I agree - but this is far from an ideal educational outcome as well.you sound knowledgeable, but lumping those students with diagnoses together as ‘disruptive’ is very lazy. Often the the opposite is true, they just quietly zone out. One or two of those diagnosis often get described as ‘well behaved’
not arguing that more couldn’t be done
My comment was to illustrate a potential scenario that may occur in a classroom rather than a statement of fact that those diagnoses inherently produce disruptive behaviour. In many situations, disruptive students often have some sort of (diagnosed or undiagnosed) learning difficulty that has not been adequately addressed by the teacher/education system - which may be any of the three I mentioned - plus many more.
