In this article, the authors examine how cultural beliefs relate to aspects of professional competence. Specifically, the authors focused on multiculturalism and colorblindness. The findings reveal that colorblindness showed a significant negative relationship with willingness to adapt teaching to a culturally diverse student body. The authors also found that multicultural beliefs were related to higher self-efficacy and higher enthusiasm for teaching immigrant students, to less agreement with negative stereotypes about immigrant students' motivation and backgrounds, and to having chosen the teaching profession specifically as a means to foster integration of immigrants in Germany.
