ADOS Test & Social Communication Assessment Report

ADOS assessment, ADOS score, autism diagnosis

I didn’t know what to expect when we went to my boy’s ADOS assessment.  We had waited a long time to see the ‘social communication expert’ in our  area.  So I thought it might be helpful to share our experience of ADOS for those about to have an assessment. 

Don’t worry there is no need to prepare for ADOS but its always nice to understand what its all about.

What is ADOS?

ADOS stands for – Autism Diagnostic Observation Schedule. Essentially ADOS is a test to see if a child is displaying traits of autism. It is a semi-structured assessment looking at social interaction, communication and play. The assessment is a step in the process to get a diagnosis of autism

There are different modules used generally depending on the child’s age or language ability. For example if you see ADOS – 2 or ADOS – 3 the number refers to the module used.

Getting an autism diagnosis

Getting an autism diagnosis is different for each person but ADOS is a common tool used with young children.  In our case it was used alongside a social communication assessment, other speech and language reports, a common assessment framework (CAF) and standard development reports from nursery and our Health Visitor.  The ADOS test was just one step towards my son’s diagnosis.

We were first referred to speech and language in June.  The professionals we saw kept saying we should see the ‘social communication expert’, I had no idea what they meant.  It wasn’t until September that one professional explained that it means they would assess my son for autism.

It wasn’t until the following February that we got an appointment to see the social communication expert where our ADOS assessment took place.  We then waited until April to see our Paediatrician who gave us a diagnosis for my son.

What should I do before ADOS & Social Communication Assessment?

You don’t need to do any preparation for an ADOS assessment. Do read any information sent to you, this is usually just information about when and where the assessment will take place.

I know how hard it is to think about your child being assessed but the best thing you can do is be normal.  Answer all the questions honestly and let your child respond as they naturally would.  The point is to see if your child has signs of autism.  If you are not honest, the person doing the assessment may get the wrong result which in the long run doesn’t help anyone.

The letter we received was for a speech and language appointment and a social communication assessment. The letter didn’t state ADOS on it this was explained at the appointment.  It said to allow 90 minutes which was about right.

It helps to have someone with you that knows the child well. I went with my husband. You can both answer the questions even if you have different opinions. Unfortunately I also had my three month old baby with me which I wouldn’t recommend, lucky for us he slept through most of the session.  I would suggest getting childcare (if possible) for any other kids as the focus needs to be on the child being assessed.

What happens during the ADOS Assessment?

The person doing the assessment is often a speech and language therapist, it may be someone you have already seen. The assessor should explain what will happen to you before they start. The assessment is a play based observation of a child’s social communication skills.  It explores the child’s use of language and communication, two way social interaction, imagination, behaviours and interests.

What is ados

The session will be a mix of chatting with the assessor about your child and the assessor playing with your child. They will be observing your child’s social interaction and communication. They will also look at your child’s interests and any restrictive or repetitive behaviour.

It was a while ago now but I remember being nervous and finding it all a bit stressful (probably didn’t help that I was full of new baby hormones at the time).  I think it is natural to be scared and uncomfortable about any assessment related to your child.  Having said that the assessment we had was not particularly formal.  The lady who did our assessment was clearly used to dealing with stressed out parents.

The assessment took place in a room at the speech and language unit.   The room was set up with chairs for the adults and a few toys dotted around.  Over the next hour and a half we chatted with the assessor as she asked questions about our son.  She asked questions about his eating habits, sleep and interaction with others.  She also asked about our concerns, what our son enjoyed / didn’t enjoy – all questions that we could easily answer.  At the same time she was watching our son, how he interacted with the toys and us.  There was also a snack section where she was looking at how he indicated choice.

The Assessment

Throughout the session the assessor would make attempts to engage with our son.  She was speaking to him, attempting to join in his play and attempting early social games like peekaboo.  Age appropriate toys were brought out like shape sorters, cars and dolls.  Exciting things like bubbles and light up toys were used to gain my son’s attention and see how he asked for more (or walked off).  A doll was used to do more imaginative play like giving her a wash and brushing her hair.

What is ADOS

I remember thinking how well the session had gone with my son playing with all the toys and engaging with her (she was clearly used to working with children on the spectrum).   I was really struggling at home, I would try and play with him only to have him turn his back so he could play alone.

What happens after ADOS & Social Communication Assessment?

We were really lucky, towards the end of the session the lady conducting the assessment explained that she felt my son was on the autistic spectrum. She talked it through with us before saying she would refer us to the paediatrician recommending he get a diagnosis.  I remember her asking if that was OK and I wondered what she would say to parents that say no?

The assessor explained that she thought our son would need assistance now but she expected he would live a normal happy life.  I later found out she had said the same thing to other mums, to be honest when you are told your child has autism you do need someone to point out that it is OK.

