This scoping review, conducted using the Web of Science database, particularly focusing on SSCI (Social Sciences Citation Index) papers, offers an academically analysis of the current research landscape in assessment literacy. Through synthesizing existing knowledge and identifying research gaps, this two-phase review offers valuable insights into student assessment literacy (SAL). Based on key findings presented in this Chapter, we suggest that future research directions should prioritize expanding the breadth and depth of understanding of SAL, with a particular emphasis on experimental and longitudinal studies to track the formation and development of SAL over time. Moreover, exploring innovative interventions by taking account of teacher AL and cross-disciplinary approaches can further enrich the landscape of assessment literacy by synthesizing SAL and teacher AL. These endeavors contribute to not only strengthening theoretical frameworks but also translating findings into practical applications, fostering effective integration of research and practice in educational assessment.
