ABSTRACTChild protection and welfare systems are entrusted with significant power by governments and are therefore a significant focus of monitoring activities. Monitoring can help to build a better child protection system and to ensure child safety; track policy and legislative implementation and resource allocation; contribute to preventing systemic ‘failures’; provide data for system, policy, and legislative reforms; and support continuous improvement. The Irish system is worth examining for three reasons. First, Ireland has had a single state‐provided child protection and welfare service called the Child and Family Agency. Second, the system has been through a sustained period of development. Third, Ireland has one dedicated statutory authority called the Health Information and Quality Authority (HIQA). This article provides a case study of the strategies and mechanisms adopted by Ireland to monitor the operation, quality and development of its child protection and welfare system. We will show that there is significant direct and indirect monitoring and focus on child protection from regulators, civil society organisations, government agencies and committees and independent actors. Such monitoring has significantly influenced the development of policy, practice and the development of the child protection system in Ireland.
