I'll put my hand up and say we've decided not to pursue a diagnosis for DS even though we're pretty sure he's ND.
Our reasons are:
We have had lengthy discussions with the school and coping strategies are in place. He is managed as though he already has an ASD diagnosis so there's nothing more that would be done that they're not doing now.
DS is high functioning and academically very bright. He loves STEM and knows exactly where he wants to go in life. He always completes tests quicker than the time allocated and often scores 100% in maths.
He's going to private school next year for secondary and the school specialises in SEN anyway so is fully equipped to support him.
When he gets too overloaded he has a day off when needed. He is doing very well in mainstream school and has participated in everything including residentials. He is house captain and is a popular and well liked lad, although he does struggle with groups that are too big in size which is why we're going private for the next phase.
The school have been very candid about the assessment process. There's at least a 2 year waiting list for ASD assessment and there's no extra funding anyway. Getting him diagnosed would literally make absolutely no difference to him at this stage.
If he needs a diagnosis for a tangible reason late on we will get one done privately but at this stage there is literally nothing that we're not already doing to support him.
There's no stigma or over riding reason other than we have a plan in place and it's working for him.
I also don't want to clog up the system when others need to get assessed more than he does.
Judge away. It makes no difference to us or would change how we as a family are supporting him.
