A LinguaFolio is a self-directed, formative assessment tool that motivates and rewards language learning while documenting and informing students of their progress. It is based on European and American language standards and guidelines and contains three main parts: a language passport with self-assessments, a language biography detailing learning experiences and goals, and a dossier with samples of student work to demonstrate skills. The LinguaFolio is intended to support lifelong language learning for students of all ages.
