As the demand for an evidence-based approach to coaching grows, so does the need for rigourous outcome measures. However, despite the fact that coaching is a goal-focused process, there has been little discussion in the coaching literature about different approaches to measuring goal attainment. Given that goal attainment represents a key dependent variable for coaching interventions, it is important that this gap in the literature be addressed. This paper seeks to stimulate discussion about this important issue by describing an approach to the measurement of goal outcomes, Goal Attainment Scaling (GAS), and discussing the strengths and limitations of the approach. Whilst goal attainment processes are multifaceted and measurement is complicated by a multiplicity of goal constructs and the inherent instability of goals, it is argued that the GAS methodology offers coaches a way of neutralising some of these challenges. In addition, GAS has the potential to stimulate dialogue between practitioners and researchers, as it could provide a methodological framework and language accessible to both.

Keywords: Coaching outcomes, goal attainment scaling, methodology, practitioners, researchers.
