Anglo-Argentines have traditionally differed from their fellow Argentines by largely retaining strong ties with their mother country, including education and commerce. There are many schools in Argentina that are bilingual, offering a British curriculum in English and the standard Argentine curriculum in Spanish, including Northlands School, St. Mark's College, Balmoral College, St. Alban's College, St. George's College, Belgrano Day School and Washington School. Buenos Aires had a number of branches of the Asociación Argentina de Cultura Inglesa (English Cultural Association), and throughout the 20th century English language learning and teaching in state schools and private institutions was invariably geared towards the Received Pronunciation. Many private boys' schools have a uniform of blue blazers and grey flannel trousers.
