State leaders Markus Söder said on Friday that the first 11 million of the DIY tests had already arrived and would now be distributed through the state.

“It’s no good in the long run if the testing for the school is outside the school,” Söder told broadcaster Bayerischer Rundfunk (BR) during a visit to a school in Nuremberg.

“Contrary to what has been planned in Berlin, we’ve pre-ordered in Bavaria: for this year we have 100 million tests.”

Bavaria, Germany’s largest state in terms of size, plans to bring all children back into schools starting on Monday.

However, high coronavirus case rates mean that these plans have had to be shelved in several regions.

In Nuremberg, the state’s second largest city, primary school children have been sent back into distance learning after just a week back in the classroom.

The city announced on Friday that schools would have to close again after the 7-day incidence rose above 100 per 100,000 inhabitants.

The nearby city of Fürth closed its schools after just two days of classroom time on Wednesday, after the 7-day incidence rose to 135.

The Bavarian test strategy plans for school children to receive one test per week, while teachers have the possibility of taking two tests a week. The testing is not compulsory.

But teachers’ unions in the southern state have warned that the test capacity only exists on paper and have expressed concern that their members will become infected in the workplace.

“Our teachers are afraid of infection,” Almut Wahl, headmistress of a secondary school in Munich, told BR24.

“Officially they are allowed to be tested twice a week, we have already received a letter about this. But the tests are not there.”

BR24 reports that, contrary to promises made by the state government, teachers in many schools have still not been vaccinated, ventilation systems have not been installed in classrooms, and the test infrastructure has not been put in place.
