A. Standard Score The standard score (SS) on the WJ-III describes a client s performance relative to the average performance of the com-parison group. The scale is the same as the IQ test. In other words, the average standard score is 100 with a standard deviation of 15.

Common examples include IQ scores, personality test scores, aptitude test scores, and scores from rating scales and attitude scales [e.g., To what extent do your disagree or agree with the following statement: Congress is doing a good job: -2 (Strongly Disagree) -1 (Disagree) 0 (Neutral) +1 (Agree) +2 (Agree Strongly) ].

Interpreting Cognitive Tests

These are not IQ tests, but they do test cognitive ability which can correlate to IQ. Individually Administered IQ Tests: are done one-on one with a licensed school psychologist trained in such assessments. These give an Intelligence Quotient (IQ) score.

they do a good job of prediction: The correlations between IQ scores and both school grades and achievement test scores average about 40 to 50 but have somewhat different ranges for different samples, different tests, and different areas of achievement.


In February 2008, Pearson released Extended Norms for the WISC-IV to allow all raw score points earned to be reflected in scaled scores, Composite scores, GAI and Full Scale IQ scores. Previously, raw score points beyond a certain level were ignored, subtest scaled scores were capped at 19 and the highest global scores were limited to 150-160.

Some have argued that the cause of Black White differences in IQ is a pseudo question because race and IQ are arbitrary social constructions (Tate & Audette, 2001). However, we believe these constructs are meaningful because the empirical ndings documented in this article have been con rmed across cultures and methodologies for decades.

Making Sense of Your Child s Test Scores

If your child earns a standard score (SS) of 100, this score is zero deviations from the Mean because it is at the Mean. If your child scores one Standard Deviation above the Mean (+1 SD), the standard score is 115 (100 + 15). If your child scores one Standard Deviation below the Mean (-1 SD), her standard score is 85 (100 15 = 85).

As a result, her Expected Growth per month = 18 scale score points across 10 months, or 1.8 scale score points per month.


Full scale IQ (FSIQ), g, and racial/ethnic group differences. The FSIQ is the score that is cited as the basis for the racial/ethnic group hierarchy in intelligence, with a mean of 100 and standard deviation of 15 (e.g., Wechsler, 1997). As the literature indicates, the FSIQ is not a pure indicator of g. Subtest g

A composite score is formed by the sum (or weighted sum) of two or more tests, typically called subtests.1 This sum is then transformed into a readily interpretable standard score (e.g., scaled scores, index scores, and T-scores).

Apr 25, 2011 IQ tests provide a way of evaluating an individual s cognitive capacities relative to others of the same age. Today s widely used IQ tests, such as the Stanford-Binet and Wechsler, are considered valid because they are strongly related to real-life outcomes. For example, IQ, SAT, and ACT scores are all highly correlated, 4 and students who
