What teachers and parents say

Positives

  • Outstanding academic track record, consistently regarded as one of South Australia's top-performing public secondary schools for SACE and IB results.
  • Strong accelerated programs, particularly the selective-entry IGNITE program and International Baccalaureate (IB) Diploma pathway.
  • Approachable support staff, with parents and former staff noting dedicated counseling teams and accessible year-level coordinators.

Negatives

  • High-stress, hyper-competitive culture, with feedback highlighting intense academic pressure and term-based GPA rankings that can lead to student and staff burnout.
  • Overcrowding and impersonal feel, where students who are not in IGNITE or top academic streams risk feeling lost in a very large student population.
