The present study aims to analyze the implantation and implementation of the Experimental Program of Full-time Education of Corumbá in Mato Grosso do Sul, between the years 2009 and 2015 that aimed at extending the school day with a new curricular organization in three urban schools and a rural one. To understand this process, we adopted the qualitative methodology with analyzes of bibliographic, documentary and oral sources. We have taken a historical approach to full-time education to understand politics at the local level. For that, we presented the different philosophical, ideological and political matrices about the concept of full-time education that emerged in Brazil at the beginning of the 20th century, and the main full-time experiences practiced by the country. We analyzed the legislation and the current discussions on the theme and the main theoretical references on the subject. To understand the local experience, we analyzed the documents and texts that dealt with the full-time education policy of the city. We also conducted semi-structured interviews with directors, coordinators and teachers. Three models guided directly the program of Corumbá: the More Education Program, the Carioca Gymnasium and the School of the Ponte. We conclude that schools had difficulties in understanding and putting into practice what was prescribed, on the other hand they sought, each in their own way, to increase daily time and school activities. Therefore, it was set up in a proposal for full-time integral education in construction. And due to its configuration, it was marked by the low investment by the government and location of the schools, it runs the risk of not being expanded to other education network units.
