The Arena Rating System (ARaS) is a universal, up-to-date program which rates a particular arena's difficulty. Variables factored into the rating are: surface conditions, obstacles, levels, jumps, and arena space. Additional information on medical facilities, weather conditions, tournaments, statistics, and the local competition are included as well. The ARaS scale runs from 1 (easy) to 10 (dangerous).
AADA statistics have shown that the casualty rate increases 10% to 15% for each level of additional difficulty.
| ARaS | Difficulty | Casualty % |
| 1-2 | Easy | 20-40 % |
| 3-5 | Average | 41-55 % |
| 6-9 | Difficult | 56-65 % |
| 10 | Dangerous | 66-80 % |

| Arena | Rating | Arena | Rating | |

| Hammer Downs | 6 | Dumbarton | 8 | |
