Hi, seen another thread about SALT assessment
and got DS's latest report (dating from July) back out only to realise there are a couple of things i need to know as i don't quite get it 
The positive is that he has made progress during his time at the language unit he used to go to.
He progressed from the 1st to the 6th centile for understanding of language in just 9 months. 
And he progressed from the 0.3th to the 1st percentile with content and use of language.
DS was 4.8 y when assessment was done (2 months ago), and all of his scores were at an age equivalent of between 3 and 3.6 y old.
Now what does 'core language ' means? I understand the above but not this one. He has delay here too and has gone from 2nd to 6th percentile.
This report is quite well detailled imo, and do you think it would be useful as evidence fro SA for statement?
Thanks.
