The concept of children's agency can be used to understand how children actively shape their lives. While in social work there is a growing body of research on how children experience meetings that involve collaborating professionals, little is known about the ways in which they exert an influence. The purpose of the study is, in a Swedish context, to investigate children's perceptions of their agentic capacity in regulating participation and exerting an influence on outcomes in interprofessional collaborative meetings. Interviews were carried out with 28 children in receipt of social services support. Findings revealed that children perceive professionals' talk as restricting opportunities for input. They also perceive that they have the capacity to exercise agency by (i) conforming to expectations by feigning boredom and seeming disengaged, but at the same time paying close attention; (ii) by using exit strategies; and (iii) by developing ‘in‐situ’ strategies to end meetings. Rather than, as previously suggested, being powerless in such circumstances, the children tell how they carefully assess situations, and, from a position of apparent subordination, talk of ways of acting that reveal their agentic capacity. These insights are of importance for practitioners who are encouraged to look beyond behaviours that first meet the eye.
