We find that dialect-speaking has a modestly negative effect on boys' language test scores. In addition, we study whether there are spillover effects of peers' dialect-speaking on test scores. We find no evidence for spillover effect of peers' dialect-speaking. The test scores of neither Dutch-speaking children nor dialect-speaking children are affected by the share of dialect-speaking peers in the classroom.}, keywords={spillover effects;test scores;dialect-speaking;language;academic performance}, }
