Bermuda Institute dates its history from the fall of 1943 when 17 pupils ranging from grades one to four occupied one classroom in the basement of the building then known as the Bay View Apartments.

In 1953 the school was transferred to its present site and its 129 pupils relocated in a remodelled two-storey building, on the purchased Sandringham property. As the available classroom space proved inadequate, other classrooms had to be added which included the new modern elementary building which was opened in 1961. Careful study to the upgrading of the school to a Junior Academy was given by the Mission and at the Biennial Session of 1965, it was voted that a new wing be erected. The additional building has made it possible for the program of the school to be expanded to include work equivalent to that of the average Bermuda High School. This means that Bermuda Institute, by action of the Mission Biennial Session held May 1967, is now among the nearly 400 secondary and collegiate centers of Christian Education owned and operated by the Seventh Day Adventist Church throughout the world.
