Global Indian International School Singapore

The flagship of the Global Schools Foundation network and the original Indian-curriculum option in Singapore, with a large multi-campus footprint and a flagship SMART Campus in the Punggol Digital District.

GIIS opened in 2002 and now runs four Singapore campuses, with the seven-storey SMART Campus in Punggol the headline site. Curriculum is layered. Families pick between CBSE, IGCSE and the IB Diploma, with Montessori and an early years stream below. The 2025 IBDP cohort averaged 37.2, well above the global average. The school is Singapore's main alternative to NPS for families staying close to the Indian system.

The pull for Indian expat families is curriculum continuity, cultural familiarity and fees that sit well below the headline British and American schools. Reviews praise communication, the bridge programme for new joiners and the breadth of co-curricular labs. The honest read is that GIIS is a large, formal, exam-focused environment. Families wanting the smaller pastoral feel of a Tanglin or UWC class will not find it here.

• GIIS Singapore is one of the most discussed Indian-curriculum schools in the country, with split commentary across Reddit, community discussions and directories.
• A recent thread features a parent saying they decided against enrolling, citing what they called "backward" management style, alongside another former student replying that they did not encounter the same issues during their time at the school.
• Reddit's other recurring line is fee competitiveness: parents and students repeatedly call out that GIIS sits well below most international schools in Singapore, helped by frozen fees on the Punggol SMART Campus.
• Directory reviews are largely positive on academics, with WhichSchoolAdvisor noting strong IBDP top scores and IGCSE A* outputs across years, plus a long catalogue of facilities at the SMART Campus.
• Sentiment splits by campus: East Coast carries a average from a small pool, while the SMART (Punggol) campus sits at middling with parents praising sports provision, teacher availability and university outcomes.
• Some parent comment questions whether the school is too "Indian" in feel for non-Indian families and whether the IBDP scholarship pipeline drives a high-pressure academic culture.
