K-12 education refers to the formal schooling system that spans from kindergarten through 12th grade. It is designed to provide students with a comprehensive education, covering essential subjects such as math, science, language arts, and social studies. This system typically serves children from ages 5 to 18, preparing them for higher education or the workforce. In many countries, K-12 education is divided into three levels: elementary school, middle school, and high school. Each level builds on the previous one, helping students develop critical thinking and problem-solving skills. K-12 education is often funded by local, state, and federal governments, ensuring access for all children.
