The eleven participants in the twelve mobilities of the project (4 kindergarten teachers; 3 primary teachers and 3 specialists) together with the other teachers of the faculty have demonstrated their commitment to introduce English as a language in their classes and to carry out the School’s European development through its participation in the various activities planned during the two years period.
