Is the NVI recommended for students with varying degrees of communication deficits? Could you use the NVI to determine eligibility for students who are nonverbal? The NVI may be especially useful in these types of situations. The GAI provides an estimate of general intellectual ability that is less impacted by working memory and processing speed than the FSIQ.

Children with neurodevelopmental disorders associated with difficulties in working memory and processing speed, such as learning disabilities, ADHD, Language Disorder, or autism spectrum disorder, may obtain lower FSIQ scores than children without such difficulties. In these situations, the lower FSIQ score may mask meaningful differences between general cognitive ability represented by the FSIQ and other cognitive functions e.

The GAI was developed to help practitioners with the identification of relative strengths and weaknesses that are based on comparisons between general ability and other cognitive functions. Compared with the FSIQ, the GAI provides the practitioner with an estimate of general intellectual ability that is less sensitive to the influence of working memory and processing speed by excluding those subtests.

The FSIQ can be compared to the GAI to assess the effects of a weakness in cognitive proficiency as measured by the working memory and processing speed subtests on the child's overall cognitive functioning. In some situations, it may be appropriate to use the GAI for score comparisons with measures of achievement or other cognitive functions.

There is not an analogous table that reports these data by special group. Table C. Because this procedure estimates performance on a primary subtest using a secondary subtest, the results should be interpreted with caution and considered non-standard. A maximum of one substitution may be made when deriving the FSIQ only. No substitutions can be made for any other composite score. The potential FSIQ substitutions are limited in order to constrain additional measurement error that may be introduced by this practice.

Table 2. How was it decided that one subtest score could or could not be substituted for another when deriving the FSIQ? Because substituted subtests are being used as an estimate of performance on another subtest, only secondary subtests within the same cognitive domain that are highly related to the primary subtest can be substituted.

Can I administer all of the primary and secondary subtests and choose to use the highest subtest scaled scores when computing the FSIQ? When deriving the FSIQ, you can only substitute a secondary subtest for a primary subtest that is spoiled or invalidated, or for a specific clinical purpose.

Secondary subtests can also provide additional information on cognitive functioning. If you need to substitute a secondary subtest in place of a primary subtest for deriving the FSIQ, it is best practice to decide this before you administer the subtest—not after you have derived scaled scores. Secondary subtests are also useful when the primary subtest scores that contribute to a primary index score are widely discrepant.

In this situation, additional information from secondary subtests can help to shed light on factors that may contribute to such disparate results.

Because subtest substitution may introduce measurement error into derived composite scores, substitution is limited. The index scores are derived from fewer subtests than the FSIQ, therefore, the risk of such error is greater. If a secondary subtest substitutes for a primary subtest for the FSIQ, the Q-globalTM scoring software will not allow calculation of the primary index score that the primary subtest contributes to.

Prorating is available for the FSIQ only. A maximum of one proration or substitution may be made when deriving the FSIQ. Proration and substitution may not be combined to derive an FSIQ.

Having low scores on both components i. If you are familiar with the statistical phenomenon of regression to the mean, then this will make sense. If not, think about an Olympic gymnast competing in the all-around. It is rare to see someone score a perfect 10 on every event. It is more common to see them score a perfect 10 on one event and 8s on the others. The same applies to low scores.

There is a tendency for subsequent observations to be less extreme. Is the Full Scale IQ invalid if index scores are discrepant? Is an index score invalid if subtests are discrepant? Some interpretive approaches posit that composite or index scores are less valid or less reliable if their component parts are discrepant. In these interpretive approaches, the Full Scale IQ or an index score is described as valid, reliable, and interpretable only if no significant discrepancy exists between the highest and lowest primary index scores.

Similarly, the index scores are only described as valid and reliable if their contributing subtests are not significantly discrepant. There does not exist evidence that there is a discrepancy or index score scatter beyond which the Full Scale IQ becomes invalid, unreliable, and uninterpretable. When great variability or discrepancy characterizes the primary index scores or the subtest scaled scores, the Full Scale IQ alone is insufficient to describe a child's intellectual abilities obviously a lot more description would help.

Reliance on any single score is never recommended for describing a child's intellectual abilities or for identifying his or her strengths and needs. Also, not all of the subtests that contribute to index scores are always used to create the FSIQ; the FSIQ is derived from a subset of those primary subtests Recent research indicates that the Full Scale IQ has equal construct and predictive validity regardless of primary index score discrepancies.

