“Der Schulzwang wird fallen wie die Berliner Mauer” (source: Bildungsvielfalt) stands for Compulsory education will eventually [sic] fall like the Berlin Wall. This has happened now.
Now, without further ado in response to the COVID-19 outbreak, homeschooling is suddenly the norm. Everyone in Germany is getting home schooled – without any bureaucracy.
1919 saw the beginning of Compulsory Education (Schulpflicht) in Germany. Over the years, there had been various appeals by individuals and petitioners to change the law.
In April 2010, a petition signed by 5400 people, was submitted to the German Bundestag asking for impunity for parents who teach their children at home. This petition was turned down in November 2011.
I had supported this petition back in 2009, and had published this post: Petition for Homeschooling in Germany
Homeschooling in German: der Hausunterricht or der Heimunterricht
