Following a discussion with a colleague recently, I ws wondering if anyone could shed more light this subject: Who is responsible for the visiting staff on an Outdoor and Adventurous Activity, when the providers are using 'remote supervision' with the participants, and have no requirement for the visiting staff to be involved? An example could be a Duke of Edinburgh Award Expedition, where providers are remotely supervising participants, and a member of visiting staff - who may be a keen hill walker - has expressed an interest in walking up on the mountains and meeting the group/s. Another example could be water based, maybe on the river, where a member of staff has expressed an interest in canoeing, but not with the group and, although capable, has no real qualifications or skills awards in that environment. The supervisors in both examples would, ideally, be focussed on the participants safety and well being, and planned for this with ratios etc. Do schools and colleges have their own guidlines for staff, or is it down to the provider?
