I did the German equivalent of those awards, up to what I think must have been the equivalent of either your gold or your platinum - it included all the things you mention, plus some lifesaving training, but not enough to qualify you as a professional lifeguard. I loved them because, unlike most of what we did in PE, they focused on broad competence rather than "higher, faster, better" measures. They gave me a rare experience of succeeding at something physical.
