El Colegio Británico (Edron) is a non-profit making institution 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.

Their vision was to create a learning community in which every child would feel secure, wanted, cared for and free from tension and hostility.

The school has retained these values, while in other respects it has experienced dramatic changes. In 1985, it moved from San Angel to its present beautiful site close to the forested hills of 'Desierto de los Leones' and high above the worst effects of Mexico city's pollution At the same time, it became bi-cultural.

With these developments , the school came to serve mainly a Mexican population whose interests in the school were due mainly to family or work links with Britain or the USA .This gives the school a very desirable combination of stability and internationalism in outlook.

At present, the enrolment is over 850, the highest in its history. In comparison with other schools , the class numbers remain small and the staff/student ratio is high.