My son got a high score on the ADOS assessment so it would have been easy for the assessor to make her decision there and then.  I am sure in many cases it is not clear cut and they may want time to check the scoring and their notes before making a decision.  Some local authority areas may have a policy of not revealing the score or giving any information until they have written up a report.  I think it was then a couple of weeks later we received a letter with the full report following the assessment.

If you are waiting for early years support for example a decision about inclusion funding let the assessor know. They often know the people making the funding decisions and can let them know they have seen your child.

ADOS Report

The report we received detailed the session and her assessment in the following areas:

  • Attention
  • Social communication
  • Social use of language
  • Play and social imagination
  • Rigid and repetitive behaviours
  • Sensory seeking behaviours

In the report conclusion section she highlighted significant language and social communication difficulties alongside rigid behaviours.  It also included her recommendation that he be diagnosed with an autistic spectrum disorder.  Finally it stated that she had made referrals to the paediatrician and the complex needs speech and language team.

What does the ADOS score mean?

Following the ADOS assessment you may be told your child’s score although it doesn’t really matter if you get it or not. The main aim of the test is to see if your child scores above or below the threshold for autism.

In our case a score of 12 or above indicated moderate to severe concern of ASD, my son’s score was 24.  When I received the report and our score I Googled ADOS to see what this score meant.  I got all worked up as I realised it was a very high score. I emailed the assessor with some questions after we got our report, she was very helpful in clarifying a few points for me.

The score is actually just an indication of difficulties that may indicate autism.  So a higher score is an indication that it is more obvious that my son has autism.  It means he clearly displayed the traits they were looking for through ADOS.

ADOS is one tool towards a diagnosis and it worked well for us but may not help for others, many kids perform very differently one day to the next and in different settings.

The ADOS classification includes a comparison score, this is so the results can be compared with children of the same age that don’t have communication difficulties.

Ask questions to the professional carrying out your assessment, they are best placed to explain what they are doing and what their report means.

How long does it take to get an autism diagnosis

I wish there was a straightforward answer to this but every diagnosis journey is different.  Also the standard route is likely to be different depending on where you live.  For many reasons its not possible to give you an accurate timescale.  However I can tell you it took us 11 months from initial speech referral to diagnosis.  Just based on discussions with other parents and various autism Facebook groups I would say the average wait is between 1-2 years for an early years diagnosis.

    Hi, thank you for sharing this and taking the time to do it. Our 8 1/2 yr old daughter had the ADOS part of her assessment yesterday and I needed to read something to help ‘debrief’ afterwards. That’s how I found you! It’s just helpful to read someone’s experience like your own. We should be wrapping our heads around a (likely) diagnosis today, but the doctor who was meant to conduct the parent interview section all about developmental history etc, went on study leave (!!) so we now will have to complete the process in two parts separated by about 7 weeks. I feel so disappointed and deflated having waited well over a year to get the assessment appointment only to be phoned on the morning of it to tell us about the doctor being away.
    Anyway, sorry for the life story!! And thanks again for your blog, I’ll be checking in regularly and soaking up all your info and content. Kindest regards :) Xx

      Hi Wendy, I am so pleased that you found my blog helpful. I know what you mean about needed to debrief, I imagine your head is spinning with all sorts. I also get how stressful it is waiting for a diagnosis, unfortunately it seems there is always lot’s of waiting for reports / assessments etc. At least we have autism awareness week coming up (26th March – 2nd April) so there should be lot’s about in the media, online etc. I hope your 7 week wait doesn’t stress you out too much xxx

    Hello. It’s good to reading this someone that’s been through the assessment process.. I’m pretty sure my son is on the spectrum and have the ADOS assessment in a few days time.

      I am glad you managed to read it before your son has his ADOS assessment. I think its so much easier when we understand what is happening. I hope it goes well for you and you feel prepared x

      Hi Marie. I imagine there are other factors they want to look at. ADOS is just one bit if evidence used to support a diagnosis.

      My eldest had a high score and all professionals thought he clearly was autistic so getting a diagnosis was the next step. With my youngest (who has a speech delay) we are holding off on an ADOS at the moment. We know he will score high in some areas but think some of the behaviour is learnt. A yes he has these traits wouldn’t be the right way to get him diagnosed as more work is needed with him to determine his behaviour. I would push for a clear understanding of what they want to do next. Make sure everything is explained to you so you know where you stand and what the next steps are. And don’t be afraid to disagree with professionals if you think they are wrong.

    Thank you, I found your blog very helpful. My son is 7 and has his ADOS assessment on the 27th November. Do you recommend that I take anything with me? Do I need a letter from the school? Thanks

      Hi Sammy. I am glad you found my blog useful. I don’t think you need to take anything with you as it is a stand alone assessment. You should be given lots of time to talk to the assessor throughout the assessment. If you have something you want to take there is no harm having it with you but probably not necessary. Hope it all goes well for you.
