This work seeks to understand the implementation of public policies as a complex process involving diverse actors and decision-making. In this research we study the performance of the State and District Public Defender Offices, through the defenders who work in the Justice System, of legal assistance to adolescents in conflict with the law of the socio-educational policy, in a context of the COVID-19 pandemic in Brazil. The research was conducted in three stages through various methodological strategies. First, a documentary analysis of already available data was conducted, based on CNJ Recommendation N. 62/2020, the SINASE Evaluation Survey (2020) and the National Survey of the Public Defender's Office (2022). In the second part, the questionnaire was applied through an online survey in a single step, with a convenience sample, with 34 voluntary responses. In the third stage of the research, 6 interviews were conducted with Coordinators of the Public Defender's Offices linked to the area of Children and Youth, following a semi-structured script. Finally, a content analysis of the data produced and a triangulation of all the information was carried out. The general objective was to understand the role of the State and District Public Defenders in the implementation of the socio-educational policy in the context of the pandemic. From there, it was listed two specific objectives: a) Analyze to what extent this performance of the Public Defenders contributed to the guarantee or maintenance of violations of fundamental rights of adolescents in conflict with the law in this period of the Covid-19 pandemic; and b) Understand what factors influence the exercise of discretion of the State and District Public Defenders in the implementation of the Socio-Educational Policy. The dissertation aims to contribute to the studies on the implementation of public policies, especially in the scope of the Street Level Bureaucracy, in a context in which the State's presence has never been so demanded in the fight against the coronavirus and in the care of the Brazilian population.
