Historical Background
Alliance Girls High School sits on 71 acres of land and was the first African Girls High School in Kenya started for the African girl child by the Scottish Missionaries. The Presbyterian Church gave the land on which the school stands today and has remained the sponsor to-date.
The first 10 girls to the school arrived on the 28th February 1948. These girls were drawn from the different provinces in Kenya. This national outlook has been retained to-date. The school has a strong Christian tradition and way of life.
