You can also seek out a child neurologist. (How we got our son diagnosed).

The neurologist, his pediatrician, the school and us all pitched in to get a full picture of what was going on. There were some basic assessments, such as talking to him, observing him while he played, asking questions and an assessment that we all filled out.

You can also look into your local college/universities. Some will actually do free testing as part of a course work or an on-going study.

My son had a psychological evaluation to be diagnosed.

Thank you all for your suggestions. I appreciate all the input. Hugs and prayers to all of you!

@A MyAutismTeam Member. Thank you for the information. Are you in a position to say whether the main caregiver is allowed to be with the child, or is the child taken away from all the family for these diagnostics. If I (the grandmother and primary caregiver) am not allowed to be with him, I'm not sure he'd get an accurate diagnosis. (Or would that hinder?) Oh, to be a fly on the wall! lol At any rate, I'm going to prepare lists of behaviors, words, and concerns I have, and if I'm not permitted to go, my son can show it to the clinician. Thanks again!
