Preparing adolescents for adult life through integrated academic studies and real work

Program Overview

Maria Montessori treated the years from 12 to 18 as one stage of development and called her plan for it Erdkinder, German for “children of the earth.” The idea was a school where teenagers run real enterprises, often linked to a farm or land, alongside their academic studies.

Schools organize this stage in different ways. AMI standards list 12 to 15, 15 to 18 or 12 to 18 as the preferred age groupings (AMI/USA standards), and AMS offers separate teacher credentials for Secondary I (ages 12 to 15) and Secondary I-II (ages 12 to 18) (AMS).

Good to Know. A school that serves only ages 12 to 15 may simply call it a middle school.

Programs for ages 15 to 18 are covered on our high school program page.
