Professionals require decision-making skills as well as technical knowledge. One might assume that their university education prepares them for this role yet, and least for future audit professionals, traditional text--and lecture--methods dominate teaching practice. This Participation Action Research study develops with auditing students a practice-informed, computer-based and judgement-orientated learning programme. We seek to identify ways in which student engagement in such decision-making dilemmas can be created and improved. Logs, student-surveys and notes from an independent observer document the longitudinal process. Findings identify features that improve student engagement and a contribution of the project is in revealing the value of removing technical and in-class social barriers. Implications for nurturing higher-level learning and for serving professional curriculums generally conclude the study.
