The purpose of this paper is to expand the competence-led structuring and understanding of sustainability education by analysing the practices of professional individuals who have completed university education geared to the development of sustainability change-makers.,The research scope was initially on examining professional practices following the boundary work theory. Social practice theory was used as a methodological approach in conducting and analysing thematic interviews with 19 sustainability-focused master’s programme alumni. The interviews were analysed against the theoretical framework while also noting findings that fell outside of this framework.,A framework for understanding materials, competences and meanings of practices connected to the professional field of sustainability was introduced. The framework suggests that in the practices of sustainability-educated professionals, meanings emerge as a top priority and are conveyed using position-based materials and various complexes of competency.,The authors suggest that boundary theory informs well the emergence of the professional field of sustainability, and the utilisation of a practice theory furthers the understanding of sustainability professionalism and its education.,The authors’ suggest that practice theory could thus provide deeper insights on how sustainability science alumni use their education after graduation, how they practice their profession and in return offer applicable reflections to sustainability education.,Research using practice theory in reflection on sustainability education and the professional practice of sustainability has not been widely conducted and in the authors’ opinion brings value to the education and practice of sustainability and to the research of sustainability education.
