I would probably do Ravens just for a tad more understanding. If her Ravens came in low I would seriously look at not letting her be included in extension activities.
I really wouldn't keep her out of extention activities b/c of the WISC or Raven. If she can do the work without excessive stress, it is a good fit for her regardless of what those tests say. One of the kiddos I mentioned earlier with two avg IQ tests is being subject accelerated in math and in accelerated classes in other subjects and doing well. The skills that support academic achievement and the motivation are there and the child is doing well regardless of whether he is above avg or not in terms of intelligence. And I wouldn't even be sure on the accuracy of the scores you have due to other issues. They could be right; they could be wrong. Either way, I think that it is more about whether the level of work is doable by the child without anxiety.
My younger child is 2e with some very high IQ scores. I can't place her academically solely based on those IQ scores b/c the work causes her anxiety. Her disabilities interfere enough with expressing the IQ that the IQ in some ways doesn't matter in terms of placement. It can't be all about the IQ #s.
Her sister who recently tested had a WMI in the 3rd percentile. Visually older DD's short term memory is good, long term memory too,auditory well that is her weakness.
I understand my children even less than I did prior to testing.
That's why I said if we can take WMI and PSI at face value as testing what they say they are. My youngest has twice gotten avg-high avg processing speed scores on the WISC. This kid is
fast and I say that as a person who is also very fast. I've taken the adult version of the WISC and came out slightly above the 99th percentile for PSI. I have always been someone who finishes everything in half the time given. I recall a test I took as an undergrad for which we had three hours. It was a huge auditorum with hundreds of people in the class and at Berkeley, so not a bunch of slouches. I finished the test in one hour and was the first person done. The professor stopped me on the way out to talk with me about why I had finished so fast. I told her that I was just done. If I recall correctly, I also got an A.
Having the experience of being someone with that good supporting skill, I can tell you that I in no way question my older dd's lower PSI. She is not a fast person. She is deep and meticulous. My youngest is plain fast. She also has ADD and has horrible attention to detail. (I do not.) Neither of the psychs who tested dd10 gave me her scoring pattern on PSI but I'd be willing to bet a lot that it was either lower due to huge #s of errors or anxiety slowing her down.
We, ultimately, know when the strengths and weaknesses we're being given don't line up with the kids we know.
