It competes as part of the Ohio High School Athletic Association (OHSAA).
The Akron Beacon Journal began naming an "All-City Team" that year and the schools all had a playing field of their own.
Kenmore, which had opened in 1916, and Ellet, which dated to 1891, were annexed into Akron in 1929 and joined the City Series in 1930, and Buchtel opened in 1931 and joined in 1932 to briefly bring membership to 10 schools.
The league returned to nine members in 1963 with the opening of Firestone High School and remained at nine until 1970.
The City Series briefly dropped to eight members again in 1970 when Central and Hower Vocational High Schools were closed and merged to create Central–Hower High School, but again returned to nine members when Ellet High School rejoined the league in 1971.
