Environmental and sustainability problems are not purely technical problems. Many of the most pressing issues, such as climate change, resource scarcity, and pollution, require holistic approaches that go beyond technical systems analysis and optimization. Such problems have been called wicked sustainability problems (WSPs) because they are highly complex, contested, and lack definite solutions 1,2 .Engineering education has the potential to play an important role in preparing students to contribute to deal with problems such as WSPs 3,4 . To be able to contribute in this way, students need to develop an ability to holistically and integratively understand and address WSPs while considering the normative context of sustainable development (here called WSP literacy). However, common practice in engineering education more commonly prepares students to address well-structured and tame rather than wicked problems 5,6 . One reason may be that working together to develop complex competencies such as WSP literacy is challenging for students as well as educators. Wiek, Withycombe, and Redman suggest that formulating and operationalizing intended learning outcomes (ILOs) for complex competencies can facilitate this difficult process and thus improve engineering education practice 4 .In this paper, we provide a preliminary matrix of 22 concrete ILOs for WSP literacy, as well as two different approaches to assessing (some of) them in engineering education. We expect that engineering educators will find these ILOs and assessment strategies valuable for adopting a constructive alignment approach for WSP literacy in their teaching.
