Class Equals Competition Level
If you just compare the raw numbers between two horses in a race, you might assume that Horse A, with three straight wins, is clearly superior to Horse B, which has finished third in its last three starts. But once you factor class into your handicapping, the picture can change dramatically.
When people at the track refer to a horse’s “class,” they are talking about the quality of competition it has been facing. In handicapping terms, every race is placed within a hierarchy of difficulty, and horses move up or down that ladder depending on past results, conditions, and trainer intent. Understanding where a race sits within that class structure is essential, because there are multiple levels of competition that determine whether a horse is stepping up, dropping down, or staying at the same level. Here's a breakdown of the different levels:
Maiden Races
These are races for horses that have not yet won. Many horses begin in Maiden Special Weight (MSW) races, which offer higher-quality competition and typically do not allow horses to be claimed. Horses that struggle at that level are often entered in Maiden Claiming races, where the competition is softer and horses are eligible to be purchased by another owner or trainer. Moving from MSW into Maiden Claiming is considered a drop in class.
Claiming Races
Claiming races are among the most common in North America. In these events, every horse is available for purchase at a set claiming price. The claiming price usually determines the class level, so a horse moving into a race with higher claiming tags is stepping up in class, while entering for a lower price represents a drop in class. Trainers sometimes have the option to enter for slightly different claiming levels or weight assignments depending on local rules, but the principle remains the same: the price reflects the competition.
Allowance Races
Once a horse has won a race, it may compete in allowance races, which are structured by written conditions. These conditions often restrict eligibility based on wins, age, state-bred status, or previous race type. A common notation you will see in past performances is something like NW2/X, meaning “non-winners of two races except maiden or claiming.” A horse moving from NW1 into NW2—or from NW2 into NW3—is stepping up in class. Dropping back into a lower-level allowance condition or into claiming company is generally considered a class drop.
Stakes Races
Stakes races represent the highest tier of competition, with graded stakes occupying the top level. Graded races are ranked by difficulty—Grade 1 being the most competitive—followed by lower-level stakes, listed stakes, or races restricted to certain types of horses. Moving from restricted or lower-quality stakes into a higher-grade stakes race is a class rise; moving in the opposite direction is viewed as a class drop.
Now we'll look at how you figure this all out when looking at the past performance information for a specific race.

The first thing to do when reading past performances is to identify the race conditions, or class, of the event you are handicapping. This information appears at the top of each race page. In the example above from the first race at Belmont Park, we can see that it was an allowance race for horses three years old and up, with a purse of $90,000 plus a bonus for New York–bred winners.
The conditions also indicate that the entrants had never won a race worth $10,000 or more other than maiden, claiming, starter, or state-bred allowance races, or had never won two races in total. In the past performance lines, this type of race would be listed as Alw 90000 NW2$/X.
Determining Class in the Past Performance
Once you know the class of the race you are evaluating, the next step is to examine each horse’s past performances. This helps you determine whether a horse is stepping up, dropping down, or competing at a similar level to its recent races. To guide you through this process, we're going to talk you through different horse profiles ahead of a random race found in our archives.
In this race, the #2 horse, Hammerin Aamer, provides a clear example of class movement early in his career.

Hammerin Aamer ran three times at the Maiden Special Weight level, each time for a slightly lower purse. After failing to hit the board in those races, his connections dropped him into a maiden claiming event, where he earned his first win. From there, he moved into allowance company, specifically a restricted starter allowance for NW1/X (non-winners of one race outside of maiden and similar conditions), and won again.
In the race shown above, he was entered in a non-restricted allowance for NW2/X, which represented another step up in class. The market reacted accordingly: his odds drifted from the morning line to a higher price by post time. He finished second, rewarding bettors who believed he could handle the jump.
It’s worth noting that other handicapping factors pointed to improvement—his speed figures were trending upward, and he performed better when stretched out in distance—but those elements are covered in other discussions.
We can look at a second horse in this race for an example of a runner attempting to take advantage of a drop in class.

The #6 horse, Wild About Deb, began his career strongly, winning at the Maiden Special Weight level in just his second start. On the strength of that effort, his connections moved him directly into stakes company, where he competed five times, including four graded stakes and a listed stakes race, the Ohio Derby.
After failing to secure a win at that level and taking a winter layoff, he returned in a much softer spot: a Grade 3 drop into an allowance race for NW1/X. He finished fourth in that attempt.
He was then entered in this race. Having been unable to finish in the top three in the allowance for non-winners of one, the jump into a tougher allowance for non-winners of two did not inspire confidence. As expected, he was up against it. He ultimately finished eighth at relatively short odds, far lower than his morning line price—a sign he was overbet simply because of his past stakes appearances.
Understanding where a horse truly fits in the class structure can help you avoid making the mistake of backing horses like Wild About Deb.
