The Boys' School was established on 5 September 1916,[2] on the ground floor of the residence occupied by Rev.

The Daily Argosy of 8 September 1916, reported that "The courageous venture upon which the British Guiana Mission of the Presbyterian Church of Canada has embarked in New Amsterdam will be watched with greatest interest and sympathy by all whom have paid any attention to the educational problems of this colony.

The High School which has been opened, although interested primarily for East Indians, makes no stipulation as to race or creed.

Encouraged by their success the Canadian Mission Council of the Presbyterian Church of Canada established a School for Girls.

The two schools continued their separate existence until 1924 when a move for closer co-operation was made with pupils of the Fourth and Fifth Forms working together to prepare for the Cambridge Junior and Senior Certificate Examinations.
