Founded by eight Heads in 1916, igsa has become an active and vibrant community of over 32 schools – encompassing approximately 25,000 girls. Continuing the tradition of creating opportunity and growth for girls, igsa has oversight of various interschool activities including igsa Sport, Tildesley Tennis, igsa Festival of Speech, igsa Choral Festival and igsa Archdale Debating.
Supported by educational research, it is our belief that single-sex schools are intentionally equipped with the knowledge and skills to provide the best opportunities and outcomes for girls.
