Parent on duty must complete the relevant training session 'Self-screening' form which can be found here

Each training session must have a Parent on Duty/Pool-sitter to oversee the session in line with Swim Ireland’s Supervision Policy. This ensures someone is on hand for any problem that might arise. In the absence of a pool-sitter, the associated training session will be cancelled. It is the named pool-sitter’s responsibility to find a replacement if they cannot attend.
