Concours de Saut International is a ranking system for the equestrian competition show jumping. All CSI events are approved by the international governing body of equestrian sport, the FEI.
The CSI is broken down into a starring system, where more competitive events with more prize money have a higher number of stars. Starring goes from 1 to 5.
Additionally, speed and height may vary between competitions. For the Nations cup held outdoors, 4* and 5* competitions must ride 400 meters per minute, 375 mpm for 3* competition, and 350 for 1* and 2* competition. All indoor competitions are ridden at 350 mpm.
