This chapter summarises the key themes discussed in the preceding chapters, in particular how teachers and practitioners can maximise opportunities to develop student assessment literacy (SAL) based on our conceptualisation of SAL. Limitations of this short book are discussed as well. Then this chapter suggests the implications of the learned lessons with a view to recommend future directions for SAL research and practice development. In closing, this chapter reiterates the significance of SAL as a major driver for students’ development as self-regulated and lifelong learners, and its implications for teachers’ and practitioners’ continuous support for students towards this end.
