TREC GB score calculator.
Work out a TREC GB percentage from the marks on your sheet. 3 current tests are built in with their movement counts, coefficient movements, collective marks and sheet maximums, and TREC GB's own error of course rule is applied automatically. Free, no signup, and it keeps working with no signal.
Every TREC GB test this calculator carries.
Pick any test below to open the calculator with that sheet already built. Structure only, read from the published sheets: how many movements, which are doubles, the collective marks and the printed maximum. The wording of a test belongs to TREC GB and is not reproduced here; you ride with the paper sheet in front of you. Every maximum below was checked against the sheet before it shipped.
| Test | Level | Arena | Movements | ×2 movements | Collectives | Maximum |
|---|---|---|---|---|---|---|
| VTH In Hand / Lead Rein Obedience Test (sample) (2026) | In Hand / Lead Rein | 10 | none | 0 | 100 | |
| VTH Novice Obedience Test (sample) (2026) | Novice | 20x40 | 15 | none | 0 | 150 |

TREC GB scoring, answered.
How many marks is an error of course under TREC GB rules?
TREC's control of paces has no error-of-course rule: breaking gait or leaving the corridor zeroes that stage instead.
That is the rule in the British TREC Rulebook 8th edition, Rules 5.6 / 6.7.5 (Effective 1 Apr 2026), and the calculator applies it automatically. Rules get revised, so where your rule book or sheet differs, the sheet is right.
Which TREC GB tests does the calculator include?
3 current tests, covering In Hand / Lead Rein, Novice and Open, each listed above with its movement count, coefficient movements, collective marks and the maximum printed on the sheet. Every maximum was checked against the published sheet before it shipped.
