In the mid-1960s the Boy Scouts of America initiated a new approach in their programming. Until that time the Explorer Scout program was outdoor-oriented and aimed at 14 to 18 year old boys pursuing a more advanced experience than the younger Boy Scouts. Exploring became coeducational in the new concept and units were encouraged to develop as career-oriented or special interest Posts.
