Data Collection: Old and New IQ Test Score Pairs

by Carolyn K., director, Hoagies' Gifted Education Page

Many people have asked, will I create a table comparing the old and new IQ test scores, similar to the WISC-III and/or WPPSI-R vs. SB L-M data? Here it is, your chance to contribute your child's scores to the anonymous data for this new table.

For this new table, I'm collecting data comparing gifted children's scores on now the old versions WPPSI-R, WISC-III or SB-4 to the same children's scores on the new versions WPPSI-III, WISC-IV or SB-5. (SB L-M scores on the same children as the old and new test pair are optional, and appreciated) The entry form below will show which scores I'll put in the table.

To be a data point, the child must have scores from at least one old test and one new test, and complete data for each test must be provided, including full scale score, subscale scores, subtest ceilings, and age at testing. One of the two test scores must be full scale >120.

Submitting data via this form is anonymous, unless you choose to provide your e-mail address. While I would appreciate the chance to confirm the data, an e-mail address is in no way required.

February, 2007 Current count: After putting the data into Excel for analysis, I discovered that I have a total of only 11 complete data points for WISC-III to WISC-IV comparison, and 3 data points for various combinations of tests including Stanford Binet scales as either the old or new IQ test. Many of the data points submitted are missing either the old or new IQ test scores, and without this combination, they are not useful for this study. The data still overly represents boys - if you have a girl who has been tested on both WISC-III and WISC-IV, please contribute! I apologize, but must preserve the anonymity of the children.

Currently, the data is showing an average score of 137.7 for the WISC-III or WPPSI-R, compared to an average score of 135.4 for the WISC-IV, for an average loss of 2.45 IQ points between the old and new versions. Of the 11 data points, 7 lost IQ points between the two tests, while only 4 gained points. The average number of subtest ceilings dropped from 4.8 ceilings on the old test, to 3.5 ceilings on the new test.

Please consider submitting your child's scores for a data point, if you have both a WISC-III or WPPSI-R and a WISC-IV score. Thank you!

Thanks for your participation!

Was there anything unique about the administration of either test? Was the child sick, tired, unhappy for either testing? Were any twice exceptionalities noted? Anything else...
