Schloss Bieberstein is a private boarding school situated near Fulda (about an 1.5 hours drive from Frankfurt/Main). It can be found in an old castle on top of a hill, with the nearest village in walking distance.
Bieberstein is home to about 120 students aged between 14 and 20, who are organized in so-called “family groups” of up to 12 students. Each group is supervised by a teacher living on campus with the students. Since the relationship between teachers and students is closer than in state schools, students and teachers call each other by their first names and use “du” instead of “Sie”.
