Someone I know asked me for advice about this.. but as a parent it's hard enough to access sources to find out the things we need to know.. (or perhaps it IS harder for parents anyway..)
Her mindee (think this is the right term) is currently starting the (no doubt long) process of being diagnosed with autism. He had quite a lot of additional needs already even though he is not yet three. Friend really wants to learn about how to meet those needs and is aware that really he needs one-to-one care which she would be prepared to provide (although she should get paid extra for this I think?)
Not sure if this really needs to go on SN where there will be parents with AS experience.. but thought I would ask the childminding community of MN first. She doesn't know who to contact to get the training she knows she needs and everything is a bit up in the air with the mindee's family at the moment as they struggle to come to terms with his problems.
