About ISQ

Queensland independent schools, sometimes referred colloquially in the community as private schools, are not-for-profit education institutions that are as diverse as the students they educate and the communities they serve.

Independent Schools Queensland (ISQ) is a not-for-profit peak body, dedicated to championing independent schools across the state. 

We are committed to: 

  • enhancing school-wide performance, robust governance and improved student outcomes 
  • promoting excellence and leading research in education-related public policy 
  • delivering quality professional learning  
  • fostering collaboration and continual growth across the sector
  • being a united and powerful voice for Queensland independent schooling. 

ISQ is governed by a Board of Directors and day-to-day operations are managed by Executive Director, David Robertson, an Executive team and more than 60 staff based in its Brisbane (Spring Hill) office.

ISQ's Board of Directors is chaired by Karen Spiller OAM CF. The Board has various associated committees.
