It was established to provide education for boys of the Accra Archdiocese of the Catholic church whose parents could not afford the cost of sending their male children to expensive boarding schools.

Adolph Alexander Noser, the Roman Catholic Bishop of Accra, established the school with a small enrollment of fifty pupils in a two-story home near the seashore in Osu-Anohor.

Thirty-one students and eight staff members attended the school when Father Clement Hotze assumed headmaster duties in March 1954.

Hotze was aware that two key initiatives were necessary for the school to grow properly: government support and West African Examinations Council[1] approval.

For three consecutive years, 1972, 1973, 1974, the school led West Africa in the Advanced Level Certificate Examination according to statistical figures from the Education Ministry.

[citation needed] The school won the Moot Court Competition for the first time the program was introduced to the second educational cycle.
