In 2018 St Charles East & St Charles North partnered in developing a tournament in town. The St Charles Invitational has 8 programs from around the Chicagoland area. The tournament is played over an 8 day span. The eight teams are randomly drawn into two groups each year (Orange & Blue Group). The Orange Group plays the group games at St Charles East High School. The Blue Group plays their group games at St Charles North High School. There are 3 group games and one cross-over game.
