In response to a growing demand for more inclusive scientific environments, there emerged a need to revise the conventional metrics used in academic evaluations and resource distribution. This article investigates the development of Diversity, Equity, Inclusion and Accessibility (DEIA) indicators as fundamental tools for promoting fair metrics in science. The research was motivated by the urgency to create methods that not only assess but also foster a culture of equity, contributing to the modernization of metrics and encouraging the democratization of science. The aim was to propose practical and effective DEI indicators, aligned with principles of justice and accessibility. The adopted methodology included a theoretical-critical approach, supported by theories of intersectionality and Bourdieu's scientific field, and document analysis, which allowed for a detailed investigation of innovative practices. The results identified six indicators: composition of gender and minorities in leadership positions; diversity in publication authorship; equity in access to funding; retention and success rates of diverse student groups; organizational climate and inclusive culture; and engagement with underrepresented communities. These indicators provide a broad view of the challenges in implementing DEI principles, influencing the debate on policy reforms, and promoting more equitable and accessible scientific practices.
