My colleague, KJ is trying to respond but her comment is getting stuck in moderation!  there is also a book you may be interested in called Safe at the Pool, Cerberus Printing 2017

<div>I have had this situation and the school asked if I could talk with the pool, which I did (of course...I like a challenge)! The pool manager was interested and agreed to meet me. I said we could supply a portable changing bench (similar to the fold up therapy bench physiotherapists carry), portable hoist and mobile pool hoist, if they were prepared to find appropriate storage (with power sockets for charging hoists) and a space for changing. The pool had a rather large changing cubical (family sized) and they agreed to actually put in a height adjustable shower bench themselves into this space...this all worked for four years, while the child went swimming from year 2 to year 5. To summarise, it might be worth talking with the pool about their options for improving accessibility. As a specialist teacher, I had no jurisdiction over the pool or ability to fund adaptations, including the fitting of hoists or a changing bench. Each item I was offering was portable, so could be taken away and stored when not in use.</div>

As a specialist teacher working for the local authority I had no jurisdiction over the pool and could only offer portable equipment, on loan from Essex, for the child to use. As a public place the swimming pool should have an accessibility plan and make reasonable adjustments.</div>

The comments above are very similar to our experiences. I would advise school to look and see if there are any alternative pools that are more appropriate. We do sometimes ask schools to contact the local special schools to see if they could access their pools for a particular young person if there is no practical way of them attending with their peers.
