It is hard to believe isn’t it?
There are no licensing or implementation of proof of certification in this industry, in other words, it is unregulated
It is up to us to set our standards.
I suggest getting a certification from a Nationally Recognized Organization and educate yourself to the fullest.
even if you can train somebody without a certification, you cannot get liability insurance (at least not through the agency that is associated with IDEA). That is quite a risk to take.
