January 1956 saw a significant era in the history of St. Andrew's School; her institution.

Canon Paul Chong En Siong always had in mind that for the church to nurture her young was through the teaching in Christian schools. Even though it was no easy task, with the help of parishioners, friends and family, he was able to establish the first Anglican school in Brunei town.

St. Andrew's started from humble beginnings; with only 70 students, 3 teachers and a minute area of learning. Due to lack of resources, the school could only cater for the lower learning classes-the highest being Primary Four.

Though St. Andrew's School had begun in a very small way, there were difficulties to be faced-difficulties such as in having to cope with the great differences in age in a class, the poor facilities, and difficulties on the administrative side. These were overcome and by the end of 1957, the school still existed. In 1964, the school moved from the church vicarage to its present site, benevolently donated by Dato Ong Kim Kee. Thus from this very small beginning, this mustard seed, St. Andrew's School has grown into what it is today. It is Canon Paul's wish that the school "continue to grow and prosper".

At present, St. Andrew's has fully grown to a fully equipped institution of learning which can accommodate up to 1700 students.

St. Andrew's School has not wasted time or opportunities in its service and position in public education. In 1995, Computer Studies was introduced to our Secondary One students. In 2000, a Mandarin Club was formed to cater those who wants to learn the language. At the same time, sports, games and other Extra Curricular Activities are also encouraged and expanded. The school will continue its role in the country with a commitment to excellence in education for the school children in Negara Brunei Darussalam.
