Girl Scouts of the USA is the world's largest organization for girls - just for girls - serving over 2.7 million of them around the globe through a program of five levels that span ages 5 to 17. The Girl Scout Research Institute explores issues affecting girls and encourages practical applications to benefit them. Girl Scouts is also where girls turn to discover the fun, friendship, and power of girls together. Girl Scouting gives girls opportunities to build skills for lifetime success. Whether in science, sports, or the Girl Scout Cookie Sale, scouting shows girls how to set goals and reach them.
