In the first instance ensure there is a thorough risk assessment in place for the child to demonstrate you have taken reasonable steps to ensure safety. Include parents in this as they’re really helpful in thinking outside the box. Encourage parents to ask GP for NHS OT referral. As previously stated, many of the measures you put in place will be echoed in the OT report once it arrives but in the meantime you are a) getting ahead of it b) reassuring parents c) ensuring the child is safe and school are covered from a safety and safeguarding point of view should anything happen.
(I have a pupil with hypermobility, OT was done via NHS. The risk assessment when done with parents turned out to be more thorough than the OT recommendations!)
