This marks the fifth year for the men's championship and the inaugural year for the women's championship.
Intercollegiate associates are non-varsity teams that compete for colleges throughout the country.
There are over 100 men's and women's programs each. Earning the top seed in the 16-team men's draw was the University of Michigan, which is making its third straight trip to St. Louis after winning the Central Collegiate Lacrosse Association title. Defending national champion BYU is seeded second and 1999 champion Colorado State drew the third seed. Both compete in the Rocky Mountain Lacrosse League. The men's championship will begin play on May 8.
