The concepts of sustainability and sustainability competence are controversial, complex, difficult to define and measure, and have varied meanings for different people and practices. Given the complex nature of sustainability, there is limited availability of paradigmatic frameworks to guide educators in assessing sustainability competencies. This paper introduces the Dispositions, Abilities and Behaviours (DAB) framework, which influenced the design of an intervention in 2013-2014 that profiled sustainability competencies among final year undergraduate students in a higher education institution. The results of the mixed methods study indicate that the DAB framework has good potential as a guide to educators or researchers in understanding and profiling sustainability- related abilities, attitudes and actions (areas of performance) of cohorts of students within higher education settings.
