Typical ages and grade groupings in contemporary, public and private schools may be found through the U.S. Department of Education. Generally there are three stages: elementary school (K-5th/6th grade), middle school (6th/7th-8th grades) and high school (9thâ12th grades).
Elementary school is a school for students in their first school years, where they get primary education before they enter secondary education. The exact ages vary by country. In the United States, elementary schools usually have 6 grades with pupils aged between 6 and 12, but the age ranges 6 to 10 and 6 to 14 also exist.
