Given the pressing, complex global challenges facing society, it is imperative that students are well equipped to contribute to solving problems in an informed, ethical and meaningful way. This is the basis of a global citizenship approach to education. In psychology education, a global citizenship education may look like "psychological literacy", which is an approach that considers how students can intentionally apply psychology knowledge and skills to personal, professional and societal goals. However, it is not clear whether students are aware and value this approach to their psychology education. Across three studies, we explored students' perception of global citizenship and psychological literacy. Study 1 (n = 202) investigated UK undergraduate students' perceptions of global citizenship education and found that while only 12.8% of students were familiar with the term, students value this approach. Students also identified challenges within the conceptualisation and subject-level implementation of global citizenship. We then focused in on the discipline of psychology; Study 2 (n = 117) demonstrated that 18.0% of psychology students had heard of the term psychology literacy. Despite this, similar to global citizenship, students valued and had the opportunity to develop the attributes that underpin a psychological literacy approach (e.g. the ability to apply psychology understanding to real world problems). Finally, Study 3 (n = 296) explored whether psychological literacy can differentiate students by discipline. We recruited students from psychology, mathematics, humanities, and English and investigated whether psychological literacy is unique to psychology students, or whether it constitutes a set of interdisciplinary outcomes more aligned with global citizenship. This found that most skills did overlap disciplinarily, but some (e.g., 'understanding mind and behaviour') uniquely differentiated psychology students from other disciplines. Taken together, these studies indicate that students value education that allows them to apply their psychology knowledge and skills to solving real-world problems.
