Message from Mrs. Ranmalee
“Every child carries a pledge of a brighter tomorrow. Every parent dreams of a gleaming future for their offspring. At Colombo South International College, our purpose is to kindle that pledge through knowledge, character, and opportunity to make those dreams come true.”
We believe that greatness is not measured solely by academic achievement, but by the values we uphold, the lives we touch, and the positive difference we make. Together, we inspire young minds to dream boldly, think wisely, and lead with integrity.
I invite you to become part of a learning community where excellence is a tradition, innovation is embraced, and every child is empowered to flourish.

“At Colombo South International College, our IGCSE Section is dedicated to nurturing confident, responsible, and independent learners who are prepared to succeed in a rapidly changing world.”
With 16 years of experience in education, I strongly believe that true learning extends beyond examinations; it should develop critical thinking, resilience, creativity, and strong moral values.
Through the collective commitment of students, teachers, and parents, we aim to create an ambitious yet supportive learning environment in which every student is encouraged to recognize their potential, embrace challenges, and work purposefully towards a successful and meaningful future.

Message from Mr. Oshadha
“It is an honour and a privilege to serve as the Vice Principal of the National Section at Colombo South International College. I firmly believe that education extends beyond academic achievement—it is about nurturing integrity, leadership, innovation, and a lifelong passion for learning.”
With over 14 years of experience in education, I have dedicated my career to empowering young minds through academic excellence, disciplined learning, and character development. My commitment to academic advancement has also led me to engage in scientific research, with my work selected for presentation at an international research conference.
Throughout my professional journey, I have served in several leadership capacities, including Master-in-Charge of the Board of Prefects, the Buddhist Society, and the Media Unit. These experiences have strengthened my belief that every student possesses the potential to become an inspiring leader when provided with the right guidance and opportunities.
At CSIC, I remain committed to creating a safe, inclusive, and inspiring learning environment where every student is encouraged to achieve academic excellence while developing the values, confidence, and resilience needed to succeed in an ever-changing world.

“The intermediate period is the most crucial bridge between childhood and adolescence. It is during Grades 6, 7 and 8 that a child builds confidence, character and clarity for the future.”
As a graduate with extensive experience in both teaching and administration, and with the support of our qualified and experienced teachers, I have had the privilege of guiding young learners through this important journey. Our commitment has always been to ensure that every child feels seen, heard, and supported to achieve their best.
In our section, we do not just focus on academic excellence, but on nurturing discipline, values, and resilience. We provide a safe, structured, and inspiring environment where your child is encouraged to explore, to question, and to grow.
We understand that choosing the right school is choosing a second home for your child. We assure you that here, your child will be in caring and capable hands.
I warmly welcome you to join our school family and be a part of your child’s beautiful transformation.

Science is truth discovered through questions and experiments. It teaches logical reasoning, data analysis, and evidence-based conclusions, preparing the younger generation to solve global challenges while promoting resilience through hands-on discovery.
We prepare students to find solutions to real-life problems through classroom lessons, research projects, and outdoor surveys. The majority of our staff hold postgraduate degrees and bring extensive experience at both national and international levels. Our department has consistently produced outstanding results in Edexcel IGCSE and International Advanced Level examinations, including world-best and country-best achievements.
