School districts are sometimes different from other local jurisdictions. They have their own officials and budgets. Education standards and state tests are created by the state governments. Since child education is required by law, ages to start school are different from each state. Children usually start school between the ages of five to six. They usually end their education when they are between the ages of seventeen and eighteen. Education requirements can be done by educating children in public schools, private schools (who is known by the government to be trusted) or a home school program. In most public schools, education is divided into three levels. The first level is elementary school. Grades in elementary school are different in each state. The second level is middle school. Grades in middle school are different in each state as well. The last level is high school. In some states, middle school is called "junior high school". Grades in high school are also different in each state. After a child has completed their senior year (12th grade), they will earn a high school diploma.
