Start Your Child’s English Success Story With OWIS

Proud Member of the Global Schools Group (GSG)

The Global Schools Group is a chain of K-12 schools headquartered in Singapore. The organization was founded in 2002 with the goal of providing affordable, high-quality education to international communities worldwide. Nearly two decades later, the group’s schools have received more than 650 national and international awards for academic excellence.

We can help your child by:

Offering them a learning environment where they are supported by dedicated and expert educators who are thoughtful and experienced.

Encouraging them to challenge themselves and continue to work toward their goals by providing them with a best in class curriculum.

Allowing them to explore their interests through a variety of extracurricular programmes.

Teaching them to socialize with their peers and allowing them to learn to be respectful and empathetic of people of all backgrounds.

OWIS's Educational Model

Rather than follow a rigid framework, our approach fosters concept development across subject areas to make the learning relevant and meaningful beyond the classroom.


Here are the core principles behind our one-of-a-kind framework.

One with the World

Our motto. Our international school model ensures a well-rounded education, with an emphasis on multiculturalism, that prepares students to be and lifelong learners.

Learning

We offer internationally recognized curricula that support our students ambitions in higher education and the workplace, whilst cultivating natural curiosity and encouraging them to take ownership of their learning by incorporating their interests into the lessons.

Collaboration

Group learning prepares children to work with people from different backgrounds. Collaboration not only instils a sense of responsibility, it also promotes social skills, creativity and higher order thinking. Students learn to appreciate perspectives that differ from their own.

Service

We encourage students to become aware of the needs around them and to respond with empathy and action. Through meaningful contributions to charitable initiatives, the school community, and the local neighbourhood, students connect with others in ways that extend far beyond the traditional classroom.

Relationships

Our school model emphasizes the qualities that support healthy connections, such as clear communication, empathy, and kindness. We help students reflect on their relationships with family, teachers, peers, and the wider community.

Values

We emphasise resilience, open-mindedness, humility, and healthy self-esteem — qualities essential for thriving in a global society. When students develop a strong sense of self-worth, they are better able to value others, set meaningful goals, and contribute positively to the world around them.
