Although patterns are used in technical training and as part of grading exams they can also be performed in a competitive environment. At local and club level patterns can be part of a competition and they are also competed at high levels with Commonwealth, European and World championships.
Patterns can be open where you choose your own form to perform, or you may need to perform the pattern for your grade. Some clubs may teach patterns with weapons and in some competitions there is a category for this although it is less common. Another way that patterns can be performed is in teams or pairs, this is commonly referred to as synchronised patterns.
