History of Machakos Girls High School
Machakos Girls High School is a public girls’ boarding secondary school located in Machakos County, Kenya, near Machakos town in the Mumbuni area. The school traces its origins to 1915, when it was established as the Government African School, a boys’ primary school during the colonial period.
In 1946, the institution began admitting girls alongside boys, becoming a mixed school. This marked the first major change in its structure, as it started transitioning toward broader access to education for African learners in the region.
In 1950, the boys were transferred to a separate institution, which later became Machakos School (Boys). This separation led to the development of a dedicated girls’ section, which continued to grow independently.
During the 1950s, the school was reorganized into the Government African Girls Intermediate School, focusing mainly on girls’ education and preparing learners for higher levels of secondary education.
A major milestone came in 1959, when the school admitted its first Form One class consisting of 12 girls, officially marking its transition into a full secondary school for girls. In 1960, the institution was renamed Machakos Girls High School.
