The National Common Curricular Base for Early Childhood Education (BNCC) is an essential document that guides the educational process in Brazil, providing guidelines for curriculum organization in the initial stage of education. In this article, we discuss the signifi cance of the BNCC in structuring the curriculum in Early Childhood Education, highlighting its methodology of implementation and the expected outcomes for the holistic development of children. To achieve this, we employed a methodology of documentary studies, analysis of educational legislation, and a review of related research literature. Through data collection and synthesis, we aimed to emphasize the principles and objectives of the BNCC, its pedagogical guidelines, and its contribution to curriculum structuring in this educational stage. As a result, we identifi ed that the BNCC aims to promote the holistic development of children, encompassing cognitive, socio-emotional, physical, and cultural aspects. By proposing a curriculum based on these guidelines, we seek to ensure that all children have meaningful and age-appropriate learning opportunities according to their developmental stage. The curriculum becomes more fl exible and contextualized, recognizing the importance of considering each school’s particularities and valuing cultural and regional diversity. Furthermore, the BNCC guarantees rights and equity, as it establishes learning rights for all children in early childhood education, regardless of their origin, social status, or specifi c needs. Organizing the curriculum based on these rights aims to promote educational equity and combat inequalities. The BNCC also highlights the signifi cance of play as a pedagogical principle, recognizing it as a form of expression, learning, and child development. By organizing the curriculum based on this principle, the role of play in the educational process is valued, providing playful and creative moments for children.
