In January 2023, the Governing Council of the Universitat Jaume I unanimously approved its adhesion to the Coalition for Advancing Research Assessment (CoARA). This agreement – adopted by the vast majority of Spanish universities and by the National Agency for Quality Assessment and Accreditation (ANECA) in April 2023 – involves the adoption of an action plan for the progressive reform of internal research assessment systems, a commitment to be completed within five years (January 2028). This document defines the CoARA action plan for the Universitat Jaume I. The plan is drawn up with the aim of improving the quality, execution and impact of research at the Universitat Jaume I and includes the principles on which the assessment criteria and processes should be based, i.e. quality and impact, diversity, inclusion and collaboration.
