Gateway College was established in 1997 in a converted house with 33 students and 8 members in the tutorial staff. In January 2005, the school decided to change from Gateway International School to Gateway College signaling a new era in the history of the school and in the International School System of Education in Sri Lanka.

In 2013, a decision was made to change the school motto from ‘Gateway to Knowledge’ to ‘Gateway to Learning’. The decision that was taken after much thought, signifies our vision in educating our children as we believe that the one skill that will be required for the future, is the skill of being able to learn.

Provision of learning of the highest global standards while retaining the culture of the land was the raison d’etre for the establishment of Gateway College. Gateway proudly proclaims that it is an international school in a Sri Lankan environment. The school has taken meaningful initiatives to inculcate in the minds of children, be they Sri Lankan or of other Nationalities, a sense of belonging and love for their Motherland and respect for its customs, norms and values.

Students engage themselves in daily religious observances and a variety of religious, charitable and social service activities throughout the year. All Gateway students are exhorted to pay obeisance to their parents daily according to the customs of the community they belong to. The student teacher relationship in the school is essentially friendly and the management style is firm, friendly and fair.
