In the second stage, the Tobit regression model was applied to assess the variables impacting efficiency. Originality / Relevance: The application of the DEA showed that it is a promising tool to support the monitoring and inspection of ANATEL, since it uses different combined criteria, not only quantitative and qualitative criteria. Main results: The results of the study pointed out that the proposed model is valid and indicated that Operator 4 growth in the efficiency indicator the three months to take. The HDI
