The School

Every child has the opportunity to receive a truly world class education in a disciplined, spiritual and morally uplifting school environment upholding Sri Lankan values and the diversity of our culture. This makes Gateway College a unique learning experience.


Founded by Mr. R. I. T. Alles, a renowned Educationist, with over five decades of service in education, both in the public and private sectors, the organisation has progressed at great speed guided by sound principles, values, and love.

Being a teacher of Royal College, Colombo, then, the Founder Principal of D.S.Senanayake College, Colombo, and finally the State Secretary of Education overlooking all schools in the island, late Mr. Alles brought in a wealth of experience to this establishment. Further, his initial training in Cambridge and the subsequent exposure by way of a scholarship awarded by the International Development Research Centre in Ottawa to study school systems in more than ten developed countries helped him to lay the foundation to a truly international organisation.

Message by Mr. R.I.T.Alles issued in 2007

"Parents are children's first and most lasting carers. Every parent aspires for his children to be worthy citizens. Children have a remarkable ability to learn. They want to learn to fulfil their dreams. Be it the aspirations of parents or the dreams of children, they all seek a "Gateway" to reach their goals. We strive to be that "Gateway" to our parents and children.

The four stakeholders in a school are the teachers, parents, the students and the Alumni. It is my wish and vision that these four categories will always have a sense of belonging to each other. For this, one category to the other, they should work hand in hand, always upholding a pervading sense of love and understanding."

Message by Mrs. Rohini Alles

"In a co-educational institution with a religious and cultural mix, one would expect to have many challenges. To us, these challenges are small because we confront them and not evade them. I am a believer that the word 'impossible', is often just an excuse we make for ourselves. Real service cannot be bought or measured with money. Let's remember these thoughts in making Gateway the beacon light for our children."
