Saint Andrew's Scots School was founded in Buenos Aires by a group of Scottish immigrants looking to maintain their cultural identity while contributing to the growing society in Argentina. Founded in 1838, it emerged as the oldest school of British origin in South America. The institution was established to provide a British-style education, focusing on delivering a curriculum largely composed of British subjects, including the English language, history, and mathematics. This educational approach was particularly significant for the expatriate community, as it served to bridge the cultural gap between the new world and their homeland. The founding of the school was predicated on a desire to maintain Scottish customs and traditions among families who settled in the region. Furthermore, Saint Andrew's Scots School also points to the influence and presence of the Scottish diaspora in Argentina, which can be traced back to earlier migrations in the 19th century.

In the early years, the school catered primarily to the children of British settlers, creating an academic environment where young learners could receive an education that aligned with their heritage while also adapting to their new surroundings. The school began modestly but quickly grew in popularity, becoming central to the Scottish community in Buenos Aires. It provided not only education but also a supportive social network, hosting various cultural events that reinforced Scottish traditions and values among immigrant families.

As the years progressed, Saint Andrew's Scots School continued to adapt and evolve, reflecting changes in educational standards and approaches while maintaining its foundational principles. Today, it remains a prominent institution, recognized both for its historic significance and its ongoing commitment to providing quality education, fostering cultural appreciation, and adapting to contemporary educational demands.
