Via YLE:
Nearly half of Finnish teachers believe that the proportion of immigrant children in any one class should be limited to 20-30 percent.
41 percent of teachers questioned by Oppettaja-lehti, a teacher’s magazine, would like to limit immigrant numbers in schools and daycare. Almost a third of those polled said that they would not support quotas.
Three out of four teachers say that immigrants should be dispersed across the country, to avoid concentrations of immigrants in certain areas.
