The decision was announced on Wednesday.
In a unanimous decision by the board of directors, the Boy Scouts of American announced on Wednesday that they will allow girls to join their programs.
The implementation of this new guideline will begin in 2018 for the Cub Scouts and then in 2019, the Eagle Scouts.
The Eagle dens will remain single gender.
“The values of Scouting — trustworthy, loyal, helpful, kind, brave and reverent, for example — are important for both young men and women,” Scouts’ chief scout executive Michael Surbaugh, said in a release.
“We believe it is critical to evolve how our programs meet the needs of families interested in positive and lifelong experiences for their children. We strive to bring what our organization does best — developing character and leadership for young people — to as many families and youth as possible as we help shape the next generation of leaders."
The organization has been trying to make strides in equality. In July of 2015 the group lifted their ban on gay men serving as den leaders.
And in January of this year, they began accepting members based on their gender identity, giving transgender kids the opportunity to join their programs.
