Steward statement template

For a mass participation record we require Stewards to supervise groups of 50 or fewer participants, in order to disqualify any attendees who do not successfully take part in the record attempt. Please give your Stewards these templates to fill out. You need to upload all Steward Statements as part of your evidence. If your mass participation record involves more than 5,000 people, the counting process must be done by an auditing firm and it is still compulsory to submit steward statements in addition to the auditors’ report.
