AIBU to think that BOSA assessments for autism are a waste of time?

[Rushhomeroad]

My DD11 has an appointment later this morning for a BOSA assessment for autism. From what I've seen on the information video it is me playing and talking to my DD for 15 minutes whilst being watched for indicators of autism. If she can mask all day at school, what chance is there the BOSA assessment will identify anything? School are not helping as she is not disruptive in class, so they see no problem - I expect their paperwork will say no signs.
Anyone found a BOSA useful?

I work in an adjacent field. My understanding was that BOSA is part of a larger clinical assessment but introduced to limit face to face time because of Covid. However I don't think they are only supposed to be 15 minutes? More like an hour?

Thanks for replying. The video sets out what happens in the assessment - 6 minutes to play jenga, 2 minute conversation etc, which totalled 15 minutes. We've had the assessment now and it was actually 2 1/2 hours, so much more time to do everything. The nurse was great, and I'm a little more hopeful that it will help towards a diagnosis now. Still a long wait for the Paediatrician now though.

You could argue the same for ADOS. The assessments are structured to promote behaviour which will highlight differences. The clinicians are highly trained to spot subtle differences. I know what a worry it is wondering how 'they' will see what you can see though. I hope you get some answers soon

DS masks well and I was stunned at how readily he was diagnosed.

The consultant saw subtle details like the way he'd focus on me while talking to her, the nature of his interjections into the discussion, and his response to direct instructions and not picking up assumed cues like sitting himself down after being measured.
Because I'm one of his "safe" people that he makes eye contact with, I'd never spotted that he overly does it with me to compensate for not looking at strangers. I notice it all the time now it's been drawn to my attention.

The professionals know what they are looking for and teachers are generally looking at the way behaviour affects classroom performance.

Thank you, that's reassuring. There were some of her quirks shown, but you never know what others notice. The nurse was chatting at the end and was asking if how she was, was how she is at home. Whilst I was answering her, DD was lining up the small metal balance bars in size and shape order! I'm hoping she saw enough - my daughter has said that if they don't find a problem it just means she's stupid 😞
