Are courses targeted at taking care of someone good for learning social clues?

I was looking for some weekend classes, ans there are many courses like "Child caretaker", "Elderly caretaker", or for people with disabilities.

Technically, per description, I don't need any previous experience with those groups to take those classes, but to be frank, I never took part in any course like this and have no idea how it work. I'm not great at masking or making conversation, and I wonder if attending would just single me out for being an awkward one, or maybe they will show techniques that would help with it? Like, let's say kids, methods to calm them down and what "signal" means what?

Anyone have any experience with this? Does it even sound like a good idea?
