A horse with a ster predicate has above average con­formation and movement and/or jumping. The ster predicate is awarded at studbook inspection to stallions, mares and geldings that have earned minimum of 70 points for conformation and minimum 75 points for movement or jumping. Minimum required height is 160cm.

If a horse earns 70 points for conformation, but less than 75 points for movement or jumping, it can earn the ster predicate by passing the IBOP test in the same breeding direction.

A predicate for ster mares that are keur eligible, having conformation higher than for ster, and that have completed IBOP performance test or equivalent sport requirements.

A predicate awarded to keur mares that have also completed the PROK requirements.

A predicate for KWPN Foalbook or Studbook, Register A, Auxiliary Foalbook or Auxiliary Studbook horses that successfully complete the IBOP riding or driving test. Combined with keur eligibility, this predicate would count toward keur.

PROK stands for Project Röntgenologisch Onderzoek KWPN (Project Radiographical Research KWPN). The breeding purpose of the KWPN states, among other things, that it wants to breed healthy horses. The PROK predicate is awarded to horses that meet the KWPN’s radiograph requirements (same rigorous examination as KWPN approved stallions) . This means the horse has good bone quality, which—if bred—it can pass on to any potential offspring. The radiographs are evaluated by an independent KWPN committee, and with a positive evaluation the PROK certificate is awarded.

A predicate awarded to KWPN registered mares that have three offspring earning a combined minimum of five points as earned through specific performance criteria. The predicate may also be awarded posthumously.

A KWPN-NA performance predicate awarded to stallions, mares and geldings competing at FEI levels. Horses must be within the 300 top-ranked dressage or jumping horses in the WBFSH/FEI rankings.
