RPSI inspections, or keurings, are held in the late summer and early fall of each year at host sites (link to map of keurings) throughout North America. Inspections are judged by qualified representatives of the German parent registry, the Pferdezuchtverband Rheinland-Pflaz-Saar E.V. The same judges inspect German and North American foals to ensure consistency, resulting in fair and ethical keurings. As in Europe, approved mares and stallions are entered directly into the Mare Book and Stud Book and foals are given a registration number at birth. This number follows the foal's show results, location, and breeding records, if applicable.

Inspection days begin with paperwork, where the German Jury will inspect and enter into the database all registration documents, and collect payments. Next, depending on the host site's schedule, mares and mares with foals will be presented, with mares being shown in the bridle and foals beside their dams on a leadline. After the evaluation of conformation, measurement, and drawing of markings, mares and foals (turned loose without the halter) will be presented at walk in a straight line toward and away from the judge, and then on the triangle. Finally, trot and canter will also be judged at liberty. Following the mares and foals, stallion candidates will be presented in bridle, at liberty, and free jumping

Mares must be at least three years of age to be inspected into a Mare Book, whereas stallions aged two and older may be presented for approval into Stud Books I or II. Scores ranging from 1-10 will be given in the following categories:

• Breed and Sex Type
• Quality of Body
• Correctness of Conformation and Elasticity of Gaits
• Walk
• Trot
• Canter
• Free Jumping (for stallions)
• Overall Impression and Development

Stallions eligible for Stud Book I must have an average score of 7.5 or above, with no partial score lower than 6.0. Stallion candidates must also meet Pedigree Requirements. All stallions must fulfill Performance Requirements as well, to complete their licensing. Stallions may be placed into Stud Book II if the Pedigree Requirements for a higher stud book have not been met, if they have an average score of less than 6.0 at their inspection, or if performance requirements are not met.

To be eligible for the Main Mare Book, a mare must have an average score of 6.0 or above, with no single score lower than 5.0. She must also meet Pedigree Requirements. Mares entered into Mare Book and Pre Mare Book must have an average score of at least 5.0, with no single score lower than 4.0, and meet the appropriate Pedigree Requirements.

Foals will be given two scores: 1). Conformation, Development and Overall Impression and 2). Movement and Correctness of Gaits. The foal's total score will be the arithmetic median, with one point behind the decimal. Premiums will be awarded as follows: Gold Premium for overall scores of 8.0 and above; Silver Premium for overall scores of 7.0 and above; and Bronze Premium for overall scores of 6.0 and above.
