British Dressage 

How to choose a competition class: 
 
Firstly you need to work out which level and section you're eligible to compete in, which is based on both yours and your horse's previous achievements. The best starting place for this is to look at BD's eligibility guides. 
Take a look at the qualification period for each of the competitions and where and when the qualifiers are, this will help you decide which competitions you have time to get the required scores for. Also bear in mind that you can often use 'normal' outings to qualify for a number of different championships, such as the Petplan Area Festivals. 
 
Next, choose which test you want to do. You can choose your test depending on your level, the lower the number the easier the test. So if you’re just starting out at Prelim level, try Prelim 2 before making your way up the numbers towards the more detailed tests for each level. You can buy test sheets and plans from the BD online shop, or if you prefer a more interactive way of learning try the Dressage TestPro app!
