Archdale debating competition The Archdale Debating Competition is a competition conducted by the Association of Heads of Independent Girls' Schools for the benefit of students from 24 of its members' schools. Established in the early 1970s, it is an annual competition conducted over two terms (typically between March and August), with each member school entering a team into each of the divisions. The Archdale Shield is awarded to the school which performs best across the whole competition. The award is determined through an overall points score after the conclusion of the final round. The competition is named in honour of Helen Elizabeth (Betty) Archdale (August 21, 1907–January 11, 2000), former principal of The Women's College at the University of Sydney (1946–1957), and former headmistress of Abbotsleigh (1958–1970). Betty Archdale was also a talented cricketer, captaining the English women's cricket team in 1934 and 1935. In 1944 Archdale was awarded an Order of the British Empire for her part in getting nurses out of Singapore during World War II. In 1999 she was one of the first ten women to be granted Honorary Life Membership of Marylebone Cricket Club in England. Archdale was listed as an Australian Living Treasure in 1997. History Although a number of AHIGS schools offered debating as an extracurricular activity from around the 1920s, it was not until the 1960s that inter-school debating became common among girls' schools. In 1971, following a debate between Abbotsleigh and a combined high schools team, the decision was made to form a debating organisation for independent girls' schools. This organisation was called 'ISSGDA', and it was made up of sixteen independent schools (girls' and co-educational) divided into four geographic areas for competition purposes. The first ISSGDA final was contested between Abbotsleigh and Moriah College (the only non-AHIGS school to compete) at Abbotsleigh. The trophy, which Miss Archdale had donated, was won by Abbotsleigh and presented by Miss Kathleen McCredie, the then headmistress of Abbotsleigh. From this point on, the competition became known as the 'Archdale Debating Competition'. Archdale winners Festival of Speech The concept of a 'Festival of Speech' for the Association of Heads of
