If the OT provision is detailed, specified and quantified in F of the EHCP. You don’t need normal NHS referrals, you don’t need or sit on the normal waiting lists and you don’t need to fund the provision. The LA is responsible for the provision. This duty is non-delegable. If the provision in F isn’t being provided, email the Director of Children’s Services reminding them of their duty under section 42 of the Children and Families Act 2014 and asking how they intend to provide the provision. If that doesn’t work, you need a pre-action letter. Then, if that fails, JR proceedings will resolve the situation.
However, if the wording if vague and woolly (for example, including wording such as “access to”, “or equivalent”, “opportunities for”, “as appropriate”, “would benefit from”, “regular”, “up to”, “would be useful/helpful”, “such as”, “e.g.”, “etc.”, “as required”, “as advised”, “key adult(s)”, “small group”) it is not enforceable and you should look to improve the wording via the appeal. The wording being C&P from the report doesn’t necessarily mean it is watertight.
I am not sure what type of resource you want, but the Royal College of Occupational Therapists’ website might help you understand what OTs can help with. Is that the type of resource you mean?
