Ben's speech evaluation, take 5

It seems we cannot get speech therapists to agree on Ben's speech.  His speeh evaluation done as part of his developmental evaluation in October 2011 showed a severe language delay, and recommended private speech therapist.  The private speech therapist who saw him briefly dismissed him in December 2011 or January 2012 saying he'd catch up.  Early Intervention considered him to be speech delayed and so he had a speech evaluation in April 2012 as part of the process of transferring out of early intervention into preschool services.  They found him to be speech delayed and recommended twice a week speech at the local elementary school.  When we moved here, he was evaluated in the fall and the speech therapist felt his articulation was 4-6 months delayed and did not require therapy.

Same kid, different SLPs, different results.....It is a bit perplexing.

So, he was evaluated by Easter Seals by the same therapist that provided speech therapy for Liam in 2010.  She recognized him as Liam's little brother and commented how sweet and compliant he was.  He even told her he had to pee and came out to use the potty once during the evaluation.

She needs to score the results but she saw several areas of concern.
- Her biggest concern was how much Ben relies on echolalia to communicate.  She said she was surprised to hear so much echolalia, even though she knew I was concerned about it.
-He has issues with word retrieval where he knows the word but cannot seem to access it.  I need to look more into this as this is part of dyspraxia, I believe and if I am not mistaken can be connected with other issues.
-He drools and has bubbles while trying to talk, and clearly has low oral motor tone.
-He has perseveration, which means he repeats things and gets stuck.  During the testing, he'd give an answer to the previous question, not the one that was asked.
-He drops negatives and often says the reverse of what he means.
-He has pronoun confusion.

Am I the only one who notices how many of these speech issues occur in children with autism, especially the echolalia, perseveration, and pronoun confusion?
