Abstract: | There is an increasing demand on voluntary sector counselling agencies to evaluate the effectiveness of their work with clients. A pilot study was carried out in a voluntary sector counselling agency to assess the feasibility of adopting a well‐established evaluation system (CORE) designed to measure client outcomes. The paper describes the issues and complexities involved in introducing such a system, and explores the impact of the evaluation on counsellors, staff and users of the service. It is suggested that evaluation can play an important role within voluntary organisations in enabling counsellors and staff to reflect on their work. |
