In Norway's youth sports system, score is not kept in children's sports until age 13.
"what is Norway doing that they've dominated the Winter Olympics and they they don't keep score with their kids till age 13. They have national programs that work on development so kids love it and continue to move." (said at 2:27:19)
No published record matching the claim that score is not kept in children's sports until age 13 in Norway was located; this does not prove the claim false.
