The study carried out by the Berlin-based Institute for Population and Development found that 30 percent of Turks and those of Turkish origin did not finish school and only 14 percent took the Abitur, or the final secondary school exam that is the required qualification for university. But more than 50 percent of those in other migrant groups manage to do the same, the report said.
The study, which Der Spiegel reported it had seen before its Monday release, compared for the first time the successful integration of individual migrant groups including those who have been naturalized in Germany. It has compiled a ranking of federal states based on the level of integration of its immigrants.
Immigrants of Turkish origin were also found to be the least successful in the labour market: they are often jobless, the percentage of housewives is high and many are dependent on welfare, the study said. The state of Saarland was found to have the worst record – 45 percent of its Turks had no educational qualification of any kind.
Reiner Klingholz, director of the institute, said language remained the key to education and successes.
“For too long we've been used to the fact that we have primary school classes in which 80 percent of the children don't understand German,” he said.
But Germany's Interior Minister Wolfgang Schäuble, a member of Chancellor Angela Merkel's conservative Christian Democrats (CDU), told Der Spiegel that the biggest integration problems would soon be solved.

“Just simply wait for another Christian Democratic Party-led government for the next four years,” he said.
