For each on-site training day, team members who wish to attend should pre-register to receive a visitor QR code. Visitors may be required by the venue to upload their vaccination record. As the capacity is limited, we may limit the number of attendees and team members may be restricted from future on-site training sessions if they do not attend after registering.

The Team Formation Test will be held on-site. The test will be postponed to the next reserved day if required. Team members can expect to see vaccination requirements in the selection criteria for external competitions.


Attendance will be taken. Only Training Team members and non-trainees who attend at least one regular training session may participate in the Team Formation Test.
