This paper presents how the Legislative Schools in the South of Minas region are structured, to understand their characteristics and resources spent on the work, since there are forty of them instituted in the region, of which twenty-six are active. Thus, structural aspects are considered, human resources, budget, planning and control tools, political-pedagogical plan, scientific production, and publications, as well as the use of electronic sites and social networks. This quantitative-qualitative study was carried out between March and May 2021, through the application of questionnaires and interviews with four leaders of Legislative Schools in the South of Minas region. The results are divided into eight topics and indicate how structures are preponderant for the work developed by these schools but demonstrate that the Legislative Schools can evolve their work by improving their structures.
