The competition begins with a round robin league phase to qualify for the knockout rounds. It is the most watched and prestigious school and college competition in Karachi, which is played by the top schools and colleges.
Introduced in 2005, it was a way to promote football for students in their O and A Levels. The competition took inspiration from the college football held in the United States and Canada. The competition aims to find new talent for the Karachi United professional teams as well as raise the standard of football in the country.
With the objective of providing a forum for students to play competitively in a safe and professional environment, Karachi United provided a platform for students to showcase their skills and talent in a bid nurture and harness football talent at the school/college level. It has since become the premier school/college competition with inter school and inter college rivalries developing over the years and bragging rights to fight for during the tournament.
The inaugural KUSC was held in 2005 with the senior boy’s category being held. Over the years, the tournament has grown in number of teams and categories. To promote football among girls and the younger students, the introduction of the girl’s category, senior and junior, and the junior boy’s category were introduced. The 2014-15 season saw the introduction of the senior girl’s category whereas the junior boy’s category and the junior girl’s category was introduced in the 2018-19 season and in the 2023-24 season respectively.
