Hi. I think personally, it depends on your relationship with the school, & how helpful they have been in putting in support for your dc.
If, for eg, the school consistently say they see no probs. with your dd& then you explain how difficult things are at home just now, then, yes, you'd probably feel right to feel a bit uncomfortable after filling in the Form. This is because, in a way, it gives the school more ammunition to say all the problems are at home, are there Safeguarding issues?
But, if you have good relationship with school, & explain re home situation, then the assessment would probably flag up that you possibly need some Respite/extra Support for dd at home, & the most likely Agency to become involved would be Social Services.
Don't worry- the assessment is to provide the most appropriate support for you &dd.
My ds has Dyspraxia,(& HFA), & has frequent outbursts at home. He is not violent with us,(yet), but can lash out at his younger siblings, and can scream & shout for ages when upset/ stressed.
Dyspraxia makes dcs very tired, as it takes much longer to process information, follow instruction etc,& along with that, there is usually poor/low muscle tone, so just getting from A-B is far more tiring than for other dc.
Make sure your dd gets plenty of sleep, and plenty of time to relax after school-don't overload her with lots of After School Activities.
As an aside, if the school or any Agency asks you to fill in a form/assessment, always ask what it is for-how is it going to support your dd. And, if possible, take someone with you for support to meetings. Always ask for a copy of the Minutes, & send back any amendments you have. Always keep a copy of any communication you have with school/ other agency. HTH.
