Interest in forms of assessment in modern, competency-oriented foreign language teaching has significantly increased in recent years; this applies to both standardized high school exams and language proficiency assessments in the classroom. The study book provides a solid introduction based on language testing research, illustrated with practical examples, and presents a practice-oriented and cross-linguistic discussion. Educators will become familiar with the theoretical principles of assessment and evaluation while simultaneously gaining concrete examples and implementation knowledge, enabling them to create and assess task and test formats for various language skills and competencies. At the end of each chapter, the book offers references to introductory and advanced specialized literature.
