This study delves into the intricacies of the Brazilian evaluation of graduate education, overseen by the Brazilian Agency for Support and Evaluation of Graduate Education (CAPES). Beginning with the inception of the evaluation mechanism in the 1970s, the research chronicles the evolution of this pivotal instrument in shaping the country's science landscape. Although the system has been crucial in fostering transparency, academic quality, and judicious allocation of resources, criticisms emerge regarding its emphasis on publication volume over academic and societal impacts and potential neglect of the training dimension. The analysis also sheds light on the challenges CAPES has faced, such as the threat of decommissioning due to political unrest and the repercussions of the COVID-19 pandemic. Despite these obstacles, CAPES's accomplishment in completing the evaluation for the 2017-2020 cycle showcases its resilience. However, the paper advocates for a more context-sensitive, holistic and impact-driven evaluation model, suggesting enhancements such as increasing the focus on self-assessment strategies. The success of proposed changes hinges on CAPES's sustained existence, bolstered by stable funding. The overarching vision is an evaluation system that not only ensures equitable results, but also cultivates a culture of continuous improvement within Brazilian graduate programs and their role to address relevant societal needs.
