Extended Schools person spec form... help!

[Alambil]

The form says I can use every day life in examples for the role (support worker)

so, DS is dyspraxic (well, dcd) and so I've accessed support for him in school and with therapists - could I, if I need to - use that as a "I realise the barriers / help out there" example or do I need to use something a bit more professional?

I don't see why not. It gives you an invaluable view from the "customer side". Sounds really good to me.
