As the participation of children and young people in policy decision-making has spread in the UK, participation work is facing hard questions on its translation from principle to effective practice. The participation literature has been largely self-referential in its consideration of policy influence. This paper considers the potential usefulness of the UK literature on policy networks, which categorises the relationships between government actors and other interests in policy-making. A brief introduction is given to this literature. Then a participatory project is examined in light of certain key concepts within the policy network literature. The paper concludes by considering how both the participation and the policy networks literature might learn from each other in future conceptual and empirical work.
