"Estadual" refers to something that is related to a state, particularly in the context of government or administration. In Brazil, for example, each of the 26 states has its own government, laws, and regulations that operate independently from the federal government. This allows states to address local issues and needs more effectively. In the context of education, "estadual" can describe public schools that are managed by state governments. These schools are funded and regulated by the state, providing education to students within that specific region. This system ensures that educational standards can be tailored to the unique demographics and requirements of each state.
