The school on inception was populated by eight (8) pupils and a teacher: The visioner - Mrs Elizabeth Otobotekere Geoge and one Miss Christina Kinane who was assisting.
By the year 1996, the school population grew and there was need for more teaching staff as well as classrooms accommodation. The NAFCON authority gave approval for extension in the number of classrooms after Mrs. Geoge (the visioner) request for.
More seasoned staff members where hired, including the likes of the pioneer dynamic school head Mr. Emmanuel Nwinabiimene Vidaa - That was in 1996.
