The Badminton England age groups are set around both the international age groups and the domestic season.
The international season runs from January to December and the domestic season runs from July to June. The age groups are determined by using the 31st December at the end of the year which the season culminates so that players continue to compete in the same peer group both domestically and internationally.
Therefore players will move up an age group in the domestic season 6 months before the international age group, meaning they will be accessing more competitive domestic competition. This supports the overall standard so that players will be better placed to compete internationally, reach senior level earlier and may help reduce the current standard gap between junior and senior transition. This will support the long term success and profile of English badminton.
