Book excerpt: The European Language Portfolio aims to foster the development of learner autonomy, intercultural awareness and plurilingualism. Teachers of particular languages working on their own can use the ELP to promote learner autonomy, but the goals of intercultural awareness and plurilingualism invite us to use the ELP in all foreign language classes at all levels in the school. The guide introduces the language education policy that underpins the ELP, explores the key concepts that it embodies, and explains how to plan, implement and evaluate whole-school ELP projects. The ten case studies published on the project website illustrate various dimensions of ELP use and include practical suggestions and activities for teachers and learners.
