The criteria and definition of a "good parent" is way too broad and subjective. Sure there's the "exception" options, with qualities that unanimously are agreed as being bad for child rearing. But, what about raising kids religiously? Doing certain surgeries on them, or refusing certain medical procedures? What about different views on the importance of education?
All I can see a license doing is simply trying to prevent the certain "exceptions" from happening (negligence, abuse, etc). But, I don't think that'll really help, as those "exceptions" should be common sense anyway.
