School Structure
Administrative Structure

At OSC, we believe in the development of the whole person in an environment that emphasises excellence and achievement, actively embraces cultural diversity and acknowledges and accommodates the needs of the students.
Integral to our philosophy is the recognition that students learn differently and that individual needs are best served by a broad and balanced curriculum, delivered using a wide range of instructional techniques. This is enhanced by a strong emphasis on co-curricular activities and community service.
The relationship between student, parent, and teacher is critical in serving the learning needs of our students. Schools are no longer islands where classroom doors are closed. Rather, parents are our partners. At OSC, we value and cherish parental involvement in all stages of the learning process.
We believe that our students should be equipped with the skills and competencies necessary for success in life. They should be independent thinkers, problem solvers, decision-makers and active participants in society and yet at the same time, exhibit international mindedness, concern for the environment and demonstrate responsibility.
