At the 2022 Annual AHA Convention, the AHA Futurity Commission reviewed the participation in the Performance Futurity/Maturity/Derby classes. Due to consistently low participation, the following classes are currently on probation:
Arabian Herd Work Futurity (Class 509)
HA/AA Herd Work Futurity (Class 510)
Arabian Working Cow Horse Futurity (Class 262)
HA/AA Working Cow Horse Futurity (Class 1923)
If participation does not increase to 8 or more entries per class, for the 2023 US National Championship Show, these classes will be discontinued beginning in 2024.
