School history
Mang’u High School traces its start to 1925 at Kabaa, in Mwala, Machakos County, where the Holy Ghost Fathers (Spiritans) ran a Catholic school that trained catechists. After a pilot class of four pupils in 1929, the high school opened officially in January 1930 with 27 boys. At the end of 1939 it moved from Kabaa to Mang’u, and in 1951 it became, by the school’s account, the first African school in East Africa with a full course in physics, chemistry and biology.
The school moved to its present campus near Thika, in Kiambu County, in 1972. It started its air programme and its radio and electronics clubs in the early 1960s, launched the Moi National Mathematics Contest in 1996, added its chapel in 2002 and opened a French language resource centre in 2011.
Today it is a national boys’ boarding school sponsored by the Roman Catholic Church. Its motto is “Jishinde Ushinde”.
