KWPN peeps need to weigh in here, but I am wondering if that Ravel son will be able to have KWPN licensed offspring before he has done some sort of performance testing.[/QUOTE]
Assuming the Ravel son completes the endoscopy and semen requirements, he will be licensed and his foals will be Register A. This is the same book that foals by Erkend studbook approved stallions go into. If the Ravel son passes a performance test at a later date, the foal will be moved up into the Foalbook.
The Register A foals can move into the studbook if they complete the requirements not completed by their sire. For the Ravel son, this would mean the performance requirements (if he had not meant them by that point), so either completing the IBOP in their breeding direction or keur level sport requirements, which I believe for dressage is around Third Level.
