Book excerpt: The European Portfolio for Student Teachers of Languages is a tool for reflection and self-assessment of the didactic knowledge and skills necessary to teach languages. It builds on insights from the Common European Framework of Reference and the European Language Portfolio as well as the European Profile for Language Teacher Education. Four years after its initial publication it has been translated into twelve European and Asian languages.To meet widespread demand this ECML publication provides materials which support its implementation in teacher education. The book entitled Using the European Portfolio for Student Teachers of Languages presents examples, discussions and research findings of how the EPOSTL is used in initial teacher education courses, in bi-lateral teacher education programs and in teaching practice. The accompanying folder and flyer feature, amongst other things, guidelines for strategic measures for introducing the EPOSTL in a particular institution.
