Public education systems are organized structures that provide free education to children and young adults, typically funded by government sources. These systems aim to ensure that all students have access to basic education, regardless of their background or financial situation. Public schools often follow a standardized curriculum set by local or national authorities. In many countries, public education systems include various levels, such as elementary, middle, and high schools. They may also offer specialized programs for students with different needs. Teachers in public schools are usually required to have specific qualifications and certifications to ensure quality education for all students.
