Academic achievement in mathematics and science of students between ages 13 and 23: Are there differences among students in the top one percent of mathematical ability?

The predictive validity of the Scholastic Aptitude Test-Mathematics subtest (SAT-M) was investigated for 1,996 mathematically gifted (top 1%) 7th and 8th graders. Various academic achievement criteria were assessed over a 10-year span. Individual differences in SAT-M scores obtained in junior high school predicted accomplishments in high school and college. Among students in the top 1% of ability, those with SAT-M scores in the top quarter, in comparison with those in the bottom quarter, achieved at much higher levels through high school, college, and graduate school. Of the 37 variables studied, 34 showed significant differences favoring the high SAT-M group, which were substantial
