ACBL has allocated 24 unit championship sessions per year to each unit. Units may schedule these sessions at their discretion. Units prepare bridge competitions that are suitable for their membership size and for the size and location availability of their playing areas.

Clubs that conform with ACBL regulations that have proved reliable in submitting Monthly Report Forms and fees, and that have an adequate number of tables may participate in these unit championships. Clubs not sanctioned to meet at the times of unit events must be allowed to participate in these events with unit approval.
