Secondary education in the United States
Types of schools
The United States public education system is structured into three levels: elementary (also known as primary) education, middle and high school (which is secondary together) education, and college or university level (also known as post-secondary) education. Schooling starts at age 5-6 and ends anywhere from 16-18 depending on the school system, state policy, and the students progress. Pre-School or Pre-Kindergarten accept as young as age 3 and is not required. From there education models differ as elementary school can last anywhere from grade 5 (age 10–11) to grade 8 (age 13–14) depending on the structure. Some states have middle schools which is part of secondary education and between elementary school and high school encompassing grades from 6 to 9, while others have no middle school and instead combined mixed high schools. High school is generally grades 9-12, with the exception of the mixed model which is 7-12.
