The speech therapists in our area also focus on "normal range" - it is probably worse here as they don't report the percentiles and his school didn't recognise that "just below normal range" in our SaLT speak was actually the 9th percentile!
My son was diagnosed with autism at 3.5. He does have a high level of social interest, but this has been recognised as largely attempts to get others to follow his agenda. His speech at this time was largely echolia mixed with jargon (speech like sounds). He was improving on the surface - more stock phrases, less jargon, but the foundations weren't solid - when tested he really didn't understand simple concepts like fast and slow. The first time he was assessed by an EP, he couldn't do the block design subtest as he didn't get what copying was.
When we realised that the only intervention we were going to get by SaLT was a termly observation and an A4 sheet of paper with suggestions for the children's centre staff, we started to look elsewhere for what we could do. We started a VB program (12-15 hours a week) in January 2010 when he was a 3.11 and the improvement, particularly with his speech, has been brilliant.
He wasn't formally assessed by SaLT therapists prior to the start of the program as in our area they prefer more informal observations (probably so no one can measure progress or lake thereof). With a little pressure though, they did formally assess him in October 2010 and July 2011 using the CELF Preschool test (slightly different versions but I think you can make comparisons). I got the results this morning and I've shared them below:
Concepts and Following Directions (Last test this was Split into Linguistic Concepts and Basic Concepts).
DS scored 12. In October he scored 6 for Linguistic Concepts and 7 for Basic Concepts. He has moved from the 9/16th percentile to the 75th.
Recalling Sentences
DS scored 9. In October he scored 6. He has moved from the 9th to the 36th percentile.
Sentence Structure
DS scored 10. In October he scored 7. He has moved from the 16th to the 50th percentile
Word Structure
DS scored 12. In October he scored 8. He has moved from the 25th to the 75th percentile.
Expressive Vocabulary (Last test this was Formulating Labels)
DS scored 13. In October he scored 8 for Formulating Labels. He has moved from the 25th to the 84th percentile.
As you can imagined we are over the moon. It is such a shame we don't have the pre-VB scores as his rate of improvement definitely seemed faster in the first 10 months of the program.
I have no idea where the Dolfrog vs ABA discussion has got to while I have typed this - but I thought I would share what worked for us as light relief from the scientific journals.
