This paper aims to analyze, under the theoretical possibilities of the indiciary paradigm, the methodology used in the construction of the Ideb algorithm and of intermediate goals for the quality of Brazilian Education, looking for evidence that will lead us to understand the concept of quality of Education assumed by the indicator. It is a qualitative study, which uses researching bibliographies and analyzing documents as a theoretical-methodological approach considering, as sources, the official technical notes made available to describe the statistical-mathematical procedures utilized in the design of the indicator. Results showed the mathematical rigor and the care taken by MEC/Inep professionals to differentiate the biennial goals projected for each teaching modality and in all administrative spheres. On the other hand, they expose some weaknesses at not considering the specificities surrounding the Brazilian educational reality, compromising the reliability of the evidenced results.
