The first greater Kansas City Mathematics Technology EXPO was held in 1991 at Johnson County Community College in Overland Park, KS. Initial sponsorship for the conference was provided by the Kansas City Regional Council for Higher Education (KCRCHE). The EXPO has been an annual conference ever since.
In 1992, the second EXPO moved to Kansas City Kansas Community College. When KCRCHE was dissolved in 1994, the EXPO became a self-supporting event. All succeeding EXPOs were held at Kansas City Kansas Community College until 1997, when the EXPO moved to the new Science Center at Rockhurst University. The name of the EXPO also was changed in 1997 to the Kansas City Regional Mathematics Technology EXPO, and incorporated as a 501(c)(3) non-profit corporation.
In 2009, the EXPO moved to the University of Missouri – Kansas City, across the street from Rockhurst University.
During the time since 1991, the EXPO has grown from a one day event with an attendance of 56 people to a 2 day event with an average attendance of over 100 people, with regular and new attendees on average from about 25 four-year colleges, 15 two-year colleges, 10 high schools, and 10 states.
