The schools have no choice but to have the lesson taught. Thus, of the 6300 teachers who teach German, only 2600 have studied the subject. In mathematics, there are only 1365 out of 5400. Even more blatant is the difference in the natural sciences: here come to 5300 teachers used only 900, who teach “professionally”.
The devastating finding is not due to the current crossover problem. Because the newcomers made in the school year 2015/16, from which the numbers come, only a fraction of the primary school staff. In addition, the extent of the shortage of subject teachers has hardly changed in the last five years – which also applies to the weak results of computation and writing in Berlin. The combination of both was the reason why the education of the Berlin elementary school teachers was reformed : German and mathematics have been compulsory studies since 2014/15.
