There has been a bit of a delay this year, for obvious reasons, but the 2021-22 handbook is now available for download.

The only significant changes are grading/progression allowances for COVID impact on training, and the rules on attire (to match BG).
Please read them carefully and if you are uncertain, please check with your regional trampoline competition organiser.
