European Schoolnet shared a survey with its members to explore the extent to which national education systems are addressing well-being in digital environment in school. This report, published as part of the Agile Collection of Information series, presents a comprehensive overview, across 20 education systems, of national policies, curricular developments, teacher training initiatives, and monitoring mechanisms related to this critical issue. The findings reveal that while several countries have integrated well-being in digital environment in school within broader educational or public health strategies, dedicated national policies on the topic are also starting to emerge. Where policies exist, they are often influenced by international research, experiences of educators, and growing awareness of digital risks such as cyberbullying, screen overuse, and social exclusion. Integration of topics related to well-being in digital environment in the curriculum is common, particularly in primary, lower and upper secondary education, with many systems adopting a cross-curricular approach that emphasises digital citizenship, media literacy, and psychosocial health. However, early childhood education remains less targeted in this regard.
