Homcaregiver66, I see from your profile you are caring for a partner. Please note that a vast majority of spouses/sig others are not paid unless that spouse/sig other can pay you from their own savings. The is the same thing if an adult child is taking care of a parent, or grandparent, aunt or uncle.
Most agencies will accept your application, and tell you if you need training and where to get it.
You question does not contain enough to give you a better answer than that
