The first participating countries in the ETU were Spain, Belgium, Austria, Portugal, Germany, Italy, France, Netherlands, Turkey, Greece, Denmark and the UK.
Gradings are typically held in 3 month cycles at regional training centres.
Grading systems will typically consist of line work, patterns, theory, and sparring.
Although it is possible for students who perform exceptionally well during their grading to 'double promote', this means that they gain 2 Kup instead of one.
this is however not very common and is only done if the student has exhibited complete understanding of the material they are being tested on as well as control and maturity.
