What the school says

"One World International School offers an excellent international education to children from the ages of three to 18 in a nurturing multicultural environment at an equitable fee point. We have a diverse student and teacher community with more than 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 optimal class sizes for the different key stages, 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 connections 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.

"We offer three vibrant learning environments for parents to choose from – the first is our established, all-through campus in Nanyang (Jurong West); the second is our engaging campus for Early Childhood and Primary School at Suntec in the Downtown Core area; and the third is our upcoming ultra-modern Digital Campus* in Punggol that will open in August 2023."

*Proposed site for an international school set to open in August 2023 subject to regulatory approval.

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!”
