The educational disadvantages of migrant students are a persistent problem in many Western countries. Against this background, policymakers often call for more diversity in the teacher workforce, arguing that migrant students might benefit from being taught by migrant teachers. Despite the popularity of this claim, there is almost no research-based rationale for increasing the diversity of teachers in Europe. This paper is a step toward filling this research gap for Germany, aiming to assess whether migrant teachers reduce ethnic educational disadvantages. Our analyses are based on a nationally representative large-scale assessment of ninth graders that provides information on the migration status of both students and teachers, with achievement tests and teacher-assigned grades in German as dependent variables. The results run contrary to widely held expectations, indicating little evidence that migrant students benefit from being taught by migrant teachers.
