The social sciences are very present in daily life, since knowledge such as geography, history, sociology, etc., has an impact on people's daily lives. In the educational stage of Early Childhood Education, the teaching of historical content is developed through projects that allow students to discover and investigate a certain historical stage. But do these contents related to social sciences really appear in the Early Childhood Education curriculum? This work aims to know how social science content is included in the curriculum of this stage. To this end, the legislation that regulates Early Childhood Education in Extremadura has been analyzed to establish comparisons in the treatment of social sciences within it. The methodology used has been qualitative, and more specifically, a documentary data analysis has been carried out where the last two Early Childhood Education decrees of Extremadura have been analyzed: Decree 4/2008 and Decree 98/2022. The results obtained suggest that in Decree 98/2022 there is more presence of social sciences than in the old Decree 4/2008, although this presence in both decrees is very generic and refers more to processes related to socialization.
