TECHNICAL REPORT

These norms are used to furtherdifferentiate highly gifted children (FSIQ orGAI above 150) from gifted children (FSIQor GAI 130150). The extended norms areuseful when a childs score is themaximum (ceiling) on two or moresubtests (e.g., obtains scaled scores of 18or 19 points). These norms extend theWISCIV upper scaled score range to 28points for subtests and 210 points forcomposites. It is important to note that theextended norms are not useful for mostchildren. Among the 2,200 cases in theWISCIV standardization sample, onlyone child obtained a GAI score of 151 andnone obtained an FSIQ score of 150 orhigher. According to the bell curve, out of20,000,000 same-age peers, only onechild would be expected to obtain a FSIQof 180 or higher.

TheWISCIV extended norms weredeveloped using the natural ceiling of thetest,WISCIV standardization data, andthe validity data (highly gifted sample)provided by the NAGC. These norms arebased on the same measurement metricsused in all Wechsler scales, same-agepeers, and are consistent with the normalbell curve. These features ensure themeaningful comparison of IQ and indexscores derived from all current Wechslerscales or other tests that use the samemeasurement metrics. NAGC provided thevalidity data as a benchmark to guidedevelopment of the extended norms. Dr.Linda Silverman of NAGC also providedtwo cases categorized as extremely giftedto beta test the extended norms. NAGCexperts confirmed that scores from thesecases were within the expectation.

The rate of concept acquisition is highestduring early ages. As a result, median rawscore changes across the younger ageswill be greater than median raw scorechanges with adolescents. Smallerchanges in median raw scores at higherability levels will represent larger andlarger differences in calculated mentalages. Therefore, age-equivalents basedon these median raw scores cannot beconsidered equal interval or ratio scalesand therefore, should not be added,subtracted, divided or multiplied (seeBracken, 1988; Harrison & Oakland,2002).

TheWISCIV extended norms describedin this report are more psychometricallysound and easier to compute than ratiocomputations based on age equivalentsdata (e.g., mental age biological age x100). For the purpose of interpretation, allthe tables provided in theWISCIVmanual, such as reliability, SEM, criticalvalues, and base rate tables, can be usedto interpret the scores derived from theextended norms. The scores derived fromthe extended norms should be interpretedthe same way as any other standardscores derived from theWISCIV. Thefollowing wording is recommended whenthe extended norms are used:

Because {childs name} obtainedthe top scaled score on {number ofsubtests}WISCIV subtests, his/hercomposite scores were based on aspecial table of extended normscreated, in part, from a sample ofhighly gifted children (see theWISC-IV Technical Report #7).Using these extended norms, his/herscores are as follows: . . .

The WISCIV extended norms were developed in response toa request from the National Association for Gifted Children (NAGC).

Because the natural ceilings of theWISCIVsubtests are not equally high, the maximum scaledscores are not the same across all subtests. Themaximum scores across all ages may not beequally high because of these ceiling differences.The possible extended scaled, IQ, and indexscores are higher for a younger child, so his orher scores could be lower when assessed a fewyears later (depending on the length of thetesting interval).

The extendedWISCIV norms are veryinformative in differentiating highly gifted childrenfrom gifted children; however, this new endeavorrequires further clinical validation.

Validity Study Using National Associationfor Gifted Children SampleThe NAGC sample contains 157 usable cases witha mean age of 8.71 years, the SD = 1.85 years,

ranging from 5.64 to 13.8 years. The sampleconsists of 61% males and 39% females. Table 1reports the mean subtest, index, and IQ scores ofthe sample. Table 1 shows that scores based onthe extended norms average about 1 to 2 pointshigher than the scores based on the regularnorms. The maximum score and variance foreach composite score significantly increased.As expected, the composite scores with highg-loading, e.g., VCI, PRI, and GAI, show the mostincreases in the maximum score. About 37.2% ofthe sample showed 1 to 17 points improvementwhen the extended GAI norms were used. Incontrast, only 2.3% of theWISCIVstandardization sample showed 1 to 3 pointsimprovement when the extended GAI norms wereused. These results indicate that theWISCIVextended norms indeed improved thedifferentiation among the gifted children.

Case Study

Name: K.O. D.O.B. 10/30/99Sex: Male Test Date: 3/26/07Age: 7 years 4 months

Because K.O. obtained the top scaled score on elevenWISCIV subtests, his subtest scaled score, andcomposite scores were derived from specialWISCIV extended norms created, in part, based on asample of highly gifted children. Using the extended norms reported inWISCIV Technical Report #7(The Psychological Corporation, January 2008) his scores are as follows:
