The Championships began as a standardized sports day for six of Jamaica's oldest high schools, Potsdam (now Munro College), St. George's College, Jamaica College, the Wolmer's School, New College and Mandeville Middle Grade School.
There is evidence of a Girls' Athletics Championships as early as 1914 in Kingston, but after reemerging under different organizations in the 1940s, 1957, then 1961, the girls' event had an unbroken run since being managed by the Games Mistresses Association (founded 1963), a national organization of physical education teachers.
