This report presents the outcomes of Phase 1 of the Spanish National Chapter of the Coalition for Advancing Research Assessment (CoARA), coordinated by ANECA, CRUE, CSIC, and ISCIII. It maps emerging institutional approaches to research assessment reform across Spanish universities, research centres, and evaluation agencies. Based on contributions from over 60 institutions and the work of four thematic working groups—assessment methodologies, assessment criteria, interdisciplinarity, and awareness and training—the report identifies shared trends, methodological innovations, and challenges in implementing responsible and context-sensitive assessment practices aligned with CoARA principles. The findings will inform the next phase of the Chapter's work, focused on developing shared recommendations and strengthening institutional capacity.
