Studies have found that non-native speakers of English in the UK have no causal impact on the performance of other pupils, immigrant children have no significant impact on the test scores of Dutch children, no effect on grade repetition among native students exposed to migrant students in Austrian schools, that the presence of Latin American children in schools had no significant negative effects on peers, but that students with limited English skills had slight negative effects on peers, and that the influx of Haitians to Florida public schools after the 2010 Haiti earthquake had no effects on the educational outcomes of incumbent students.
