Junior Girl Scouts are girls who are in grades 4-6. A minimum of two adults lead each troop. Junior Girl Scouts earn recognitions called "Proficiency Badges" as well as other leadership awards.

A "Proficiency Badge" is earned by completing a minimum number of requirements and demonstrating proficiency in that particular area. Girls earn these recognitions in many areas, including: computers, photography, the arts, ecology, outdoor activities, and sports.

Girls participate in community service projects, use a form of democratic government called "patrols," and elect leaders within their group who represent their interests at a "Court of Honor." Junior Girl Scouts make shared decisions with adults and learn to keep track of troop finances and travel more than Brownie Girl Scouts.

Their adventures may take them close to home or on out-of-town trips to such places as the Juliette Gordon Low birthplace in Savannah, Georgia or Space Camp in Huntsville, Alabama. Junior Girl Scouts participate in the annual cookie sale, calendar sale and sometimes a special troop fund-raising project. These funds support troop activities.
