At 3-4 years of age, the youngsters are presented for Revision at the first level of Breed Grading. This is a physical evaluation of basic race characteristics to determine if they are considered representative of the Breed, and that they do not have any major faults that would disqualify them. Faults that would disqualify include being below the specified height, showing a falling crest, or - in the case of a stallion - being cryptorchid.
Once deemed suitable to continue the breed they are given the Grading 'Basica' – Basic. This is noted in the Stud Book Records, and they are now said to be Revised. In the past this grading used to be known as a horse being 'Apto' - literally, ‘suitable’. This is no longer the terminology used. The Basica is the Basic Grading, and is almost a given. Regrettably, there have been cases of sellers presenting this grading (usually to less informed overseas buyers) as though it were a notable and exceptional achievement. The fact is, probably 98% of PREs pass their Basic grading. It is far more important to note if a horse over 4 years old does NOT have the Basic grading – that could be a warning signal.
