International Journal of Engineering Research and Science is indexed by Qualis CAPES Brazil.
Qualis is a Brazilian official system with the purpose of classifying scientific production. It is maintained by the Coordenadoria de Aperfeiçoamento de Pessoal de Nível Superior (CAPES), a government agency linked to the Brazilian Ministry of Education.
Qualis has the task to classify and evaluate the academic means used on the production of scientific publications of post-graduate programs (such as master theses and doctoral dissertations). The classification itself occurs by a system of grades, per field of evaluation, and depends on the level of circulation (local, national or international) and on the quality of the journal (A, B, or C).
