The Research Assessment Exercise (RAE) is a systematic evaluation of the quality of research conducted at higher education institutions. It aims to assess the research output of universities in a fair and transparent manner, providing a framework for measuring academic performance. The RAE helps allocate funding and resources based on research quality, influencing institutional strategies and priorities. Conducted periodically, the RAE involves peer review by experts in various fields. The results inform government policy and funding decisions, impacting institutions like UK universities and their research capabilities. The exercise ultimately aims to enhance the overall quality of research in the academic community.
