Depends on how the BSA defines it. If they say any registered member of a chartered group is a "Boy Scout," then she is one. GSUSA says any registered member is a Girl Scout - my husband is one :-).
BSA has several different programs, including Tiger Cubs, Cub Scouts, Boy Scouts, and Venturing Scouts. The Venturing program is relatively new (about four years) but is somewhat similar to the old co-ed Explorer program (which itself still exists as part of Learning for Life) except that it is entirely outdoors adventure and there are no specific Arts, Computer, Law Enforcement, or Fire Fighting groups.
She doesn't have a "Troop," so the reporter is wrong here, too. She has a "Crew." Cub Scouts have Packs, Boy Scouts have Troops, Sea Scouts have Ships, and Venturing Scouts have Crews.
Ages of participation are 14 to 21.
I've had the experience to work with two regional Vice Presidents of Venturing -- each a young lady in her early college years -- and they were dynamite Scouts and tremendous young ladies. In 2000, when hiking at Philmont, I met a crew comprised entirely of young women Venturing Scouts from Stanford (plus, of course, their two female adult leaders. I'd put them up against any backcountry crew of Scouts!
The whole picture gets confusing when you have to talk about Venture Crews, and the shift of Exploring, etc.
But trust me -- she is a Venturing Scout.
