I'm really not - I wouldn't be ashamed if I was, and I wouldn't be surprised if I was in terms of family history - but I do know a lot about autism, being related to and mum to numerous people with it, and teaching many with it too...and I really don't have it!
I think an online test is just that - an indicator test of issues, but no subsitute for a dx. If I had issues anyway, the AQ thing would confirm it, but I don't (well, I do, but not autismy ones except in relation to J!)
I think, when we have kids with autism, it sometimes makes us see it in everyone, even ourselves a bit. For some, that might be true and helpful. For me, it just makes me realise that autism is an extension in many examples of normal traits taken to an extreme level and so everyone has aspects. But it's only when those aspects impair your life significantly that you would seek or question a dx. My aspects, as I've said, are around OCD and control (or the illusion of control in a world where I have none!) and maybe that's where the questionnaire scored me highly, as well as the not liking boring chit-chatty stuff. But I have an excellent social life (when babysitting allows), lots of very close friends, a job where I'm very successful and that success depends on making an emotional connection with children and being able to read children to be able to teach them well and have always been successful socially and academically at school. Not saying this in a smug boasty way but it just all contrasts so much with my AS sister and that's how I can say I have no impairments which would make me ASD .
I wasn't saying people with ASD can't be teachers, btw - there's an article in the TES (Times Educational Supplement) this week about teachers / educational workers with ASD - but the subject I teach and the extra work that I do requires lots of communication and interaction to be successful and I couldn't do it if I met the triad of impairments, iyswim.
