When intelligence and educational outcomes—often assessed as years of full-time education or as highest achieved qualification, and also by school grades or educational achievement test scores—are measured at about the same time, a typical correlation is ∼0.5.

What is the correlational relationship between IQ scores and standardized achievement tests?

Published correlations between tests designed to measure general cognitive ability (i.e., “IQ”, g) and standardized achievement test scores vary but are often ∼0.7 (40, 41), with lower correlations observed when short or limited-domain IQ tests are used or when academic achievement is measured from grade-point average …

Why are IQ and achievement tests so important?

Thus, IQ and achievement tests are likely to be around for many years to come. This drives home the point that more research is needed to try to ensure that tests are used to maximize learning opportunities for all students – rather than becoming an additional barrier to some children’s achievement.

Is there a correlation between ability tests and intelligence?
