How is fence work scored in working cow horse competition?

Fence work is scored as the primary athletic and instinct evaluation component of the cattle run, using a scale above and below a base score that reflects average correct performance — the same general scoring approach used in the reining phase. Judges evaluate fence work on multiple criteria simultaneously: the degree of difficulty presented by the cow, the horse's control of the cow throughout the work, the correctness and athleticism of the fence turns, the quality of the rate and acceleration management, and the overall impression of a horse that is working the cow from instinct and training rather than being mechanically placed by the rider. The degree of difficulty component means that a given level of technical correctness receives more credit when the cow is fast, athletic, and challenging to control than when the cow is slow and cooperative — a correct turn on a quick, honest cow is worth significantly more than the same correctness on a lazy cow. Specific fence work errors are penalized: losing the cow to the open arena is a major deduction, as is turning in the corner rather than in front of the cow. Running past the cow consistently reduces the score because it demonstrates a failure of rate and timing management even when the horse ultimately reconnects with the cow. The transitions between fence work phases — from boxing to the drive, from the drive to the first turn, between turns, and from fence work to circles — also influence the score because judges evaluate whether these transitions are smooth, correct, and strategically sound or whether they are abrupt, poorly timed, and reflect a failure to read the cow or the arena situation. The highest fence work scores reflect runs where a skilled, athletic horse controlled a difficult cow through correct, efficient work that appeared effortless from the outside.
