摘要：The study verifies the level of efficiency of state public schools in Goiás, through the performance of national high school exam (ENEM) and the average cost per student. In a second stage, the conditions of efficiency are determined. For the evaluation of efficiency the Data Envelopment Analysis (DEA), a nonparametric method, is used and at second stage, the inflated beta regression is used, which accommodates the interval of results from the first step. The empirical evidence shows that military and more specialized schools tend to outperform others, while the schools with a full-time teaching and higher average class time, tend to be inefficient.
