• Highlights • Parents with and without migration background differ in educational knowledge. • Parents with migration background have less educational knowledge on average. • Variations in educational knowledge by immigrant groups. • Social and cultural resources are central to explaining knowledge differences. • Acculturation strategies prove to be of little relevance. Abstract Although extant research persistently highlights the importance of information for educational decision-making, better understanding the existence of, and the underlying reasons for, informational differences between immigrant and non-immigrant parents is important. This study examines the differences in the level of information between immigrant and non-immigrant parents of third graders just before they make probably their most important educational decision in the German education system. We draw on approaches highlighting the importance of resources and parents’ acculturation to explain the informational differences between immigrant and non-immigrant parents. Employing linear regression and probability models on data from the National Educational Panel Study in Germany (N = 3961), we demonstrate that all immigrant groups, particularly those from Turkey, the former Yugoslavia, the Middle East, and northern Africa, are significantly less informed than parents without own immigration experience. This result is evident both in our overall test and in various domains of the test, which analyze different aspects of information relevant to parents’ educational decision-making. Furthermore, different endowments with social and cultural capital largely explain the informational differences between parents with and without an immigrant background. In contrast, different acculturation strategies are almost negligible in explaining the differences in the level of information. Our findings provide important insights for research on migration-related inequalities in educational decision-making and for developing interventions to improve migrant parents’ ability to make well-informed and thus intended educational decisions.
