The English Schools Foundation (ESF) is an organisation that runs 22 international schools in Hong Kong. It is Hong Kong's largest English-medium organisation of international schools. It was founded in 1967 with the passage of the English Schools Foundation Ordinance, under which it is mandated to provide "without regard to race or religion, a modern liberal education through the medium of the English language". The schools have progressively improved their facilities, especially in ICT with the help of donations from Parent Teacher Associations.
