The biggest trials in the UK and Ireland are the ISDS National and International Trials, held every year. There is also the ISDS World Trial, held every three years, the next being in 2008.
For details of these and the annual Continental Trial visit the Major Trials page.

There are hundreds of local trials held every year, ranging from small events with few facilities up to medium and large size events with catering and often other side events to keep the interest not only of dedicated sheepdog people but also of the more cosmopolitan members of the general public.
The current list, divided into regional groups by date is to be found on the Local Trials page.

For the latest trials news, updated fully every Tuesday morning, and again during the week as new information comes in, visit the Latest Trials News page. The details from this page are transferred to the other trials diary pages immediately before the following Tuesday's full update, and the Latest Trials News page starts again from new.
