The International Early Learning and Child Well-Being Study (IELS) assesses children at age 5, measuring key learning and development outcomes. The overall purpose of IELS is to help countries to better support the development and overall well-being of young children through improved early learning experiences. It achieves this by: providing robust empirical data on children’s early learning; identifying factors that enable and inhibit children’s early learning; and informing early childhood education centres and schools about skill levels of five year old children, as well as related contextual factors, which could be used to make more informed decisions about curriculums and pedagogical methods. IELS focuses on three developmental areas: a) emergent literacy and numeracy, b) self-regulation, and c) social and emotional skills. IELS is an initiative of the Organisation for Economic Cooperation and Development (OECD) and its international administration is undertaken by a consortium led by the Australian Council for Educational Research (ACER), and including the International Association for the Evaluation of Educational Achievement (IEA), and cApStAn.