The construct and predictive validity of the Full Scale IQ is independent of the discrepancy Daniel, Similarly, the construct and predictive validity of the primary index scores is independent of the amount of discrepancy between subtests Daniel, Furthermore, it is quite typical to have a discrepancy of greater than 1. In fact, Similarly, Kaufman et al. With respect to the Full Scale IQ's reliability in the presence of relatively large discrepancies among primary index scores, there is no evidence that the Full Scale IQ becomes unreliable in these circumstances either some people feel intuitively that it does.

For example, Table 4. For the special groups with larger scatter among primary index scores, the subtest reliabilities are comparable with those of other special groups with smaller scatter among primary index scores e. Because these coefficients are comparable with those of the normative sample, it is more likely that the Full Scale IQ reliability for special samples would be similar to that of the normative sample. The data indicate very few individuals obtain larger differences.

Shouldn't it be 65? Many people find this result counterintuitive, but it is correct. First, consider that the FSIQ is used to predict the student's true intelligence and does not correlate perfectly with it. In this case, if the student's true FSIQ is 57, then his or her index scores should be higher than 57 due to the effect of regression toward the mean. On the other end of the continuum, the opposite is true. This effect can be found in the composite score norms tables of many tests of cognitive ability, though the strength of the effect depends on several factors, including the number of subtests entering the composite, the distance of the subtest scores from the mean, and the correlation among those subtests.

When a composite is made up of more subtests, the effect is larger. It is rarer to score about 2 standard deviations below the mean on each of the 7 subtests that compose the FSIQ than on each of the two subtests that compose an index score. This is why the effect is more pronounced for the FSIQ than for any of the five index scores. The further a score is from the mean, the larger the effect.

This is because it is rarer to score about 2 standard deviations from the mean on all 10 primary subtests than it is to score 1 standard deviation from the mean all 10 subtests. The effect is usually more pronounced at 2 standard deviations from the mean than at 1 standard deviation from the mean. Beyond this point, the minimum and maximum possible scores constrain the effect.

Think about an Olympic gymnast competing in the all-around. It is more common to see them score a perfect 10 on one event and 8's on the others.

Great performance on multiple subtests is more rare, so it results in a higher composite score. The result is more unusual. What is it for? Do I need to carry it with me? The supplement contains all tables needed to fill out the Ancillary and Complementary Analysis and Process Analysis pages of the Record Form.

You do not need the supplement during administration. You will only need it during scoring and only if you wish to supplement the primary analysis using these other scores. Stimulus Books 1 and 2 are necessary when administering the 10 primary subtests. Stimulus Book 3 is necessary when administering the complementary subtests. Where do I record process observations and contrast scores on the Record Form? Where are the instructions about how to calculate these scores?

The Record Form does not provide designated space to tally or derive process observations or contrast scores because they are not used for every administration or by every practitioner. The Record Form pages associated with each subtest and with summary and analysis were also subject to horizontal and vertical space limitations. These limitations are due to the maximum amount of printed and white space and pages available within a durable, bound paper booklet. There was simply not room to include these optional scores.

Page 76 of the manual provides instructions on using the tables in Appendix D of the WISC—V Technical and Interpretive Manual to obtain the normative information for selected process observations for certain subtests. The Record Form also does not provide space to derive contrast scores. However, Appendix C of the WISC—V Technical and Interpretive Manual contains the necessary directions and tables to derive these scores, as well as the corresponding interpretive information.

On the Process Analysis page in the Raw Score to Base Rate Conversion table, the number of errors sometimes occurs with multiple base rates. What should I do? Use the smaller of the two numbers because of how cumulative percentages are calculated. Refer to p. Q-global is a web-based scoring and reporting platform that offers accessibility from any computer connected to the Internet.

It allows for quick and automatic organization of examinee information and the ability to generate scores and produce accurate and detailed results. You can reprint a report at no charge if you change any demographic or report options. However, if you alter raw data, a new record is created and a new report usage is required to print the output. Choose your substitution in the drop-down menu. On rare occasions, an inadequate number of valid subtest scores are obtained to derive the FSIQ, despite the availability of secondary subtests.

Q-global automatically prorates the FSIQ if a primary subtest that contributes to it is missing and a secondary subtest is not selected for substitution.

If more than one primary subtest is missing, the FSIQ is not calculated. Proration is only available for the FSIQ and only when the prorated sum of scaled scores is based on primary subtests. You cannot combine subtest substitution and proration when deriving the FSIQ.
