The term “Partners in Service” refers to the subsidiary groups that Rotary clubs organize to help spread the ideals of Rotary in the community.  Strictly speaking, partners in service includes:  Rotaract Clubs, Interact Clubs, and the Rotary Community Corps. 

Rotaract clubs are youth groups aged 18-30 sponsored by a Rotary club.  The first Rotaract club was formed in 1968 at South Carolina, USA.  As of December 2003, there were 7,482 Rotaract clubs with 172,086 members in 155 countries.

Organizing a Rotaract club is one of the most rewarding activities a Rotary club can undertake in its community.  The Rotaract program gives Rotarians the opportunity to mentor dynamic young men and women.  Rotaract clubs organize a variety of projects and activities.  RI has however asked all Rotaract clubs to focus on a balanced program for the following three areas: professional development, leadership development and service projects.

Rotaract clubs may be organized in a school or could also be community-based.  These clubs must meet not less than twice a month and a member of the sponsoring Rotary club should attend in at least one of these meetings.

Interact, the Rotary youth program, was launched by the R.I. Board of Directors in 1962. The first Interact club was established by the Rotary Club of Melbourne, Florida. Interact clubs provide opportunities for boys and girls of secondary school age to work together in a world fellowship of service and international understanding. The term, Interact, is derived from "inter" for international, and "act" for action. Every Interact club must be sponsored and supervised by a Rotary club and must plan annual projects of service to its school, community and in the world. As of December 2002, there were 8,783 Interact clubs with 202,009 members in 111 countries. "Interactors" develop skills in leadership and attain practical experience in conducting service projects, thereby learning the satisfaction that comes from serving others. A major goal of Interact is to provide opportunities for young people to create greater understanding and goodwill with youth throughout the world.
