Teaching immigrant children is becoming a critical issue e.g. in 2009/2010 academic year there were 17.6% of pupils registered in Austrian schools had a first language other than German; in Greece the percentage of non-native pupils in primary and secondary schools has risen from 7.3% to 12% in the past five years.
Sisserändajate laste õpetamine muutub aina olulisemaks; nt 2009/2010. õppeaastal oli Austria koolides registreeritud õpilastest 17,6 protsendil esimene keel muu kui saksa keel; Kreekas on viimase viie aasta jooksul alg- ja keskkoolide muud kui kohalikku päritolu õpilaste osakaal suurenenud 7,3%-lt 12%-le.
