Different ages, different tests, different populations.

I'm sure there is a correlation between CogAT and IQ but not a direct correlation. A child can score 130 on the CogAT and have an IQ of 145 or that child can have an IQ of 125.....there is no direct correlation, (ie., CogAT SAS score of 130 doesn't equal WISC IQ score of 130)
WISC and CogAT are both ability tests. Like all ability tests, they measure slightly different things and produce different numbers. To some extent, they both measure general intelligence and the scores they produce are correlated.
Some WISC subtests are good measures of general intelligence, others are poor measures of general intelligence. WISC full scale IQ isn't necessarily a more valid measure of intelligence, especially the kind of intelligence that is required to succeed in school, than the CogAT.
The publisher is avoiding the terms intelligence and IQ because they are controversial, and people don't agree about their definition or relevance.![]()

Does anyone know what the procedure would be for a private school 3rd grader to take the MCPS test for the GT 4-5 program? I assume all MCPS kids take this test for free during school time - so what about a private school child who might be interested?

This is taken from the website of the company that publishes the CogAT:
Q: Does CogAT measure students' innate abilities?
A: No. All abilities are developed through experience. CogAT measures students' abilities to reason with words, quantitative concepts, and nonverbal (spatial) pictures. These abilities are developed through experiences in school and outside of school.
Q: Is CogAT an IQ test? Are SAS scores IQ scores?
A: No. CogAT measures reasoning abilities. Although these abilities are central to all definitions of intelligence, the word intelligence implies much more. However, psychologists have never agreed on the definition of intelligence, so how much more should be included in an intelligence test is often debated. Further, the notion of IQ comes from an earlier set of procedures for indexing the rate of mental development. CogAT does not use these procedures. The SAS scale used on CogAT provides normalized Standard Age Scores for that fraction of the population that attends school. Although SAS scores are very helpful for professionals, nonprofessionals can confuse them with IQ scores, so they are generally not reported to parents and lay organizations. Percentile ranks and stanines are better suited for general audiences.
