On another forum, a mother of a 10 year old adopted DD, that had pre-natal substance exposure.
Has been offered an assessment using the WAIS test. (Weschler Abreviated Intelligence Scale)
Asking if she should request a WISC test instead?
But I looked into WAIS, which also provides what is officially recognized as a valid IQ score.
Just as Weschlers WISC test, is also recognized as providing a valid IQ score.
Though I looked for research that compared WAIS with WISC ?
Where I found a study that did a comparison study?
Crucially what it identified?
Is that when a group of students did both the WAIS and WISC tests?
Which both report an IQ score.
That on average, they had an average 12 point higher IQ score on the WAIS test.
(With a range from 10 to 15 points higher)
Yet an important point, is that both tests are officially recognized, as providing valid IQ scores.
So that we can have 2 different valid IQ scores, depending on which test we did?
In the conclusion of this study, they raised the question about how this related to an assessment for IDD Intellectual Development Disorder, ( the new term for Mental Retardation).
Where using the WAIS test with its 12 point higher IQ score, would remove many from qualifying as IDD, and denying them access to services.
Yet if they had done the WISC test, they may have qualified?
Where we are not talking about just a couple of points difference?
But an average 12 point difference!
Though I'm also thinking about this, in relation to FASD and pre-natal substance exposure?
Where a child might be given a WAIS test, instead of WISC test?
The A in WAIS stands for 'abbreviated'.
I can see how a parent could agree to an 'abbreviated' test instead, being less of a strain.
Having been told that it will provide an officially recognized IQ score.
What they wont be told, is that it will artificially inflate their IQ score, by 10 to 15 points?
Whilst this test might be given to a child?
That reports their IQ at that age, as part of their documented history.
With an IQ that has been inflated by 10 to 15 points.
When perhaps 10 years later, they do the other WAIS test?
(Weschler Adult IS, instead of Weschler Abbreviated IS)
Their would be a 10 to 15 point drop in the IQ scores.
Which in fact, was not actually a drop in IQ ?
But was a result of using a different test !
What really concerns me, is how an abbreviated WAIS test could contaminate one's history?
If one has FASD or IDD?
So that as maybe a 20 year old, they apply for services?
Which requires providing a history of testing.
Where this abbreviated WAIS test as a 10 year old, shows that they had a significantly higher IQ when they 10 years old.
Which has declined since then.
But FASD and IDD, will have effects from birth, and wont just cause an IQ decline after the age of 10.
So that a much earlier WAIS (abbreviated) IQ score, could be used to deny services?
As their was no difficulty before the age of 10.
Though I can't understand how both of these tests can provide a valid officially recognized IQ score?
If they both provide very different scores?
