However, the move to allow girls to join doesn't mean Boy Scouts will suddenly be filled with co-ed troops. Rather, as plans have crystalized, leaders have said the troops will remain single gender. Cub Scout dens for ages 7 to 10 can be all-boys or all-girls starting next year. It will likely be similar for girls 10 through 18, who will be able to join Boy Scout troops beginning in 2019. Details of what that looks like haven't been finalized, but it will have a similar curriculum to Boy Scouts and allow girls to earn the top rank of Eagle Scout. Boy Scouts have, for years, opened up certain programming to girls, such as its Venturing program, which in Carroll County has produced the multi-time state champion Envirothon team.
