This article presents the results of the diagnostic process carried out by the Iberarchivos Program in 2023, aimed at strengthening archival and gender equality policies in national archives across IberoAmerica, within the framework of the Sustainable Development Goals (SDGs) of the 2030 Agenda. The study focused on strategic areas such as transparency and access to information, electronic records management, archival legislation, gender policies, institutional evaluation, and monitoring mechanisms. A sample of 17 national archival institutions was analyzed to produce a comparative characterization of their organizational structures and personnel policies. The analysis identified good practices, common challenges, and regional trends that reflect the degree of maturity in the implementation of public archival policies. The article seeks to share the main findings of this research and to present the specific methodology developed, centered on a maturity model designed to assess archival and gender-related policies. The model’s conceptual foundations, analytical dimensions, and applications in strategic planning, institutional evaluation, and regional cooperation are described. This tool contributes to strengthening documentary management capacities in the region and promoting inclusive and sustainable policies, in line with the principles of UNESCO’s Memory of the World Programme.
