In 2002, existing Leo clubs declared themselves as either Alpha or Omega Leo clubs.

Members of Alpha Leo clubs are between the ages of 12 and the legal age of majority in their country.

Omega Leo club members are between the legal age of majority in their country and an age deemed appropriate by the multiple district. All other requirements are identical for Alpha and Omega Leo clubs.

All Leo clubs have been asked to declare their clubs as either Alpha or Omega Leo Clubs. Age-appropriate publications will be mailed to Alpha and Omega Leo clubs.

Alpha Leo club advisors will accept a more active role in guiding young Leos to plan effective meetings and successful service projects. Omega Leo club advisors will serve mainly as liaisons between the Leo club and the sponsoring Lions club.
