„The proportion of underachievers in reading among pupils with a migrant background is much higher than for pupils without a migrant background in many EU Member States. […] The situation is usually worse for pupils born abroad (their underachievement rate exceeds 50 % in Greece, Germany, the Netherlands and Sweden) than for native-born pupils with parents born abroad.“
