The Atlaas project focused on improving communication skills in foreign languages, one of the eight key competencies defined by the European Reference Framework. It aimed to enhance the ability of adult learners to understand, speak, read, and produce texts in foreign languages while enabling teachers and trainer to foster positive attitudes toward cultural diversity and intercultural communication. Recognising the essential role of language skills in facilitating mobility, employment, growth, and social participation across Europe, the project supported national and European strategies to promote language learning through Erasmus+ activities.
