The project “Advancing the didactically relevant and linguistic skills of teachers” intended to deepen and enhance the intercultural and linguistic skills and thus the professionalism of teachers at the Theodor Heuss School Reutlingen. This was done in consideration of both the current and the future teaching assignment of the recipient. As one of the biggest vocational schools in Baden-Württemberg, the Theodor Heuss School is confronted with the changing demands of an increasingly unified Europe in what concerns teaching and education. This entails enabling a growing number of students to spend time abroad participating in school partnerships and mobility projects on the one hand. On the other hand, the intention is to prepare the teaching staff more thoroughly for the changing parameters. This was done in the context of the project “Advancing the didactically relevant and linguistic skills of teachers” in particular, which wanted to enable one colleague to attend a training course which matches her individual needs and abilities.
