The publication explores survey implementation, data collection processes, response rates, and the weighting procedures used to ensure representativeness. It also introduces the datasets generated and evaluates their informative value at both federal and state levels. This work is part of a broader initiative to monitor and improve ECEC systems, involving contributions from policymakers, researchers, and practitioners. Designed for scholars, policymakers, and professionals in education and social sciences, the report emphasizes evidence-based approaches to enhancing ECEC quality.$7Generated by AI. 606 $aTotal quality management 615 0$aTotal quality management. 676 $a658.562 700 $aSchacht$b Diana D.$00 701 $aGedon$b Benjamin$01788937 701 $aGilg$b Jakob J$01788935 701 $aKuger$b Susanne$01788938 801 0$bMiAaPQ 801 1$bMiAaPQ 801 2$bMiAaPQ 906 $aBOOK 912 $a9911002572303321 996 $aERiK Methodological Report II$94379279 997 $aUNINA
