What are the Dutch dressage levels English equivalent?
Hi all,
I am riding a horse that was imported from Holland at the moment and after looking on the KWPN database I found out that his sport level is: DR NED ZZL
If anyone could tell me what this means that would be great, I know he was a dressage horse if that helps, thanks

DR - dressage
NED - Netherlands
ZZL - ZZ Light (Medium / Advanced)
