The Wykeham Collegiate was founded in January 1990 with the amalgamation of Wykeham School, founded in 1905, and Girls’ Collegiate School, founded in 1878. The decision to amalgamate these two schools was taken by the respective Boards of Governors in 1988. During 1989 the relevant buildings were constructed, and the new school welcomed its first pupils on 25 January 1990. The school quickly became recognised as one of the leading independent schools for girls in Africa.
