The action learning set (ALS) is an often-used tool in practice development to facilitate group reflection. As such, its use evolves in the hands of the participants as they become more comfortable with the process and as trust develops amongst group members. This paper aims to discuss the journey of one ALS over a 2-year period. It seeks to highlight the process of learning through an ALS and the complexity of making the process meaningful for the participants. The role of trust within an ALS cannot be overstated. This was an imperative factor in the overall effectiveness of the set. (Contains 1 figure.)
