The Austrian business schools have an important educational and social function but their reputation has become worse in the last few years. This change was caused by different demographic and social processes and poses new challenges for teachers. Especially problems with language as a consequence of the general increase in immigration lead to worse performances of pupils. Another problem is the high dropout rate in the Austrian business schools, particularly concerning immigrants. The research question tries to examine the effects of these and other challenges on the educational function of teachers. The first chapter describes curricular and historical facts about business schools as well as the main changes and the resulting challenges. In the following chapter, theoretical foundations of the concept of education are provided and the main educational institutions - family and school are presented. The next chapter examines the role of teachers and their educational function. Furthermore, possibilities for education and also prevention measures are defined. It has been proven that a good teacher-student relationship and also the teacher personality can have a positive educational influence but can only be partially learned. Self-reflection and intercultural competences are important personal characteristics for teachers to counteract the new challenges effectively. Currently, teachers are supported by the introduction of the new curriculum 2014/15 for business schools. The changes in this curriculum should improve the situation of business schools in general and also the teachers function in education. First successes have been shown by the evaluation of the school pilot project Praxis HAS.
