German politics has a word for an agreement not to reopen a school system: Schulfrieden, school peace. In December 2008, the SPD, the Greens, the CDU and the FDP in Bremen agreed to take no initiatives for ten years that would substantially change the school structure they had just reformed. The Bremen SPD chair argued in March 2018: Es war und ist richtig, den Streit über Schulstrukturen zu beenden. (It was and is right to end the dispute over school structures.) In 2018, the leaders of the SPD, CDU, Greens and Left agreed to continue the agreement. The structure was not to be touched in den kommenden zehn Jahren bis 2028, in the coming ten years, until 2028. In North Rhine-Westphalia, the red-green government and the CDU opposition agreed on a school peace in 2011 that was meant to hold until 2023. In August 2026, the CDU group in Bremen, now in opposition, called for a new agreement after 2028: Nicht der Konsens ist gescheitert – der Senat ist bislang an seinem Vollzug gescheitert. (The consensus has not failed. So far, the city government has failed to carry it out.)
