The educational foundation of Germany’s youth is showing significant cracks as data reveals a sharp rise in students being forced to repeat the first grade. This trend is most pronounced from those with a migration background, where language barriers and a lack of early childhood preparation are prevalent.

At the Nordmarkt elementary school in Dortmund, an alarming 97 percent of first-graders are forced to repeat the first grade, Focus Magazine reports. The primary drivers for this delay include a lack of basic skills and the fact that many children “hardly speak German.”

While Germany could always absorb a certain number of non-German speakers, the numbers have grown beyond the ability of educators. Now, nationwide, the statistics are stark and breaking records. Over 41,000 first graders across Germany are repeating their first year. Children with a migrant background — particularly those who did not attend daycare — are the most heavily affected.

Regional disparity is also high; in North Rhine-Westphalia (NRW), 22,894 students, equalling 6 percent of all students, repeated the grade last year, while states like Bavaria and Baden-Württemberg see rates as low as 1 to 2 percent. However, as states like Bavaria become more diverse, the future may also present increasing challenges for these states as well. Currently, native German speakers are a minority in 1 in 5 classrooms across Bavaria.
