At my children’s school their transcript that is sent by the counselor to their colleges, it lists not just grades but extracurriculars. So if it’s a school related extra curricular it would be on there. If it’s not part of school (Girl Scouts, travel soccer team, volunteer work with church…) then that would be something that someone could more embellish if they chose to. But let’s say you claim to be an Eagle Scout or Gold Award Girl Scout, that’s something that’s easily verifiable by a college.
