Not sure about the ATA, but WTF does not allow punches to the head because they want to emphasize kicks and make the sparring style kick-only-boxing. Personally, I think that 'Taedo' would be a more accurate description of WTF sparring, as the kwon (fist) is relegated to punch pushes. I say punch pushes because pushing isn't allowed, but punches aren't scored for the most part, no matter how far they move when you hit them.
