The brief synthesizes evidence on why early childhood intervention is an essential component of effective ECD systems, highlighting the consequences of delayed identification and fragmented service delivery. It presents key principles for system design, including inclusiveness, family‑centred approaches, cross‑sectoral coordination, and long‑term sustainability. The document focuses on policy levers rather than service models, making it applicable across diverse national contexts

The guide outlines key concepts, research questions, and methodological steps for assessing early childhood intervention systems at national level. It supports the collection and analysis of qualitative and quantitative data across sectors such as health, education, and social services. Emphasis is placed on understanding governance structures, service availability, access, quality, workforce capacity, and coordination mechanisms. The guide is designed to ensure consistency, rigor, and comparability in national analyses, while allowing adaptation to country contexts.

The paper documents how early childhood intervention services in Croatia and Serbia have adopted family‑centred principles, including active caregiver involvement, coordination across sectors, and individualized support for children with developmental difficulties. It illustrates how services have been adapted within existing institutional systems rather than developed as stand‑alone programmes. The focus is on practical implementation within real policy and service contexts.

The paper synthesizes evidence from neuroscience, biology, and public health to explain how early experiences influence the development and interaction of multiple body systems, including the immune, metabolic, and stress response systems. It demonstrates how early adversity can contribute to preventable chronic diseases and mental health conditions later in life. The analysis links ECD directly to long‑term health outcomes and health system costs.

The report examines how child development monitoring is integrated into primary health care services across countries in Europe and Central Asia. It reviews existing policies, practices, and tools used to assess developmental progress in early childhood, identifying both strengths and gaps. The publication emphasizes the importance of early detection, timely referral, and continuity of care within routine health services. It provides practical directions to strengthen systems, workforce capacity, and data use to support early childhood development.

This report explores the largely unmeasured consequences of the COVID‑19 pandemic on early childhood development in the WHO European Region. It reviews disruptions to essential services such as health care, early learning, childcare, and family support, as well as increased stressors on caregivers and households. The analysis highlights significant data gaps and missed opportunities to monitor, protect, and prioritize young children’s development during crisis response and recovery. It calls for stronger systems, better data, and child‑centred policies to mitigate long‑term developmental and social impacts.
