Hi, my son is finally having an ADOS test in May. Do you think it is a good indicator for autism if they are high functioning? What are your experiences? He is 4 and some days I think he fine, what am I worried about, as he has improved a lot in certain areas. Other days I think it's ASD for sure. Curious on what they look at in the test. There's so much information on the internet and much of it is American. It's starting to hurt my head so thought I would ask on here. Thanks!
