What Is 21st International Students Science Fair?
ISSF 2026 is the International Science Schools Network's 21st student science fair, hosted in person by the Australian Science and Mathematics School in South Australia from November 30 through December 4, 2026. The theme is “Experimentation Across Borders.” The host says schools from around the world will collaborate with science as the focus and has scheduled a cultural evening for December 2.
ISSF is the flagship event of a network of specialist science secondary schools. Prior editions use school delegations of students and staff and include research posters or presentations, scientific discussion, workshops and cultural exchange. No public individual application, registration fee, exact student age/grade rule or 2026 delegation-selection procedure is posted in the current official sources. Students should therefore ask their school's ISSN or international-program coordinator.
