The WiDaF certificate (German as a Foreign Language in Business) was developed in 1996 by the Franco-German Chamber of Industry and Commerce and serves as a standardized German test of job-related language skills. Thus, the WiDaF helps companies as a reliable tool to assess the German language skills of foreign-language employees and applicants. There is no better way than the WiDaF to prove your language skills on the job market. In this way, you show your future employers that you are up to business negotiations, correspondence and other everyday situations in German professional life.
