Originally from Blackburn, Singleton decided to form a small primary school during the Great Depression due to a perceived lack of alternatives in the local area.

She began by offering space and education to a small group of local children in her parents' house, Westholme, located on Preston New Road in Blackburn.

By 1948, the school had increased enrollment to around 135 pupils and was officially recognized by the government as a formal place of education.

She agreed with World War I veteran Mr. Arthur Rouse, who became the new school principal, joining from the University of Salford.

In 1968, the school became a charity administered by a board of governors, and a sixth form was established along with a ten-acre site-building program that included an assembly hall, laboratories, a swimming pool, a sports hall, playing fields, a music center, and art studios.
