While Cutting competition is the same (horse, rider, cows, 2.5 minutes) - the classes in which they compete are different. For example, classes can be based on the horse and its earnings, while others are based on the rider's classification and earnings. Additionally, some classes are based on both horse age and rider classifications/earnings.
When discussing NCHA cutting events, you'll usually hear cutters referred to shows as either a "Weekend Event" or an "Aged Event". These two terms simply refer to the type of event. Each of the events will offer different classes you can compete in, depending on your eligibility. This page discussed the differences.
Aged Events place a restriction on the age of the horses.
Usually, these age groups are broken into three rider groups; Open, Non-Professional, and Amateur. Those rider groups are broken down into earnings categories like Intermediate or Limited based on rider earnings. Most Aged Events offer a vast number of horse/rider combinations, and each show is different. Therefore, it benefits a rider to make sure they know their eligibility.
The biggest and most lucrative Aged Events are the NCHA Produced Triple Crown Events.
When someone describes an NCHA approved event as a "Weekend Show", they usually refer to a local event that offers classes for riders with a wide variety of skill levels and horses of any age. The term "Weekend" is a generic term encompassing two different types of shows; Championship and Challenger.
Shows with more than $200 added in the Open and Non-Pro and offer at least an Open, a Non-Pro, and one Amateur class of the 12 "standard" classes are considered to be "Championship" Shows. Earnings in these classes count toward the World Finals Standings. The top 15 placings in the standings of each of the 12 Championship classes are invited to compete at the World Finals. The Youth World Finals are held in July during the Summer Cutting Spectacular and the remaining 10 World Finals classes are held in conjunction with the Futurity in November/December in Fort Worth. In addition, to earning monies toward the World Championships, riders and horses at these shows also earn circuit points which count toward National Circuit Program standings.
Shows that do not offer the minimum $200 added in the Open and Non-Pro, or do not offer the required minimum classes are categorized as Challenger Shows. Competitors in these shows earn points, which count toward the National Circuit Program standings. And while they may also earn monies at these shows, those monies do not count toward World Finals standings.
