The Boy Scouts of America says girls will soon be allowed to become Cub Scouts and to earn the coveted rank of Eagle Scout, the organization's highest honor. The scouting board of directors voted unanimously this week to make the historic change. 

Chief Executive of the Boy Scouts Michael Surbaugh said today that he hoped the change would "meet the needs of families interested in positive and lifelong experiences for their children." The organization has been primarily for boys, since its founding more than 100 years ago. 

Starting next year, young girls will be able to join Cub Scout units known as dens. Dens will however remain single-gender -- all boys or all girls. A separate program for older girls will launch in 2019, enabling young women to earn the rank of eagle scout. In a statement, the organization said the move reflects the "changing nature of American life."
