In 1975, Lady Anne Henderson-Stewart founded Le Jardin d'Enfants Bilingue and in 1983 La Petite Ecole Française in London for children of all nationalities. This London school, approved by the Ministry of Education, is fully integrated into the French educational system. In 1999, Sir David Henderson-Stewart, owner of the Little French School in London was awarded the title of Knight in the Order of Academic Palms for his contribution to the dissemination of French culture in Britain.
Based on her experience in London, Lady Anne Henderson-Stewart opened La Petite Ecole Bilingue in Paris on 1995. This school is renowned for the quality of its teaching, offering students a solid foundation and equipping them educationally and socially for their future.
In 2007, Lady Anne Stewart Henderson decided to hand over La Petite Ecole Française, to devote herself to a bilingual school project, at the request of many parents. Thus, in 2010 she opened La Petite Ecole Bilingue in London at Oxford Gardens. This school welcomes pupils from the age of 2. Furthermore, to meet the growing demand from parents another new school La Petite Ecole Bilingue in Kentish Town was opened in September 2012.
Today La Petite Ecole Bilingue-Stewart International School comprises a total of 4 schools based in London and in Paris. Lady Anne Henderson Stewart oversees these schools and ensures that they are consistent with each other in their pedagogical approach.
