This paper provides an overview of the Security Council’s focus on children and armed conflict and how the mechanism established under the auspices of the Security Council has provided an avenue for the more effective implementation of international standards relevant to children. On the one hand, the paper is specifically focused on the work of the Security Council Working Group on children and armed conflict, and its conclusions, and how these have pushed the implementation of relevant international instruments. On the other, the paper looks at the implementation of this mechanism in the field and the development of action plans with armed groups and forces that recruit and use children. The paper concludes that while there has been much progress for children who have been recruited and used by armed forces and groups, much more could be done to make the most of this mechanism. For instance, information gleaned through the Security Council mechanism could be used to inform various transitional justice mechanisms such as the ICC. The narrow scope of child recruitment has provided a useful entry point, but the time has come to take the agenda to the next level.
