American schools are educational institutions that provide instruction to students from kindergarten through 12th grade. They are typically divided into three main levels: elementary, middle, and high school. The curriculum often includes subjects such as math, science, language arts, and social studies, with additional courses in art and physical education. Public schools in the United States are funded by local, state, and federal government sources, while private schools rely on tuition and donations. Education is compulsory in most states, meaning children must attend school until a certain age. Schools often emphasize the importance of critical thinking and social skills to prepare students for future challenges.
