About One World International School
One World International School is more than just a learning institution. While educating the next generation of leaders is our top priority, we want our students and families to know that we are a welcoming, diverse and inclusive community that strives to help all of its members make meaningful connections with one another. We have a team of world-class staff members who are passionate about education, and we are proud of the families who make up our student community. Our approach to education is distinctly different from many of the other schools in Singapore. Kindness is integral to everything we do at OWIS.
Learning & language support (SEN / EAL)
This school states meaningful learning-support provision — still confirm it fits your child's specific need.
Why this matters
Special-needs provision at international schools varies widely and is rarely guaranteed by the school itself — and local legal duties differ by country. Confirm what this school provides, in writing, before you commit.

Questions to ask the school

- Can you support a child with my child's specific need (e.g. dyslexia, ADHD, autism), and have you done so this year? Ask for concrete examples.
- Is there an additional fee for learning support or EAL — and how much per year?
- Is learning support guaranteed for the full enrolment, or can it be withdrawn later?
