Administrative Consultation Wiki (ACW) is a project run under the auspices of the Faculty of Administration and the Ministry of Public Administration in Slovenia since 2009. A crucial component thereof is the involvement of students of Master of Public Administration (MPA) degree programs to offer them an opportunity to develop competences in relation to problem-based learning. ACW has been established as a research project to resolve complex problems in real administrative procedures' practice. This article explores the results, hitherto missed opportunities and further challenges of MPA students' integration in ACW as a learning method for MPA graduates, based on the analysis of their expectations and achievements in 2013 and with special regard to the development of Tuning generic competences. According to the results of the study, the ACW project can be considered a role model in terms of both content and methodology, necessary for work in PA practice, learning and research.
