All well and good and who would disagree with the need for effective support rather than just a 1:1 on a bit of paper.
However, while the need for effective interventions and measurable outcomes is self-evident, achieving them is not always easy particularly if neither schools or professionals know what to do about a particular issue.
That is a far from uncommon situation and pretending we could have all the answers if we just tried harder or commited time to our child or just did it ourselves is fallacious, dismissive and a bit patronising.
It might be straightforward with more tangible problems like reading and writing or difficult behaviour issues people can see but other issues are not so clear cut.
I have given extensively of time at home and at school to the detriment of my own career. I look for my own answers as professionals haven't a clue. Sometimes, I can figure out what to do and can work on things myself and get school to as well. Other times, there is no easy solution.
I know Moondog, you will say you would work it out but you are not here and no one here as that confidence or perhaps skill. The ABA therapists I have tried, although highly qualified and well-known, haven't a clue how to teach with teaching skills to children with Asperger's either.
So, yes, of course targets should be SMART and support should be effective and we shouldn't waste time on things that don't work etc etc but saying that is not the same as working out a concrete plan of what needs to be done and how.
