School teacher implying ASD

[Cookies23]

I'm new here so hope I'm posting in the right place! I could do with some advice. My DS (5) has just started school. He has an IEP as concerns were raised at Nursery. We since had a referral from GP to Peadiatrician who on first meeting discharged us as he thinks DS is essentially fine.
My sons teacher (also the SENCO) doesn't seem to agree with the peadiatrician. She has implied on several occasions that she thinks it's wrong. DS does get OT and there are some issues but I'm quite sure he is not on the autistic spectrum. She has asked me to write a letter supporting help from the local (LEA?) autism service. I've refused and am a bit annoyed asi don't want my son inappropriately labelled.
Anyone experienced this before, not sure why school would want to push a label on a 5year old?

The Paed can only go on his impressions of your DS in a clinic room. The SENCO sees him with his peers and in a group setting.

If you have concerns raised at two settings, I'd be inclined to allow the LA Autism service to meet your DS - they'll be absolutely swift in getting him off their books if the referral is inappropriate, believe me!

Good point, I guess I'm a bit annoyed that she has mentioned a particular diagnosis herself. It seems out of her remit.
My brother is a consultant peadiatrician and has always said DS is essentially ok. I've even tested him myself on AQ and various other tests and he really does not look like he's on the scale. Is it not better to get him evaluated by an Ed psych if they have concerns?
The teachers have recently been on a 'course' and I appreciate their intentions but don't want them barking up the wrong tree and potentially missing what IS wrong.

Cookies, there are many difficulties that can 'look' like ASD. I can see why you are annoyed but a visit from the autism team wouldn't be a bad thing, if anything it will give you an idea of your Dc's strengths and difficulties then if your anything like me you can have a look into it yourself.

There is NICE guidance for diagnosing ASD and it doesn't involve a teacher diagnosing so I am with you on that one!
Our autism teachers don't even see children until they have a ASD diagnosis so tightly gatekeeped is the service.
The autism teacher cannot diagnose either it has to be Paed, Psych, EP, SLT etc as part of a team.
The autism teacher could suggest strategies which may work
If I were you I would concentrate on getting the teacher to identify what the differences / problems are - are they language, social, behaviour - then figure out where to go and what advice to get from that.
