It is recommended that WAIS-III scores be set aside and subjects tested on the WAIS-IV and the Stanford-Binet 5. However, two new studies comparing the WAIS-III to the Woodcock-Johnson III and the Kaufman Adolescent and Adult Intelligence Scale give huge estimates. A new estimate of the extent to which the WAIS-III inflated IQs, even at the time it was normed, yields 1.65 points (rather than 2.34 points). The overall average is a rate of 0.311 points per year the average within Wechsler tests is 0.299 point per year. New data from the WAIS-IV are included in a meta-analysis of 14 combinations of Wechsler and Binet IQ tests. This ignores the fact that there is universal agreement in the scientific community that there have been substantial gains and that, therefore, the worst possible option is to simply leave inflated IQ scores unadjusted. They argue that the rate of IQ gains over time (the Flynn Effect) cannot be set at 0.3 points per year with scientific exactitude therefore, the adjustment formula that rate implies is inadmissible in capital cases. If you have WAIS scores to send me, DM me.Daubert motions oppose adjusting IQ scores. Anyone that has taken matrices tests in the past can take it.Įdit: VCI is no longer available on classmarker, as people. If anyone is interested in trying it, let me know. People that have taken the WAIS only please.Īlso, I have a new high range matrices test that I would like to norm. If you have questions about the test please read the intro/FAQ before sending me a message.Įdit: For those interested, I am also looking at testing another CAIT Subtest. Please only use the classmarker links for the PRI section or if you've taken the WAIS before and want to submit your results for data collection.Īs part of the update, the norms and data reports have been updated based on the analysis of the data from the last round of testing.
The VCI subtests have been automated thanks to MelerEcckmanLawler and can be taken at any time. Composite scores relating to specific cognitive areas may also be. In addition to subtest scores a combined composite score is reported (the IQ). There are 15 subtests on the WISC-IV but they may not all be used.
You can read more about the WISC-IV here. **Please only take the PRI section on classmarker once please.ĬAIT will be back online again in the next few hours. Older children and adults are tested using the Wechsler Adult Intelligence Scale (WAIS). If you haven't taken it and want to, send me a message and at some point I will send you a password protected link for a single attempt. This is to conserve credits, as the tests have not yet been automated. I am only allowing people to take it if they have not taken it before, and one attempt only.
PRI will be available again on Jan 6th but by REQUEST ONLY.
