World Class corps can have up to 150 members. Students in World Class corps are primarily college-age with some high school involvement. Most corps from this class follow an intensive tour schedule, traveling more than 10,000 miles over the course of the summer while performing at more than 35 sanctioned events.
The criteria to earn World Class status incorporates a combination of aspects that include organizational stability, strength of program, number of participants, touring capabilities and financial stability. A participation review process is managed by a committee of independent individuals. They perform exhaustive evaluations of corps petitioning for World Class status after which a recommendation is presented to the DCI Board of Directors for a decision.
