Two assessors – (who have each undertaken a vigorous 2 year long probationary training and probably over seen many an inspection) check the colt against the breed standard and if the colt passes then he will be vetted for defects that may be inherited such as heart, eyes and breeding tackle! and his DNA verified. If it had not already been checked.(Moor bred colts have their DNA tested at weaning) but upcountry bred foals do not get verification except via a covering certificate till they are presented for a stallion licence. Once the above have been fulfilled the young colt will be able to sire ponies who can be registered in the Exmoor pony stud book provided their dam is also of known pure bloodlines.
