Membership in the PEO Sisterhood requires the sponsorship of three women from a local chapter. Through sponsorship, the prospective member is able to get to know the women of the chapter and become familiar with the values and mission of the Sisterhood.
The PEO Sisterhood is an international philanthropic organization that promotes fellowship and higher education among women. It requires personal commitment from its members. During the sponsorship phase, the chapter explains the values of the organization and details the responsibilities and commitments required of its members. If invited to join, the prospective member may make her decision based on the knowledge gained during the sponsorship.
