Elementary school is a school for students at their first school years, before they enter secondary education.

The exact ages vary by country.

Elementary school is usually part of the compulsory education, especially in the Western countries.

A middle school (also known as intermediate school or junior high school) is an educational stage, which exists in some countries, and takes place between primary school and high school.

The concept, regulation and classification of middle schools, as well as the ages covered, vary between, and sometimes within, countries.

K–12 (spoken as "k twelve", "k through twelve", or "k to twelve") comprises the sum of primary and secondary education in the United States, Canada, South Korea, Turkey, Philippines, Egypt, Australia, India, Afghanistan and Iran for publicly-supported school grades prior to college.

The expression is a shortening of kindergarten (K) for 4- to 6-year-olds through twelfth grade (12) for 17- to 19-year-olds, the first and last grades of free education in these countries, respectively.

The related term P–12 is also occasionally used in Australia and the United States, to refer to the sum of K–12 plus preschool education.

In most jurisdictions, secondary education in the United States refers to the last four years of statutory formal education (grade nine through grade twelve) either at high school or split between a final year of 'junior high school' and three in high school.
