High-quality all-day schooling offers major educational benefits to students. At all-day schools that are more living space than mere place of learning, teachers and educators have a better idea of and means to respond to the social needs and different learning abilities of their students. This is why we advocate the establishment of nationally standardized quality criteria for all-day schools in Germany. The study “Daring to Educate More – Recommendations for Better All-Day Schools” conducted on behalf of four foundations – Bertelsmann Stiftung, Robert Bosch Stiftung, Stiftung Mercator, and Vodafone Stiftung Deutschland – constitutes an initial contribution to the discussion about nationwide quality development.
