In common with most disciplines of dog training, Agility is administered on a national basis by the Kennel Club.

The rules, regulations and equipment specifications are defined by the Kennel Club in their Annual Year Book which is published in July each year. These rules have evolved over the last 30 years as a result of consultation with Agility Clubs via an Agility Liaison Council. Currently, Agility caters for three sizes of dog: Small (measuring 13.75 inches or under at the withers), Medium (measuring over 13.75 inches but under 17 inches at the withers) and Large (measuring over 17 inches at the withers) and classes are scheduled for each category.

Competitions are further divided into 8 classes: Elementary, Starters, Graduate, Novice, Intermediate, Seniors, Advanced and Championship.

Dogs are promoted to the higher classes by a system of 'winning out' although, up to Intermediate, the handler may elect to adopt a points system to progress.

The British Agility Club has over the years undoubtedly contributed most to the sport. It is the only organisation that organises seminars for both Agility Judges and Agility Instructors.

As anyone who has attended any of these training courses will testify they are demanding, thorough and comprehensive. To pass the examinations required to become an 'Agility Club Qualified Judge' or 'Agility Club Approved Instructor' requires a high standard of both theoretical knowledge and practical ability.

There are only two publications in the United Kingdom that are dedicated to Agility. One is the 'Agility Voice' published by the British Agility Club and the other 'Agility Eye'. Both magazines organise league tables and prizes for subscribers.
