I please need some help interpreting some odd results.
I've suspected a learning disorder for some time, but DS always suddenly did better every time we almost tested.
Some background: DS is 11, we're in South Africa, and a previous test was done using the local senior scale at 7 (also because I'd read discrepancies on a test can point to any LDs if there are any. On the SSAIS he scored as superior/very superior.
He was tested using the WISC about two weeks ago, and I'm struggling to understand the results.
Verbal Comprehension (VCI): Average
Visual Spatial (VSI): Average
Fluid Reasoning (FRI): High Average
Working Memory (WMI): Very Low
Processing Speed (PSI): Low Average
Full Scale IQ (FSIQ): Not Interpretable
Visual puzzles: 12
Matrix reasoning: 12
Figure weights: 13
Digit span: 6
Picture span: 11
Letter-number sequencing: 7
Symbol search: 8
WIATT-III achievement test:
Word Reading: measures accuracy of
decontextualized word recognition.
Very High 15 years 0 months
Pseudoword Decoding: measures the
ability to decode nonsense words.
High Average >19 years 11 months
Numeracy: measures untimed, written
maths calculation skills in the following
domains: basic skills, basic operations
with integers, geometry, algebra, and
Low Average 9 years 8 months
(Just noting I'm not sure about this, as he's on dreambox and works independently, and is working across grades 5-8...)
Spelling: measures written spelling of
single words. The student hears the word
within the context of a sentence prior to
Average 12 years 4 months
The psych we saw said that while she can't calculate a FSIQ, she would guess at low-average. I just can't reconcile this to what I know about DS. He is not in any way a prodigy, but there are just too many things that point to above-average - it just jars.
I don't actually care about the numbers, I just want to understand what is going on. To me it feels like there is some kind of LD going on.
I've found some research that points to a reversal pattern of scores where IQ is low, achievement high, whereas it's usually the other way around. I have wondered about dysgraphia as he still often reverses letters and numbers. The psych said on the day he didn't present with any signs apart from using capitals in odd places (middle of words etc).
I've also read that a low coding score can be an indication of dysgraphia?
I did wonder about 4th-grade onset/stealth dyslexia as he did hit a bump at that reading level and a detailed eye test found multiple visual issues.
I was hoping to get a clearer picture of what was going on but I feel more confused. If anyone can offer some insight, I'd really appreciate it.
