Junior I couples are allowed to compete in Junior II, Junior II couples are allowed to compete in Youth, Youth couples and Senior couples are allowedto compete in competitions of the Adult age group if wanted. It is not allowed that Juvenile II couples compete in Junior I age group on the reason of the syllabus. In all age groups one partner of a couple can be younger, except in the Senior age group.
The table as given above will make easier the understanding of Rule 11.
This regulation enables couples and coaches to plan on a long term basis because the classification of competitors doesn't depend on their birthday but on the year of their birth. It is usual in many sports!Heinz Spaeker
