The purpose of this final chapter is twofold: (1) to provide the synthesis of learnings on quality in teaching and teacher education on the basis of the analysis and discussion of the fourteen chapters collected in this monograph, and (2) to discuss implications for future research on quality in teaching and teacher education, policy and practice. In so doing, we ask: What do we know about quality in teaching and teacher education from the collected chapters and how can these findings inform future research, policy and practice in these areas? In order to answer these questions, the chapter is divided into five main parts. In the first part we identify a call that is present in all chapter: to move beyond a reductionist notion of education. In the second part we recognize the growing attention for teaching quality both as a blessing and a burden. In the third part we identify seven key dilemmas that arise from the different chapters. Next we use these dilemmas to identify implications for teacher education practice, policy and research. We conclude this chapter with some final reflections.
