What the school says

"One World International School offers an excellent international education to children from the ages of 3 to 18 in a nurturing multicultural environment at an equitable fee point. We have a diverse student and teacher community with over 70 nationalities represented on campus, which promotes an understanding of different perspectives, cultures and global awareness.

"Our ethos is to deliver a highly personalised education for all students. With a maximum of 18 students per class in our Early Childhood programme, to a maximum of 24 in each of our Primary and Secondary classes, our teachers have more one-to-one time with each student to provide feedback and improve learning. We believe in fostering creativity and a desire for meaningful connection so that children can flourish into happy and productive adults. One World International School is a special place where every member of our community is valued and respected.

"This community is at the heart of everything we do: our cultural festivities, our celebrations, our house system and especially in all our classrooms. We understand that one of the most important aspects of learning is the relationship between the teacher and each individual student."

From the head of school

"With a 1,500-strong student community, One World International School is clearly the school of choice for hundreds of expat families in Singapore. We are an IB World School, offering the IB Primary Years Programme for younger students and the IB Diploma Programme at the pre-university level in Grades 11 and 12. We bridge these two curricula with the Cambridge IGCSE curriculum in Grades 6 to 10. This academic pathway offering globally-recognised qualifications is highly sought after for being academically rigorous, for nurturing the spirit of inquiry and critical thinking, and for being future-focused and relevant.

"Along with this commitment to a high-quality learning experience, we have kept our promise of a moderate fee structure. Students at OWIS campuses have access to everything they need for an excellent education – spacious classrooms, technology aids, premium facilities, and IB-trained, experienced and passionate teachers.

"The 70+ nationalities we welcome at our school campuses are proof that we are a truly international school. We have built our reputation for being a school that gives importance to human values, such as kindness, empathy, international mindedness and respect for diversity, and we nurture these traits in our student body.

"Our campuses and classrooms are always buzzing with energy and excitement. We are immensely proud that our students feel a sense of belonging here every day when they walk in, and that in this positive learning environment, we are laying the foundation for their future success.”

– Mr Mark Renie, Head of School, OWIS

What the parents say

“We moved our two kids to One World International School after much research on international schools in the locality. We were looking for a school with both a nurturing and creative environment and eventually settled on OWIS. It has not failed to deliver on any of our expectations. 

"There are many things I love about the school but these for me are the highlights: 

  1. OWIS is built on the foundation of kindness which as a parent, I was really drawn to and which they encompass into everything they do from play to the actual curriculum
  2. The IB curriculum has a good balance of innovation, practical work and encourages a growth mindset
  3. The teachers deliver classes that are fun and engaging and inspire a curious mind
  4. There is a great range of CCAs to choose from
  5. My kids love school and what more could I ask for!”

– Christina O'Hagan
