the claim

IQ tests have high test-retest reliability and predict academic achievement.

the verdict
CONTESTED PARTIAL
Recorded sources
1 source for · 1 against

Counts group repeated records of the same source within each side. They do not measure evidence strength or source independence.

Is it true that IQ tests have high test-retest reliability and predict academic achievement?

Partly. One item reports that the Wonderlic, an IQ-type test, has high test-retest reliability (about .87), covering only the reliability half of the claim. Another item argues that high school GPA predicts college graduation better than SAT/ACT scores, partially undercutting the predictive-validity half. No retrieved item directly addresses IQ tests predicting academic achievement.
