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).
Different authorities introduced different age-range schools, although in the main, three models were used: 1  4â6 First schools, followed by 7â11 middle schools, as suggested by Plowden. 2  5â9 First schools, followed by 9â13 middle schools. 3  5â10 First schools followed by 10â13 middle schools, or intermediate schools.
