The public school system is a network of educational institutions funded and operated by government entities. It provides free education to children, typically from kindergarten through 12th grade. Public schools are designed to serve all students in a community, ensuring access to education regardless of a family's financial situation. In the United States, the public school system is managed at the local, state, and federal levels, with each state having its own regulations and standards. Public schools often follow a standardized curriculum, which includes subjects like math, science, language arts, and social studies, aiming to prepare students for higher education and future careers.
