Some of the schools that participated in the Cook County League still exist today: Crane (as English High and Manual Training), Englewood, Lincoln Park (as North Division), Hyde Park, Phillips (as South Division), Calumet, Marshall, Austin, Lake (now Tilden), and Lake View.
However, when the CPL schools began joining the IHSAA in 1926 (so as to participate in the state golf, tennis, and track and field contests, in which the IHSAA that year assumed joint sponsorship with the University of Illinois) the league then ended its sponsorship of girls' golf, tennis, and swimming, and cracked down on girls' interscholastic contests in the other sports.
Beginning with the Great Migration coming in the 1920s, a number of schools became predominantly African-American, notably Phillips (started as South Division), DuSable (started as New Phillips), Dunbar, Forrestville (now King), Carver; and later into the second half of the 20th century with Julian, Simeon, Curie, Orr, and Kennedy.
Davis, who has 25 years of teaching, coaching, and administrative experience in the Chicago Public Schools took over in 2003 after being selected by CEO Arne Duncan to replace Dr. J.W.
Some coordinators handle multiple sports: one example is Mickey Pruitt, a graduate of Robeson and former member of the Chicago Bears.
David Rosengard currently serves as the Executive Director of Sports Administration for Chicago Public Schools.
Since 2004, it is now made of black marble with gold trimming and plated with a silver sculpture of the sport the trophy was earned in.
Between 1972 and 2002, the holder of The Shield gained automatic entry into the Illinois State Finals in most sports (except football).
With the exception of soccer, football, girls basketball and baseball, each sport in the CPL has two distinct playing divisions: Red and Blue.
The Red division is considered the highest level of competition citywide, while the Blue features programs just starting or not quite as talented.
The game would be later dubbed the Chicago Prep Bowl in 1934 by Mayor Edward Kelly as a Thanksgiving fundraiser for the city's poor.
On the city level, football has been long dominated by schools south of Madison Avenue, but north side powers like Lane and Schurz have also hoisted The Shield as league titleholders.
As of the end of the 2006 season, Chicago Vocational holds the record for most football city titles with nine, with Lane and Julian tied for second with eight.
In addition, the advent of the Chicago Conference Championship game in 2004 has given the second division an opportunity to earn at least one piece of hardware before being seeded into the Prep Bowl tournament.
Among the stadiums used to stage the city championship were the Chicago Coliseum, International Amphitheater, the UIC Pavilion, and recently the United Center.
When the boys championship was contested for the first time at the United Center in 2000, the league set a new state attendance record in basketball as 20,002 patrons watched Westinghouse earn the crown against Whitney Young.
As of the 2010-11 school year, the Jones Convocation Center at Chicago State University is the current host of the CPS basketball title games.
The league has had its share of state titles, with Lane, Fenger, Schurz and Hubbard taking their place atop the podium.
Between 1972 and 2002, the CPL had enjoyed status as sending its city champion to the Illinois State Finals in numerous other sports, including soccer, wrestling and softball.
