Why Bloom

New by design.
Clear in purpose.

A serious international education, in a school small enough to know every child.

A purpose-built campus and intentionally small cohorts. As a new school, we have shaped our learning environment around the needs of our students, rather than being limited by traditional ways of doing things.

01Known by name
Small cohorts and individual attention — no child disappears into the crowd.
02Multilingual by design
English, Khmer, Chinese, French and Spanish, woven in from Early Childhood.
03Inquiry-based learning
Children learn by asking, testing and building.
04A genuine school community
Families, teachers and students who actually know one another.

How children learn at Bloom

Learning through inquiry

At Bloom, learning starts with a child's own questions. They investigate, test ideas and connect what they discover across subjects — so knowledge is something they build, not just receive.

Bloom is an IB Candidate School* for the Primary Years Programme (PYP) — the IB's framework for learners aged 3–12 — and the approach behind our Early Childhood and Primary classrooms.

Inquiry-based — lessons begin with wonder and a real question.
Transdisciplinary — six global themes link every subject together.
The learner profile — ten attributes, from caring and open-minded to reflective.
