My question is what is considered a delay: say the average score is 100 and the low average is 90. Does this constitute a delay that calls for therapy? (By definition, not everyone can be above average.)
So the average range on the CELF -- which is one of the most popular and comprehensive tests of language is 86 to 114. Low average would be 78 - 85.
Having said that, it's important to understand that the test is normed on an average set of children from across the country. When kids who have advantages such as middle class parents, high quality childcare (whether from a SAHM or a quality nanny or center), fluent English models, etc . . . are looked at as a group, their scores average out close to 110. So, a student who scores 1 Standard Deviation below the "mean", will be closer to 2 SD's below the mean in their gen ed classroom in a high performing school. That can sometimes mean frustration, and academic difficulties, even for a kid with supposedly "average speech".
If I had a kid with those scores, and I could afford it without breaking the bank, I'd probably get treatment if I liked the therapist and thought my child would establish good rapport. But I also acknowledge that if you approached the public schools for help they would turn you away with those scores.
What made you get the testing in the first place?
