A key event on the Dover Court calendar is its annual United Nations Day - a celebration of the school's rich cultural diversity among students and staff. In its early years, United Nations Day was conducted in cooperation with Dover Court's then sister school, Singapore Preparatory School, Katong - also owned by International Schools (Pte) Ltd. While the day has taken on many forms over its almost half-a-century history, a constant fixture of the event is the 'Parade of Nations', in which students parade in front of parents, wearing their cultural dress. It was noted in an article about the 1984 Dover Court United Nations Day by the acting representative from the United Nations High Commission in Singapore that the students "represented the true spirit of the UN".
