ISDA Debating

Independent Schools Debating Association


The Independent Schools' Debating Association (ISDA) is the premier student debating competition for independent schools in Sydney.


Debating encourages and challenges young people to engage critically and constructively with each other to explore the most controversial, pressing and age-old questions facing our society.


The ISDA brings schools, students, teachers, supporters, coaches and adjudicators together for seven hotly contested rounds of debating on Friday evenings.
