This document discusses linking the Research Excellence Framework (REF) and Teaching Excellence Framework (TEF) through promoting research-informed teaching. It notes recent changes to REF and TEF that bring them closer together, such as REF now recognizing the impact of research on teaching. However, a dichotomy still exists between rankings that prioritize research versus teaching. The document proposes finding the "sweet spot" of research-informed teaching to help solve this dichotomy. It outlines different models of integrating research and teaching and argues this fusion can create a virtuous circle where each informs the other.
