What teachers and parents say

Positives

  • Close-knit community: Warm, inclusive 'village' atmosphere where staff, students, and families know each other personally.
  • Small class sizes: Allows for tailored individual student support and gives teachers autonomy with little micromanagement.
  • Established IB continuum: Experienced delivery of all three IB programmes within a diverse, non-corporate setting.

Negatives

  • Aging campus and limited facilities: Infrastructure is dated and lacks the extensive modern amenities and sports grounds seen at Singapore's mega-campuses.
  • Lower compensation and tighter resources: Pay scales and institutional budgets lag behind top-tier international schools in Singapore.
