The K-12 education system refers to the public and private schooling that children receive from kindergarten through 12th grade. This system is designed to provide a comprehensive education, covering basic subjects such as math, science, language arts, and social studies. It typically serves students from ages 5 to 18, preparing them for higher education or the workforce. In many countries, the K-12 system is divided into three levels: elementary school (grades K-5), middle school (grades 6-8), and high school (grades 9-12). Each level builds on the previous one, ensuring that students develop essential skills and knowledge as they progress through their education.
