Conditions races are horse races for the very best of horses and are split into:

• Pattern Races
  • Group 1 - (Classics and other races of major international importance)
  • Group 2 - (less important international races)
  • Group 3 - (primarily domestic races)
    

and

• Listed Races - have less prestige than the group races but are still more important than handicaps.

In North America, the best horses race in graded stakes races instead of conditions races. The division is similar to that for pattern races in the rest of the world:

• Grade I
• Grade II
• Grade III

Unlike in some other countries, handicap races can be included in the North American grading system; several North American handicaps are Grade I, with more handicaps in the lower grades.
