This study explores how adolescent clients construct the purpose and outcome of counselling. A narrative analysis was performed on interviews with 22 clients (aged 16--18) who had used a school-based counselling service. The aim was to identify the purpose and outcomes that participants attributed to their counselling experience. The analysis identified four narrative forms that young clients used to describe counselling. These included "transformative", "supportive", "pragmatic" and "disappointed" narratives. Each narrative form constructed a different purpose and outcome for counselling. Engaging with clients' narratives about the purpose and intended outcome of counselling may allow counsellors to better match their expectations and approach to fit with their young client or to work with them to co-construct more flexible narratives that support helpful outcomes.
