The purpose of this article is to describe, from the comparative perspective, the structure of the education systems belonging to Latin America and the Caribbean Region countries about the early childhood segment. The analysis of various international reports and official documents on the progress of the programs in terms of coverage, investment, regulations, among others, was carried out. The documentary nature of this work allows a comparative approximation among the countries about the way in which it deals with early childhood schooling in each country of the region. One of the most outstanding achievements is that linked to the expansion of the first level of education and the coverage achieved. Increasingly, societies are aware of the essential role of early childhood education in the well-being of children and how it influences their cognitive and socio-emotional development. Although considerable disparities are reflected between one country and another, but the universalization of the level plays as a determining factor to deal with social inequalities and promote better overall student outcomes. On the other hand, the countries that make the greatest investments are those that have the greatest social development.
