Purpose: The purpose of this paper is to review and provide propositions about survey assessment tools of the key sustainability competencies (KSCs) of education for sustainability. UNESCO points out how education plays an important role in transforming societies towards a sustainable future and achieving the United Nations’ sustainable development goals. To plan education for sustainability, teachers need to know the students’ competencies for sustainability before they come to class. Thus, a formative assessment about student competence for sustainability is needed.
Design/methodology/approach: Firstly, a structured literature review of assessment tools used to measure sustainability competencies by questionnaire survey is presented. Secondly, the authors’ conceptualise how the competencies influence each other and provide propositions for future research.
Findings: The literature demonstrates that there is much ambiguity between prior research about the scales used and what they represent. A lack of validation across disciplines is apparent and an assessment tool that includes all eight KSCs could benefit education for sustainability. Future research could investigate how the competencies influence each other and which drivers are stronger for each discipline across different countries. A formative assessment tool can address this need.
Originality/value: The findings provide a new analysis about questionnaire assessment tools used in prior research to measure sustainability competence. The authors’ offer a discussion about the strengths and weaknesses found in prior research and propose suggestions for future research. Their conceptualisation also provides propositions for validating the KSCs presented in a recent framework.
