Thank you all for your replies. I'm new to testing, so I'm still trying to figure out many of the acronyms so I can understand. Here are the tests he took and his scores:

Block design, raw: 19, scaled: 12
Similarities, raw: 22, scaled 19
Digit span, raw 17, scaled 16
Picture concepts, raw: 22, scaled 19
Coding - not taken
Vocabulary, raw 30, scaled 16
Letter-number seq, raw 10, scaled 11
Matrix reasoning, raw 20, scaled 19
Comprehension, raw 22, scaled 16
Symbol search - not taken
Picture completion, raw 21, scaled 14


Sum of scaled:
verbal: 51
Perceptual reasoning: 52
GAI 103

Composite
Verbal 142
Percep reasoning: 145
GAI 154

Percentile rank 99.9

He didn't take any tests for working memory or processing speed. Also, he was tired and resistant, so I know this test isn't fully representative. The tester pointed out some of the tests that she thinks that he scored low on because he was laying down and being reluctant. But he's 6, so that's ok.

I'm not too hung up on the IQ score, but I had told the grandparents that he got a 154, and we thought that mapped to the old IQ tests from long ago. From the chart on Hoagie's it looks like it doesn't map, and I was just trying to see what range he's in.

Is the FSIQ similar to the old IQ tests?


This is a whole new world for me, so thanks for your help!
