The OzCLO contest is held in two rounds.
The First Round is a two-hour competition, usually held in early March. Participants work in teams of four on a range of language-analysis problems. The teams are usually selected by their schools. The competition is held at the school with teams submitting their answers through an online quiz. Some regions offer offline alternatives.
The National Round is by invitation to the top three teams for each region. This has the same format as the First Round but is held at a local host university. The National Round is usually held in late March.
The winners of the National Round are offered the opportunity of representing Australia at the International Linguistics Olympiad (IOL), which is usually held in late July or early August.
All participants complete the same tasks, with achievements recognised at the Junior level (years 9-10) and the Senior level (years 11-12).

Training sessions for participants are also sometimes held in-person at various locations. We explain how the competition is run and give an overview of the fields of linguistics, computational linguistics and language technologies. We also go over sample problems and give tips for solving them. If you would like to find out more about training sessions in each state, please email the local organisers.
