“…The survey focusses on the characteristics of ECEC settings considered significant by societies and policy makers, as well as the research perspective on high-quality pedagogical activities, well-being and successful learning (Anders et al, 2012, Pianta et al, 2005, Pianta et al, 2009, Siraj et al, 2015, Tietze et al, 1998, Tietze et al, 2005, Hilbert and Eis, 2014, Leseman et al, 2017. It particularly focuses on aspects supported by research findings as being significant for the development, well-being and learning of children from diverse family and cultural backgrounds (OECD, 2018, Burchinal et al, 2011, NICHD Early Child Care Research Network, 2006, Siraj-Blatchford et al, 2003, Hilbert and Eis, 2014, Leseman et al, 2017. To capture the diversity of factors in different ECEC systems, the survey collects data on a wide range of variables in a standardised format to ensure comparability.…”
