The school is split between two campuses on either side of Avenida Desierto de los Leones.

It was founded in 1963 by Edward Foulkes, a Welshman who worked in Mexico in the publishing business and as a teacher for the British Council, and by Ronald Stech, a Canadian who became the school's first administrator.

[citation needed] Foulkes, who had previously founded Greengates School, had left by 1961, selling his share to Henry Coehlo.

In 1985, it moved from San Ángel to its present site in a residential area close to the forested hills of Desierto de los Leones.

At the same time, it achieved its bicultural status through incorporation with the Mexican education authority.
